▼ Increased pulsatile release of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) is critical for pubertal initiation of ovarian cycles in female mammals. Kisspeptin, a peptide product of the Kiss1 gene, is required for normal puberty. In Experiment 1, ovariectomized ewe lambs bearing subcutaneous estradiol implants were used to investigate Kiss1 gene expression in the preoptic area (POA) and hypothalamus during pubertal maturation of the reproductive neuroendocrine system. Brain tissue was collected from ewes at 25, 30, and 35 wk of age (n=6/group). Patterns of LH release in circulation were determined on the day before euthanasia and cells containing Kiss1-mRNA were identified by in situ hybridization. Mean concentrations of LH and the frequency of LH pulses increased (P < 0.01) as ewe lambs matured. In the POA/Periventricular area (PEV), the number of Kiss1-expressing cells was greater (P < 0.04) in 30- and 35-wk-old than in 25-wk-old ewe lambs. In the arcuate nucleus (ARC), although no significant changes in number Kiss1-expressing cells were observed among age groups, the number of Kiss1 cells increased (P < 0.02) with increased frequency of LH release. This resulted in greater (P < 0.01) number of Kiss1 cells in the ARC of ewes demonstrating elevated frequency (> 6 pulses/12 h) of LH pulses. In Experiment 2, 28-wk-old ewe lambs were used to determine the effects of intermittent injections of kisspeptin on the release of LH and stimulation of gonadal function in peripubertal ewe lambs. Ewe lambs were treated intravenously with saline (Controls; n=6) or kisspeptin (n=6) hourly for 24 h. Blood samples were collected throughout the experiment for hormone analysis. Kisspeptin-treated lambs had greater (P < 0.02) mean circulating concentrations of LH, and frequency and amplitude of LH pulses than controls. Four of six kisspeptin-treated ewe lambs exhibited LH surge and luteal activity in response to treatments. However, onset of regular estrous cycles was not established immediately following kisspeptin-induced ovulation and no difference in age at onset of puberty was observed between groups. In conclusion, activation of the hypothalamic kisspeptin system may support elevated episodic release of LH critical for establishment of normal estrous cycle during pubertal development.

▼ Adolescent girls are susceptible to knee injuries such as non-contact anterior cruciate ligament (ACL) rupture and patellofemoral pain (PFP). Adolescence is synonymous with pubertal development which drives substantial growth and maturation of the musculoskeletal system, and is thought to contribute to poor knee biomechanics associated with both of these injuries. Specifically, higher tri-planar knee moments during puberty (external peak knee abduction moment (KAbM), flexion moment (KFM) and internal rotation moment (KIRM)) are thought to contribute to a higher incidence of these injuries; however, there are still gaps in our understanding of female pubertal biomechanics. For instance, variations in dynamic tasks (i.e., bilateral vs single limb), unreliable pubertal classification methods, small sample sizes, conflicting findings and data normalisation methods (i.e., mixed between body mass or body mass by height) highlight the need for additional, better designed pubertal studies. The role of athletic footwear is also an important consideration, given it may alter tri-planar knee moments relevant to both non-contact ACL rupture or PFP. Specifically, high-support footwear is thought to control excessive foot pronation, which may transfer up the kinetic chain and confer protection at the proximal knee joint by modifying tri-planar knee moments during dynamic tasks. By contrast, low-support shoes do not possess the same stability features, potentially allowing for greater foot pronation that may have a clinically meaningful effect on tri-planar knee moments compared to high-support shoes. Surprisingly, no studies have explored the effects of these shoes during female pubertal development, which is concerning as many adolescent girls are likely wearing these types of shoes during the various sports in which the aforementioned knee injuries occur. To address the current limitations in pubertal and footwear biomechanical research, four cross-sectional studies are reported in this thesis. Ninety-three girls aged between 7-25 years old were categorised into three key stages of puberty: pre-pubertal (n = 31, mean age = 9.4 ± 1.2), early/mid-pubertal (n = 31, mean age = 11.1 ± 1.4) and late/post-pubertal (n = 31, mean age = 19.8 ± 4.0). Tri-planar knee moments normalised to body mass (Nm/kg) and body mass by height (Nm/kg/m) were analysed across landing and running-related tasks in each pubertal group. These were initially observed barefoot, and then subsequently, the effect of high- and low-support footwear was explored across both tasks. The primary aim of Study 1 was to determine whether peak tri-planar knee moments differed between three stages of female pubertal development during a barefoot single limb drop lateral jumping (DLJ) task. The secondary aim was to explore the hip adduction moment (HAM) at time of peak KAbM and the hip flexion moment (HFM) at time of peak KFM between pubertal groups. In the frontal plane, a higher peak KAbM was found for the late/post- compared to the pre-pubertal group when…

