Estrogen regulates PDPK1 to promote cell proliferation in epithelial ovarian cancer.

ABSTRACT: Epithelial ovarian cancer (EOC) is a common estrogen-sensitive tumor that poses a serious threat to women 's health, and the mortality rate of EOC ranks first among malignant tumors in females. Studies have indicated a strong link between estrogen abnormality and EOC progression. We accidently found that 3-phosphoinositide-dependent protein kinase-1 (PDPK1) is highly expressed in EOC tissues. Further, estrogen also up-regulates the expression of PDPK1 in EOC cells. Notably, the expression of PDPK1 is controlled strictly, and its expression can determine the fate of cells. However, to date, the molecular mechanism by which estrogen elicits PDPK1 expression in EOC cells, and the role of PDPK1 in estrogen-driven EOC cells are not well defined. In this research, we found that a high expression
