Transcriptional Regulation By The Oncogenic Znf217/Corest Complex, Gobi Thillainadesan
Electronic Thesis and Dissertation Repository
The ZNF217 transcription factor is an oncogene found within the 20q13 amplicon and is amplified and overexpressed in many cancers including breast and ovarian. Overexpression of ZNF217 leads to increased cell proliferation, survival, and causes resistance to TGFβ's anti-proliferative effects.
ZNF217 is a core constituent of a transcriptional complex that includes CoREST, HDAC1/2, LSD1, and the CtBP1/2. In this study, I have combined genome-wide biochemical approaches to identify genes directly regulated by ZNF217. I have identified the tumor suppressor and cell cycle inhibitor, p15ink4b, as a direct target of the ZNF217 complex and demonstrated that ZNF217 represses the …