▼ Manganese (Mn) is considered important for normal growth and reproduction. Because Mn can cross the blood brain barrier and accumulate in the hypothalamus, and because it has been suggested that infants and children are potentially more sensitive to Mn than adults, we wanted to determine the effects of Mn exposure on puberty-related hormones and the onset of puberty, and discern the site and mechanism of Mn action. We demonstrated that the central administration of manganese chloride (MnCl2) stimulated luteinizing hormone (LH) release in prepubertal rats. Incubation of medial basal hypothalamus (MBH) in vitro showed this effect was due to a Mn-induced stimulation of luteinizing hormone releasing hormone (LHRH). Further demonstration that this is a hypothalamic site of action was shown by in vivo blockade of LHRH receptors and the lack of a direct pituitary action of Mn to stimulate LH release in vitro. Chronic supplementation of low dose of MnCl2 caused elevated serum levels of LH, follicle stimulating hormone (FSH) and estradiol or testosterone. Importantly, Mn supplementation advanced the timing of puberty in both sexes. We investigated the mechanism by which Mn induces LHRH/LH release from the hypothalamus. Blocking the NMDA receptor, IGF1 receptor, or inhibiting nitric oxide synthase in vivo was ineffective in altering Mn-induced LH release. Dose-response, pharmacological blockade and nitrite assessments indicated that the lowest doses of Mn used stimulated LHRH release, but did not induce nitric oxide (NO) production, while only the highest dose of Mn stimulated NO. Conversely, a dose-dependent inhibition of Mn-induced LHRH release was observed in the presence of ODQ, a specific blocker of soluble guanylyl cyclase. Furthermore, Mn stimulated the release of cyclic GMP (cGMP) and LHRH from the same MBH, and a protein kinase G (PKG) inhibitor, KT5823, blocked Mn-induced LHRH release. Collectively, these data demonstrate that Mn can stimulate specific puberty-related hormones both acutely and chronically, and furthermore, suggest that low levels of Mn facilitate the normal onset of puberty. The principal action of Mn within the hypothalamus is to facilitate the activation of guanylyl cyclase, which subsequently stimulates the cGMP/PKG pathway resulting in the stimulation of prepubertal LHRH secretion.

▼ The pubertal initiation of a high-frequency, pulsatile release of gonadotropin-releasing hormone (GnRH) involves an escape from estradiol negative feedback. Kisspeptin neurons are proposed to mediate the effects of estradiol, and estrogen receptor alpha (ESR1) may play a role in this process. The present study investigated the hypothesis that reduced ESR1 expression in kisspeptin neurons is associated with decreased sensitivity to estradiol negative feedback that underlies reproductive maturation. Ewe lambs were ovariectomized at approximately 24 wk of age and received no implant (OVX; n=7) or received a subcutaneous implant containing estradiol (OVX+E; n=14). At 30 wk of age, blood samples were collected to characterize the pattern of luteinizing hormone (LH) secretion. Lambs were then euthanized and a block of tissue containing the preoptic area (POA) and hypothalamus was collected. Detection of ESR1 mRNA and kisspeptin was performed by dual-label in situ hybridization/immunocytochemistry. The abundance of ESR1 mRNA in the middle arcuate nucleus (mARC) was greater in OVX than in OVX+E ewe lambs but did not differ between groups in any other hypothalamic area investigated. Posthoc analysis of the LH data obtained from OVX+E lambs indicated three distinct patterns of LH release: low (1-2 pulses/12 h; n=3), moderate (6-7 pulses/12 h; n=6) and high (>10 pulses/12 h; n=5) frequency of LH pulses. The proportion of kisspeptin cells containing ESR1 mRNA in the POA/periventricular area did not differ among OVX+E lambs exhibiting low, moderate and high frequency of LH pulses. However, the proportion of kisspeptin cells containing ESR1 mRNA in the mid ARC was greater in OVX+E lambs exhibiting high frequency of LH pulses (0.57) than in lambs exhibiting moderate (0.36) or low (0.27) LH pulsatility, and did not differ from OVX (0.50) lambs. Contrary to our hypothesis, the increase in LH pulsatility in maturing ewe lambs is associated with enhanced ESR1 expression in kisspeptin neurons in the ARC. This indicates that the mechanism of decreased sensitivity to estradiol negative feedback during maturation of the reproductive neuroendocrine axis does not involve limiting ESR1 transcription in kisspeptin neurons.

▼ Throughout sexual maturation, dynamic changes in testicular macro- and microstructure and reproductive hormone levels occur. Future adult reproductive capability is critically dependent on these changes; therefore, regular monitoring of pubertal testicular development is desirable. However, conventional methods of assessment do not permit the frequent and non-invasive examination of testicular function. Recently, scrotal ultrasonography in conjunction with computer-assisted image analysis has emerged as a potential non-invasive alternative for male reproductive assessment. In this procedure, testicular echotexture, or the appearance of the ultrasonogram, is objectively quantified on the basis of brightness or intensity of the minute picture elements, or pixels, comprising the image. In general, testicular pixel intensity increases with age throughout sexual maturation; however, periodic fluctuations occur. Changes in testicular echotexture are related to microstructural attributes of the testes and reproductive hormone secretion, but reports on these relationships have been inconsistent. Therefore, the overall objective of the studies presented in this thesis was to investigate how testicular echotexture and its associations with testicular histomorphology and endocrine profiles may be influenced by various factors including: i) scrotal/testicular integument; ii) blood flow/content; iii) stage of development; and iv) altered spermatogenic onset. Serial scrotal ultrasonograms, testicular biopsies or castrations and blood samples were collected from early postnatal or peripubescent ram lambs and analyzed to obtain echotextural, histomorphological and endocrine data, respectively. Testicular echotextural attributes were influenced by the presence of the scrotal and testicular integument, the stage of spermatogenic development (mitotic vs. post-mitotic) and the amount of germ cell heterogeneity present with or without retinoic acid exposure, but not by blood flow or content. Tubular and luminal size of the seminiferous tubules could be predicted from testicular pixel intensity using a simple linear regression model and demonstrated a moderate strength correlation with testicular echotextural parameters, as did a number of cellular and sub-cellular histomorphological attributes and reproductive hormone levels. These results clearly demonstrate the ability of testicular echotexture to detect experimentally and clinically relevant markers of testicular function. Computerized image analysis of scrotal ultrasonograms holds promise as a non-invasive diagnostic and prognostic tool and novel monitoring device of testicular histophysiology.

