2. Balikova, Anna. Studies on the functions of tumor-associated mucin-like leukosialin (CD43) in human cancer cells .
Degree: 2012, Tartu University

Subjects/Keywords: Cancer is a complex disease where cells proliferate uncontrollably and spread into different parts of the body. Unlimited division of cancer cells occurs due to activation of proteins that promote cell growth, i.e. oncoproteins, and simultaneous inactivation of proteins that regulate cell death, i.e. tumorsuppressors. Although the number of ascertained cancer-associated proteins continues to grow rapidly, the transformation of a normal cell into a tumor cell depends on changes in several key signaling pathways that regulate cell proliferation and death. Identification of tumor-associated proteins and studying their function might be applied to the elaboration of novel therapeutic strategies. In this work the functions of a potential oncoprotein leukosialin (CD43) were studied in human cancer cells. CD43 has long been regarded as a molecule present exclusively on the surface of blood cells. However, there is a growing body of evidence suggesting that CD43 might play a role in tumor development. Several studies demonstrate high level of CD43 in human solid tumor cells, including colorectal tumors, but it was not detectable in normal colon cells. Moreover, CD43 has been shown to interact with proteins that influence cell survival or proliferation. The results of the present research imply that CD43 in cooperation with the well known oncoprotein β-catenin facilitates cell growth and survival. It is believed that disorders in the functioning of β-catenin frequently lead to the formation of various types of cancer, especially colorectal cancers, since deregulated β-catenin triggers production of proteins that stimulate cell division. In cells with impaired tumorsuppressors, the increased amount of CD43, via β-catenin signaling, might cause uncontrollable proliferation of cells and initiate a tumor. However, excessive growth signals emanating from CD43 and β-catenin actuate the process of cell death, which is the main protective mechanism against tumors. Furthermore, the tumorsuppressors, in turn, decrease the level of CD43 protein. In summary, this work presents new aspects on the ability of CD43 to enhance cell growth and thereby promote tumor formation. Also, a previously undescribed negative feedback loop is proposed between CD43 and tumorsuppressors that might be important in preventing the disease.; tumor cells growth; tumor markers; molecular aspects; proteins; kasvajarakkude kasv; valgud; kasvaja markerid; molekulaaraspektid
