报告内容简介🕴🏼：
COUP-TFII expression is shown to be elevated in prostate cancer patients and its expression correlates with poor prognosis. In my presentation, I will show that PTEN/AKT signaling activates ETS family of transcription factor to regulate the expression of COUP-TFII and COUP-TFII is a major factor mediating PTEN/AKT signaling to induce tumor growth. It is also shown that the expression of COUP-TFII is further enhanced in patients with metastatic prostate cancer. COUP-TFII over-expression suppresses SMAD4/TGF signaling to disrupt the growth barrier induced by SMAD4 in the PTEN null mutant and further augments tumor metastasis. COUP-TFII, being a member of nuclear receptor superfamily, its activity could potentially be regulated by ligands. Thus, COUP-TFII could be an excellent therapeutic target for cancer intervention.
