CDK7 is a reliable prognostic factor and novel therapeutic target in epithelial ovarian cancer.

ABSTRACT:

Objective

Cyclin-dependent kinase 7 (CDK7) engages tumor growth by acting as a direct link between the regulation of transcription and the cell cycle. Here, we investigated the clinical significance of CDK7 expression and its potential as a therapeutic target in epithelial ovarian cancer (EOC).

Methods

CDK7 expression was examined in 436 ovarian tissues including normal to metastatic ovarian tumors using immunohistochemistry, and its clinical implications were analyzed. Furthermore, we performed in vitro and in vivo experiments using CDK7 siRNA or a covalent CDK7 inhibitor (THZ1) to elucidate the effect of CDK7 inhibition on tumorigenesis in EOC cells.

Results

The patient incidence of high CDK7 expression (CDK7^High) gradually increased from normal ovarian e