▼ Menstruation is a significant milestone in a woman’s life, signifying the onset of puberty and the journey into womanhood. Yet research suggests that the construction of menstruation has many women feeling uncertain and negative about menstruation, and what it means for them. Within the research literature I found four dominant discourses that construct our understandings of menstruation; menstruation as a hygiene crisis that needs rigid management, menstruation as a shameful secret that must be concealed, menstruation as biological and medical where the purpose of menstruation is restricted to pregnancy or illness, and menstruation as constitutive of womanhood in terms of motherhood, and femininity. My review of the research literature led me to design a project to examine the ways menstruation is currently constructed within puberty education, with a particular interest in the various discourses presented to young women. I look at how the girls take up and/or resist these discourses as well as look at the subjectivities made available from them. Finally I examine the ways a wider variety of discourses can be made available and in turn a greater range of subjectivities. As a feminist poststructuralist, I am looking specifically at issues of gender and sexuality, and how meaning and knowledge is constructed through language and discourse. With this as my theoretical framework, I observed three lessons, each teacher’s specific lesson on menstruation, and a concluding joint girl-only lesson, within a puberty unit of a New Zealand intermediate school, conducted individual interviews with the two teachers and focus group the interviews provide the data of this research. Using a discourse analysis approach to examine my data I was able to show the four dominant discourses were still present in the teaching of menstruation at the study school. I also found three discourses that, although not new, appear to be under examined within the construction of menstruation. These discourses of dread, consumerism and celebration may contribute to the dominant constructions of menstruation and/or offer ways to challenge and subvert these constructions. By making visible these discourses and the ways they construct menstruation, I am not looking to locate the ‘correct’ way to teach or understand menstruation. However, I argue that by supporting young women and their teachers to critically analyse the various discourses that shape our understandings of menstruation, we may create opportunities to challenge and resist the dominant constructions as well as open up a wider range of subjectivities.

▼ Background/Objective During adolescence, chronotype shifts towards “eveningness.” “Eveningness” is related to negative physical and mental health outcomes. Little is known about what influences the shift in chronotype beyond pubertal status. The current study examined the influence of earlier depression predicting later individual differences in adolescent chronotype, accounting for pubertal status, and the prospective prediction of later increases in depression from earlier chronotype. Methods Youth (age M=12.06, SD=2.35; 56.5% girls) from the community completed repeated assessments of depression, including both self-reports (14 assessments) and diagnostic interviews (8 assessments), over a 48-month period. At the 36-month time-point, participants completed chronotype and pubertal development measures. Regression and ANOVA analyses examined: (1) the influence of earlier depression levels (baseline to 36-months) upon chronotype, and (2) chronotype (at 36 months) upon later depression (48 months). Results Youth with higher earlier depression symptoms (β=-.347, p<.001) and history of depression diagnosis (β=-.13, p=.045) showed a greater eveningness preference controlling for pubertal status, age and gender. Further, depression diagnosis history interacted with pubertal status to predict chronotype: (F(1,243)=4.171, p=.045) such that the influence of depression on chronotype was greatest among postpubertal youth (t=3.271, p=.002). Chronotype (greater eveningness preference) predicted prospective increases in depression symptoms (β=-.16, p=.03) and onset of depressive episode (b=-.085, OR=.92, p=.03) one year later. Conclusion Depression, experienced earlier in life, predicts greater preference for eveningness, especially among postpubertal youth. In turn, later depression is predicted by evening preference. These findings suggest the reciprocal interplay between mood and biological rhythms, especially depression and chronotype, during adolescence. Advisors/Committee Members: Hankin, Benjamin L.

