Study of Cinobufagin as a Promising Anticancer Agent in Uveal Melanoma Through Intrinsic Apoptosis Pathway.

ABSTRACT: Uveal melanoma (UM) is the most common primary intraocular carcinoma in adults. Cinobufagin, secreted by the Asiatic toad Bufo gargarizans, is a traditional Chinese medicine, widely used in tumor treatment. Here, we explored the potential antitumor function of cinobufagin and investigated its biochemical mechanisms in UM cells. The antitumor potential of cinobufagin was determined via cell viability, cell cycle, and apoptosis assays. Colony formation assays confirmed that cinobufagin exerted potent antitumor activity in a dose-dependent manner. We found that cinobufagin could induce cell apoptosis and upregulate the expression of cleaved caspase-3, cleaved poly(ADP-ribose) polymerase (PARP), and cleaved caspase-9 in vivo and in vitro. In addition, after treatment with
