Cinobufotalin is a main cardiac toxin in toad, it is a novel anti-HCC agent, it induces growth inhibition and apoptosis in cultured HCC cells through ceramide production. Cinobufotalin is also an effective reversal agent for the multidrug resistance of tumors, it can reverse the adriamycin-resistance in Raji/ADR cells and the expression of P-gp and MRP-1 proteins. Cinobufotalin can promote the dendritic cells(DCs) derived from peripheral blood of patients with chronic hepatitis B to mature and effectively enhance its(the DCs') capabilities, therefore the treatment of cinobufotalin may potentiate the antiviral immunity of the patients with chronic hepatitis B(CHB).

In vitro | Hepatocellular carcinoma (HCC) is a highly aggressive and lethal neoplasm with poor prognosis. The aim of this study is to investigate the anticancer activity of Cinobufotalin, a bufadienolide isolated from toad venom, in cultured HCC cells, and to study the underlying mechanisms. METHODS AND RESULTS:We found that Cinobufotalin (at nmol/L) significantly inhibited HCC cell growth and survival while inducing considerable cell apoptosis. Further, Cinobufotalin inhibited sphingosine kinase 1 (SphK1) activity and induced pro-apoptotic ceramide production. Ceramide synthase-1 small hairpin RNA (shRNA)-depletion inhibited Cinobufotalin-induced ceramide production and HCC cell apoptosis. On the other hand, the glucosylceramide synthase (GCS) inhibitor 1-phenyl-2-decanoylamino-3-morpholino-1-propanol (PDMP) facilitated Cinobufotalin-induced ceramide production and cell apoptosis. SphK1 inhibitor II (SKI-II), similar to Cinobufotalin, increased cellular ceramide level and promoted HCC cell apoptosis. Finally, we observed that Cinobufotalin inactivated Akt-S6K1 signaling in HepG2 cells, which was again inhibited by ceramide synthase-1 shRNA-depletion. CONCLUSIONS:In conclusion, the results of this study suggest that Cinobufotalin induces growth inhibition and apoptosis in cultured HCC cells through ceramide production. Cinobufotalin may be investigated as a novel anti-HCC agent. |
