Circ-DENND4C up-regulates TCF4 expression to modulate hepatocellular carcinoma cell proliferation and apoptosis via activating Wnt/β-catenin signal pathway.

ABSTRACT:

Background

Hepatocellular carcinoma (HCC) is a common malignant tumor in China. Advanced treatment like transcatheter hepatic arterial chemoembolization (TACE) has prolonged the lives of many HCC patients. However, the prognosis of most HCC patients remains unsatisfactory. Recently, circular RNAs (circRNAs) have been gradually unveiled to exert considerable functions in cancer. Promising circRNAs in HCC remains to be further elucidated.

Methods

Gene expression was assessed by qRT-PCR and western blot. The function of circ-DENND4C in HCC was estimated by both in vitro and in vivo experiments. The location of circ-DENND4C in HCC cells was determined by subcellular fractionation and FISH assays. The association among molecules were analyzed through RNA pull down, RIP and lucife