▼ The genetic control of puberty remains an important but mostly unanswered question. Late pubertal timing affects over 2% of adolescents and is associated with adverse health outcomes. Self-limited delayed puberty (DP) segregates in an autosomal dominant pattern and is highly heritable; however, its neuroendocrine pathophysiology and genetic regulation remain unclear. The genetic control of puberty remains an important but mostly unanswered question. Late pubertal timing affects over 2% of adolescents and is associated with adverse health outcomes. Self-limited delayed puberty (DP) segregates in an autosomal dominant pattern and is highly heritable; however, its neuroendocrine pathophysiology and genetic regulation remain unclear. Our large, accurately phenotyped cohort of patients with familial self-limited DP is a unique resource with a relatively homogeneous genetic composition. I have utilised this cohort to investigate the genetic variants segregating with the DP trait in these pedigrees. Whole exome sequencing in eighteen probands and their relatives, and subsequent targeted sequencing in an extended subgroup of the cohort, has revealed potential novel genetic regulators of pubertal timing. In ten unrelated probands, I identified rare mutations in IGSF10, a gene that is strongly expressed in the nasal mesenchyme during embryonic migration of gonadotropin-releasing hormone (GnRH) neurons. IGSF10 knockdown both in vitro and in a transgenic zebrafish model resulted in perturbed GnRH neuronal migration. Loss-of-function mutations in IGSF10 were also identified in five patients with absent puberty due to hypogonadotropic hypogonadism (HH). Additionally, I have identified and investigated one rare, pathogenic mutation in HS6ST1 - a gene known to cause HH - in one family with DP, and two rare variants in FTO - a gene implicated in the timing of menarche in the general population - in 3 families. Further potentially pathogenic variants have emerged from investigating candidate genes identified from microarray studies (LGR4, SEMA6A and NEGR1) and from related clinical phenotypes (IGSF1).

▼ Events in early life have consistently been associated with health outcomes in later life. The ‘developmental origins’ theory first hypothesised that adverse conditions in-utero can lead to physiological adaptations in the developing foetus which have long lasting influences on health. This concept has been extended to early childhood and adolescence, whereby exposures during critical periods of development can impact health throughout the life course of an individual. In particular, a secular trend for a decreasing age of puberty onset has been linked to the global increases in prevalence of cardio-metabolic diseases and cancer. It has been suggested that childhood obesity and lifetime sex hormone exposure may act as key mediating factors in this relationship. As the prevalence of obesity continues to rise globally and consequent comorbidities place an increasing burden on healthcare systems, understanding the mechanisms that link early life events to later life health have become of increasing importance. While environmental exposures are often cited as being highly influential on growth and development, the role of genetics has become gradually more apparent in recent years. This has been aided by the availability of increasingly large data resources. Genetic studies have shown that many developmental traits are highly heritable and share genetic determinants with metabolic and reproductive health outcomes. In this thesis I use data from large-scale, population-based resources to further elucidate the role of genetic and epigenetic factors in explaining observed associations between developmental traits and later life metabolic and reproductive health. I begin by examining the genetic aetiology of puberty timing in men, a key stage of sexual development which is understudied compared to women. I identify 29 novel genes involved in the control of puberty timing, implicating new biological pathways and demonstrate genetic correlations between earlier age of puberty and adverse health in adulthood. I then expand on the theme of genetic discovery by conducting genome-wide association studies (GWAS) for reproductive traits in the UK Biobank study. These outcomes have important societal and public health impacts but many have not previously been investigated from a genetic perspective. I identify over 800 variant-trait associations, highlighting genomic regions with highly pleiotropic influences on a diverse range of reproductive traits. This data is then leveraged to construct a framework for conducting phenome-wide association studies (PheWAS), which is used to explore the extent to which both BMI and sex hormone exposure act as mediating factors to explain the link between earlier puberty and heightened reproductive health risks. I go on to examine mechanisms linking early life markers of development to adult health. I investigate the association between weight at birth and body composition in adulthood, determining that foetal and maternal-specific genetic determinants of birth weight have differential influences on…

▼ In recent years, there has been a population-level trend toward earlier puberty, which presents psychological and clinical risks to girls. Body fatness and earlier puberty are also risk factors for problems including adult obesity and breast cancer. Diet is a primary and modifiable factor that can influence puberty and growth. Current research on a Mediterranean-like dietary pattern in regard to these outcomes is limited; no studies have examined its role in puberty outcomes or longitudinal growth, and only one study has examined a Mediterranean-like diet (MD) and body mass index (BMI) in a healthy U.S. pediatric population. We aimed to address these gaps in the literature by evaluating the role of MD adherence in puberty, growth, and body fatness in The Jersey Girl Study. We developed an index for assessing adherence to a Mediterranean-like diet and evaluated its relationship with cross-sectional and longitudinal outcomes. Our sample was a cohort of 202 girls who resided in New Jersey and were 9 or 10 years old at baseline. Data were collected from a baseline study visit and physical examination, a 3-day dietary recall, a general baseline questionnaire filled out by girls’ mothers, and annual follow-up questionnaires on growth and puberty outcomes. Multivariable Poisson regression models showed that high adherence (score 6-9) was significantly associated with lower prevalence of thelarche at baseline compared to girls with low adherence (score 0-3) (Prevalence Ratio: 0.65, 95% confidence interval (CI): 0.48-0.90 in the fully adjusted model). Further analysis suggested that this may have been driven by consumption of fish and reduced/low/non-fat dairy. Multivariable linear regression models to examine mean age at thelarche also suggested a nonsignificant trend of later age at thelarche with higher MD adherence. Multivariable Cox proportional hazards models found that girls with higher MD adherence had significantly longer time to menarche (Hazard Ratio: 0.45, 95% CI: 0.28-0.71 in the fully adjusted model for girls with high vs. low MD adherence). Further analysis suggested that this relationship was driven by vegetable and reduced/low/non-fat dairy consumption. Multivariable proportional odds models for being overweight or obese at baseline, and multivariable linear regression models comparing mean BMI z-score, percent body fat, waist circumference, waist-to-hip ratio, waist-to-height ratio, height at baseline, and height at menarche, did not show a significant relationship with MD adherence in this study. Multivariable linear mixed-effects growth models also did not show a difference in pubertal growth rate based on MD adherence. The results of our study were consistent with previous findings that certain components of a Mediterranean-like diet were associated with a later age at menarche and thelarche. To our knowledge, this is the first study to demonstrate an association between an overall MD pattern and puberty outcomes. Our results suggest that consuming a more Mediterranean-like diet (high in plant-based… Advisors/Committee Members: Bandera, Elisa V (chair), Barrett, Emily S (internal member), LIN, YONG (internal member), Parekh, Niyati (outside member), School of Graduate Studies.

