IER5 Promotes Ovarian Cancer Cell Proliferation and Peritoneal Dissemination.

ABSTRACT: Background/Objective: Ovarian cancer (OC) is one of the most lethal gynecological cancers, having a worldwide mortality rate of 66% in 2020. The overall 5-year relative survival rate is only 21% for distant stages, due to the lack of early diagnosis. Epithelial OC, the most common high-grade serous carcinoma, carries p53 mutations in most cases. However, we found that the immediate early response 5 gene (IER5), a p53 target gene, is overexpressed in ovarian cancer cells. The molecular mechanism underlying the role of IER5 in OC has not been well studied. We previously reported that IER5 promotes the dephosphorylation and activation of heat shock factor-1 (HSF1), the master regulator of proteostasis, which induces heat shock protein (HSP) expression.
