Abstract

Zinc finger protein 367 (ZNF367) has been documented as a new cancer-related protein that exerts a pivotal role in the carcinogenesis of multiple cancers. However, whether ZNF367 plays a role in colorectal cancer has not been fully understood. Our data showed that ZNF367 expression was higher in colorectal cancer. Depletion of ZNF367 weakened the proliferative and invasive capabilities of colorectal cancer cells. Up-regulation of ZNF367 enhanced the in vitro malignant features of colorectal cancer cells. Knockdown of ZNF367 impeded the activation of Yes-associated protein (YAP1). Reactivation of YAP1 reversed the ZNF367-knockdown-mediated anticancer effects. Suppression of YAP1 significantly abolished ZNF367-overexpression-induced tumor-promotion effects. Depletion of ZNF367 repressed the tumorigenicity of colorectal cancer cells in vivo. These findings demonstrate that ZNF367 is overexpressed in colorectal cancer and acts as a potential tumor-promoter that contributes to the proliferation and invasion of colorectal cancer by enhancing the activation of YAP1 signaling.