▼ Puberty in boys has long been an under-investigated area of research mainly due to the lack of an easily available pubertal marker, corresponding to menarche for girls. Using a unique, large, population-based cohort, this thesis targets some of the knowledge gaps regarding puberty and BMI change during puberty in boys. We collected information on height and weight throughout childhood until young adulthood for all included subjects from archived school health records and from the military conscription register, into the BMI Epidemiology study (BEST) cohort. Using these measurements, we estimated prepubertal childhood BMI, post pubertal young adult BMI, BMI change during puberty, and age at Peak Height Velocity (PHV) an objective assessment of pubertal timing. Through linkage with the Cause of Death register we obtained cause of death for all subjects. Childhood BMI and the prevalence of overweight and obesity among 8-year-old boys have overall increased substantially since birth year 1946 until birth year 2006. However, after a significant increase in BMI starting in the 1970s and with a peak at birth year 1991, we observed a moderate but significant decrease (Paper I). Furthermore, we have demonstrated that childhood BMI was inversely associated with pubertal timing in normal weight but not in overweight boys (Paper II). Age at PHV displayed a clear secular trend towards earlier puberty among boys. Since the 1940s until birth year 1996, the pubertal growth spurt was 1.5 months earlier per decade, and this trend could only slightly be explained by the coinciding increase in childhood BMI (Paper III). We demonstrated that BMI change during puberty, but not childhood BMI, was independently associated with the risk of adult cardiovascular mortality. This association between BMI change during puberty and cardiovascular mortality was non-linear, with 22% increased risk of cardiovascular mortality per additional increase in BMI units for individuals in the highest quartile. (Paper IV). This unique material has enabled us to identify long-term trends of childhood BMI and pubertal timing, and to identify a large BMI increase during puberty as a novel independent risk marker for increased risk of adult cardiovascular mortality. The results from this thesis have the potential to transmit directly into benefits for the society through adjustments of the school health care program for improved identification of individuals at risk.

▼ Developmental changes within the hypothalamus are necessary for maturation of the reproductive neuroendocrine axis. Recent reports have implicated several neuronal networks in this process, but genes involved in their regulation have not been elucidated. Using a well-established model for nutritional induction of precocious puberty, objectives were to 1) use microarray technology to examine changes in gene expression within the arcuate nucleus (ARC) of the hypothalamus in pre-pubertal heifers fed high or low-concentrate diets, and 2) determine if high-concentrate diets are required for nutritional induction of precocious puberty. In Experiment 1, early-weaned, cross-bred heifers were fed either a high-forage/low-gain (HF/LG; 0.45 kg/d) or a highconcentrate/ high-gain (HC/HG; 0.91 kg/d) diet for 91 d. Analysis of microarray data indicated that 346 genes were differentially expressed (P < 0.05) between HC/HG and HF/LG heifers. Expression of three key metabolic genes [neuropeptide Y (NPY), agoutirelated protein (AGRP), and growth hormone receptor (GHR)] observed to be differentially expressed in the microarray analysis was investigated further by quantitative PCR. Real-time RT-PCR indicated that expression of NPY, AGRP and GHR was lower (P < 0.05) in HC/HG compared to HF/LG heifers. In contrast, concentrations of insulin (P < 0.05), IGF-1 (P < 0.002) and leptin (P = 0.1) were greater in HC/HG compared to HF/LG. For Experiment 2, 48 heifers were used in 2 replicates (24 heifers/replicate) in a 2 x 2 factorial design to examine the roles of diet type (HF vs HC) and rate of gain (LG, 0.45 kg/d vs HG, 0.91 kg/d) on age at puberty. Heifers were fed HC/HG, HC/LG, HF/HG or HF/LG (n = 12/group) for 14 wk, and then switched to a common growth diet (0.68 kg/d) until puberty. Heifers in both HG groups reached puberty at a younger age (54.5 ± 1.8 wk) than heifers in both LG groups (60.2 ± 1.9 wk; P < 0.04). A marked increase (P < 0.01) in serum concentrations of leptin occurred in HC/HG heifers between 24 and 30 wk of age. This increase in circulating leptin was not observed in other groups. Overall, results indicate that nutritional regulation of reproductive neuroendocrine development involves the control of NPY, AGRP and GHR expression. The abrupt increase noted for circulating leptin in heifers fed HC/HG diets, if timed and sustained appropriately, could represent an important temporal cue for activation of the neuroendocrine system and the onset of puberty.

