Transcriptional Regulation By Dax-1 In Pluripotent And Differentiated Cells, Alexandra C. Maramba May 2015

Transcriptional Regulation By Dax-1 In Pluripotent And Differentiated Cells, Alexandra C. Maramba

Master's Theses

DAX-1, an orphan nuclear hormone receptor, acts mainly as a repressor through transcriptional protein complexes. Its unique structure and specific expression raises questions as to what its precise interactions are and how it mediates its repressive function. While it is known to play a role in sexual development and adrenal insufficiency, expression in certain types of cancer suggests additional functions and interactions. Knock in of DAX-1 into a low-DAX-1 expressing cancer cell line has been previously observed to increase apoptosis, while, inversely, down in a high-DAX-1 expressing cancer cell line shows a decrease in apoptosis. Target genes that belong to …


Examining The Role Of Dax-1 In Regulation Of Cell Proliferation In Human Breast Cells, Amy E. Scandurra Dec 2014

Examining The Role Of Dax-1 In Regulation Of Cell Proliferation In Human Breast Cells, Amy E. Scandurra

Master's Theses

DAX-1 is a member of the Nuclear Hormone Receptor superfamily and acts as a transcriptional repressor. DAX-1 plays an important role in the development of adrenal and gonadal tissues. In addition to its role in normal cell development and differentiation, DAX-1 appears to have some influence on the progression of cancer. This work aims to examine the role of DAX-1 in regulation of proliferation in breast cancer. In our study, we have expressed DAX-1 in a DAX-1 deficient breast cancer cell line as well as knocked down DAX-1 expression in normal DAX-1 positive breast cells. Through these experiments, we were …