▼ Links between nutrition and reproductive success in heifers are well established; however, achieving a high plane of nutrition is costly, and reproductive success remains uncertain, making heifer development both expensive and risky. Development could be optimized by creating nutritionally efficient strategies that manage plane of nutrition without negatively impacting reproductive success. At an average age of 340 d (209 kg) 85 heifers were randomly assigned to 1 of 3 treatments: high (H, n = 29), programmed to gain 0.92 kg/d, medium (M, n = 28), 0.45 kg/d and low (L, n = 28), 0 kg/d from d 0 to d 49 (P1). All heifers were then programmed to gain 1.36 kg/d from d 50 to d 90 (P2). Heifers were individually fed a common diet (42% cracked corn, 26% DDG, 26% alfalfa hay, and 6% molasses; 14.0% CP, 1.1 Mcal NEg/kg) at different levels to achieve programmed rates of gain. Weekly BW and blood samples were collected. Digestion was measured beginning on d 41 (P1) and on d 83 (P2). All heifers were synchronized beginning on d 90 using the Bee-Synch protocol for fixed-time AI on d 98, followed by 56 d exposure to bulls. Pregnancy rates were determined on d 154. Gain differed between treatments in P1 (P < 0.01); M- and L-fed heifers exceeded programmed gain by 0.16 and 0.37 kg/d respectively (H = 0.83, M = 0.61, L = 0.37 kg/d), and tended to differ (P = 0.07) in P2 (H = 1.31, M = 1.41, L = 1.37 kg/d). Digestion in P1 differed (P = 0.01) between heifers fed H (86.2% DM) and L (88.7% DM); no differences (P = 0.23) were observed in P2. Total ADG and input costs were different among treatments (P < 0.01). Cost of development for the M and L treatments were 10 and 23 less per heifer, respectively, than H (95.35). Body weight and number pubertal on d 90 were not different (P > 0.10). Pregnancy rates on d 260 were not different (P = 0.99) being 97, 100, and 96% for H, M, and L, respectively. Developing heifers on a lower plane of nutrition decreased cost per pregnancy without apparent negative effects on reproductive success. The L strategy was the optimal development program based on cost per pregnancy; however, additional research is needed to confirm the effects on reproductive outcomes. With various strategies being viable options in terms of successfully achieving pregnancy, it is often difficult to determine which is the best decision, economically, for a specific operation. A heuristic approach can easily be applied, subconsciously, to making managerial decisions of an operation, potentially leading to increased error in decision making. Therefore, a decision tool was developed comparing five different development programs. Programs were compared using net cost per pregnancy (CPP) to determine the optimal strategy, based on rational decisions, that would likely prove more consistent over time. A sensitivity analysis was conducted to evaluate the extent to which each variable accounted for impacted the CPP. Cost at weaning was observed as the most influential factor when selecting an optimal program, followed by other losses… Advisors/Committee Members: Wickersham, Tryon A (advisor), Sawyer, Jason E (advisor), Cardoso, Rodolfo C (committee member), Anderson, David P (committee member).

▼ Accelerated body weight gain during the juvenile period leads to early maturation of the reproductive neuroendocrine system and puberty by advancing the onset of high-frequency release of gonadotropin-releasing hormone (GnRH). In a series of studies conducted as part of this dissertation, it was hypothesized that nutritional regimens that accelerate pubertal development alter the function of kisspeptin and neuropeptide Y (NPY) neurons, known modulators of the release of GnRH. In addition, alterations in the pattern of methylation of target genome sequences were investigated in DNA collected from the arcuate nucleus, a hypothalamic region well-characterized for its role in mediating the metabolic control of reproductive function. Early-weaned crossbred heifers were fed diets to promote an average daily gain of 0.5 Kg (Low Gain; n=12) or 1.0 Kg (High Gain; n=12) from approximately 4 to 8 mo of age. This nutritional regimen has been demonstrated to facilitate early onset of puberty in heifers. At eight mo of age, heifers were slaughtered and a block of tissue containing the preoptic area and hypothalamus was collected and processed for examining the expression of NPY and KISS1, investigating the innervation of GnRH and kisspeptin neurons by NPY fibers, and characterizing the methylation profile of target genomic DNA sequences isolated from the arcuate nucleus. Mean body weight and circulating concentrations of leptin were greater in High-gain than in Low-gain heifers. Elevated rate of body weight gain was associated with reduced expression of NPY in the arcuate nucleus, reduced proportion of GnRH neurons in apposition to NPY-containing varicosities, particularly in GnRH neurons located in the mediobasal hypothalamus, and a reduced number of KISS1-expressing cells in the mid portion of the arcuate nucleus. The rate of body weight gain during the juvenile period did not affect NPY innervation of kisspeptin neurons. Differential methylation of target genomic DNA sequences isolated from the arcuate nucleus was observed in association with rate of body weight gain in juvenile heifers, and genes affected included GHR, IGF2, IGF1R, LEPR, PEG3, LIN28B and HMGA2. Overall, results from these studies support the hypothesis that accelerated body weight gain during the juvenile period promotes alterations in cellular functions within the hypothalamus that facilitate early onset of puberty in heifers.

▼ BACKGROUND In girls, puberty is accompanied by the adolescent growth spurt, a large influx of oestrogen, as well as an increased risk of sustaining a non-contact anterior cruciate ligament (ACL) rupture. The rapid growth and hormonal changes experienced by girls throughout puberty are thought to play a role in this increased injury risk, contributing to altered lower limb inertial properties, ultimately affecting lower limb flexibility and strength, with the potential to influence landing biomechanics. However, the longitudinal changes in musculoskeletal structure and function, as well as oestrogen levels, in addition to the longitudinal development of landing technique throughout the adolescent growth spurt in girls, remains unclear. THESIS AIM The primary purpose of this thesis was to investigate the longitudinal changes in musculoskeletal structure and function, as well as the oestrogen levels, during the adolescent growth spurt in girls and the influence of these changes on lower limb landing biomechanics. METHODS Forty-six healthy girls, aged 10-13 years, were recruited for this longitudinal study based on their pubertal development (Tanner Stage II-III) and their time from peak height velocity (maturity offset; -6 to -4 months or 0 months). Participants were tested up to four times during the 12 months of their adolescent growth spurt, according to their maturity offset (Test 1: maturity offset = -6 to -4 months, Test 2: maturity offset = 0 months, Test 3: maturity offset = +4 months, Test 4: maturity offset = +8 months). During the laboratory test sessions, each participant’s anthropometric characteristics, oestrogen levels, anterior knee joint laxity, lower limb flexibility, isokinetic strength and landing biomechanics were collected and recorded. The landing task performed was a horizontal leap movement, during which ground reaction forces (1,000 Hz), lower limb electromyography (1,000 Hz) and kinematic data (100 Hz) were collected. Monthly tracking was also conducted, so as to estimate maturity offset using anthropometric data, as well as to determine monthly fluctuations in lower limb flexibility and strength. Results from this longitudinal study were analysed and presented in four chapters (Chapter 3-6), with each chapter systematically contributing to the overall thesis aim. The primary purpose of Chapter 3 was to determine the longitudinal changes in anthropometry, anterior knee joint laxity, lower limb flexibility and strength, as well as the oestrogen levels, in pubescent girls during their growth spurt. Based on the findings from Chapter 3, the effects of variations in hamstring muscle strength (Chapter 4) and anterior knee joint laxity (Chapter 5) on the lower limb landing biomechanics of these pubescent girls were investigated. Finally, based on the longitudinal musculoskeletal changes displayed by girls in Chapter 3, the final experimental chapter of this thesis investigated the longitudinal changes in lower limb landing technique displayed by pubescent girls through their…

▼ This study sought to gain a more thorough understanding of male and female African lion (Panthera leo) reproductive biology through non-invasive means. Compared to other felids housed in captivity, lions historically bred well. However, a 6-year period of low fecundity in the U.S. population was observed after the cessation of a breeding moratorium, so the North American African lion Species Survival Plan (SSP) requested assistance in identifying the cause. Additionally, wild lion populations are declining rapidly; thus, maintaining captive insurance populations and developing assisted reproductive technologies may be required to maintain genetic diversity and preserve the species. However, there is a dearth of basic information on lion reproductive biology, including puberty onset and the impact of stress on reproductive function, which led to this biomedical survey of animals of varying ages and reproductive success within the captive population. Twenty six males from 18 zoos ranging in age from < 1 mo – 16.0 yr, and 38 females from 19 zoos, ranging in age from < 1 mo – 13.8 yr, were included in this study. Gonadal and adrenal steroid hormone metabolites were monitored in feces collected from 20 males and 28 females, body weights measurements were obtained ~monthly from 11 males and 17 females, and urine samples were collected from six males for spermaturia evaluation. Specific objectives of this study were to: 1) utilize non-invasive hormone monitoring to identify age and seasonal changes in gonadal and adrenal activity; 2) assess hormonal fluctuations related to reproductive events, such as pregnancy and estrus, to characterize reproductive life history stages; 3) examine puberty onset using variation in hormone concentrations, reproductive events and body weight measurements in females, and changes in hormone concentrations, body weight and urinary sperm in males; and 4) obtain hormonal substantiation of contraceptive effects in female lions. There was an increase in fecal androgen metabolite concentrations (FAM) at 2.0 yr of age, indicating a shift from peripubertal to subadult androgen production. While subadults had similar FAM to adult males, they had not reached a full adult weight. Puberty occurred at an earlier age in captive than wild male lions; urinalysis for the presence of spermatozoa showed positive results in 83% of samples collected from males as young as 1.2 yr. Growth rates, based on body weight measurements, also was faster in captive individuals than wild counterparts. For females, longitudinal hormonal assessments showed that there were few age-related and no seasonality-related changes in ovarian steroid production after 0.9 yr. Based on fecal estrogen metabolites (FEM), 95% percent of individuals not treated with contraception were cycling normally; estrous cycle length averaged 17.5 ± 0.4 d, estrus was 4.4 ± 0.2 d and silent estrus was observed in 82% of females where behavioral observations were available. Pregnant luteal phases averaged 109.5 ± 1.0 d, while non-pregnant luteal phases… Advisors/Committee Members: Birchard, Geoffrey (advisor).

▼ Background: Accumulating evidence suggests puberty is occurring earlier today than ever before. Pubertal timing may be a harbinger for abnormal metabolic health. Thus, identifying its upstream determinants and downstream metabolic health consequences may provide an avenue to primordial prevention. The objective of this dissertation was to investigate pubertal timing in relation to type 2 diabetes (T2D), adipose depots, non-alcoholic fatty liver disease (NAFLD), and early-life nutrition. Methods: This dissertation includes three separate but related research manuscripts. The first aimed to investigate pubertal timing and T2D in a Brazilian adult population (35-74y) who were born and came of age before the rise of overweight and obesity in Brazil. The second examined pubertal timing in relation NAFLD and fat depots in a biracial cohort of young adults (18-30 years at entry, 42-56 years at measurement of NAFLD) from the Coronary Artery Risk Development In Young Adults (CARDIA) study. Finally, the third paper determined the role of diet quality and risk of early pubertal timing in a biracial sample of girls (9-10 years) from the National Heart, Lung, and Blood Institute Growth and Health Study (NGHS). Multivariable linear regression was used for continuous outcomes (glucose homeostasis measures, adipose depots, liver attenuation, and age at menarche) and Poisson regression to generate prevalence ratios (PR) and relative risks (RR) for dichotomous outcomes (T2D, NAFLD, and early menarche). In the last project, a diet quality score, derived by summing standard deviation scores for the densities of nutrients/chemicals indicative of prudent or Western dietary patterns, was analyzed in relation to incident early menarche. Results: In the first paper: early menarche [<11 years vs. 13-14 years (reference)] was associated with 22% (95% confidence interval: 3-42%) higher prevalence of T2D in Brazilian adults, adjusted for confounders and BMI at age 20 years. In the same model, a 1-standard deviation higher relative leg length (RLL), a marker of early life growth and maturation, was associated with a 10% (5-15%) and 11% (7-15%) lower prevalence of T2D in women and men, respectively. The association between RLL and T2D was stronger among females with earlier menarche (p for interaction on multiplicative scale = 0.02), and among adults who were overweight or obese at age 20 years (p for interaction on multiplicative scale = 0.02) or 35-74 years (p for interaction on multiplicative scale = 0.03). In the second paper: in CARDIA, a 1-year increment in age at menarche was associated with 10% (2-18%) lower prevalence of NAFLD, and inversely associated with visceral, subcutaneous, and intra-abdominal muscle fat, after adjusting for confounders and BMI measured at 18-30 years. RLL was also associated with these measures, but was attenuated after control for BMI. Lastly, in the third paper: a better diet quality was associated with lower risk of early menarche (<11 years) after adjustment for confounders and % body fat from skinfolds…

▼ Introduction: Pesticides are toxic substances that can also cause unintended adverse effects, e.g., endocrine disruption, in exposed non-target populations such as humans. Some endocrine disrupting compounds (EDCs) (e.g., the organochlorine pesticide dichlorodiphenyltrichloroethane (DDT)) are identified as persistent organic pollutants while other suspected EDCs (e.g., atrazine) are less persistent in the body. A trend towards early puberty in girls has been observed in the United States and Europe. This decline in the age of onset of puberty has been associated with several factors including exposures to EDCs. The endocrine disrupting effects due to population exposures to pesticides are still not well understood. Objectives: 1) To characterize the in utero exposure of girls in the Avon Longitudinal Study on Parents and Children (ALSPAC) in Bristol, United Kingdom (UK) to organochlorine pesticides and examine the association with early menarche 2) To characterize the in utero exposure of girls in ALSPAC to atrazine pesticide and examine the association with early menarche. Methods: Exposure to 9 organochlorine compounds and 7 atrazine analytes measured in maternal serum or urine collected during pregnancy was characterized using non-parametric survival analysis methods. Logistic regression methods were used to examine the association between in utero exposure to these pesticides and early menarche. Results: Hexacholorbenzene (HCB), β-hexacholorocyclohexane (β-HCH), 2,2-Bis(4-chlorophenyl)-1,1,1-trichloroethane (p,p’-DDT) and 2,2-Bis(4-chlorophenyl)-1,1-dichloroethene (p,p’-DDE) were detected in more than 50% of the study participants. Diaminochlorotriazine (DACT) was the only atrazine analyte detected in more than 50% of the study participants. Overall, there was no association between in utero exposure to organochlorines and early menarche. In utero exposure to higher levels of the atrazine metabolite DACT in the ALSPAC cohort was associated with an increased odds of early menarche. Conclusions: More emphasis needs to be placed on measuring exposure in countries where organochlorine pesticides are still in use and evaluating their associations with adverse health effects. Our results suggest an association between in utero exposure to the atrazine metabolite DACT and early menarche in the ALSPAC cohort. To accurately assess atrazine exposure in populations, several metabolites including DACT need to be measured.
