Abstract:
Vitis coignetiae Pulliat (Meoru in Korea) has been used as a folk remedy for inflammatory diseases and cancers. Our previous in vitro study suggested that anthocyanins from fruits of Vitis coignetiae Pulliat (AIMs) should have anti-cancer activities through suppression of NF-κB. Before in vivo study, we also confirmed with Hep3B human hepatocellular carcinoma cells that AIMs suppressed NF-κB-regulated gene products. Here, we investigated their effects on NF-κB-regulated gene products and cellular responses in Hep3B cell-originated tumors in athymic nude mice. Hep3B cells (1 × 106 cells/0.1 mL) were subcutaneously injected into the left flank of twelve athymic (nu/nu) male nude mice, and then the nude mice were randomly divided into two groups with six animals each. The first group of animals received intraperitoneal injection of 100 AL of 1:10 ratio of DMSO and normal saline, whereas animals of the second group received intraperitoneal injection of AIMs (5 μg/g of animal in 100 AL of 1:10 ratio of DMSO and normal saline) daily. The AIMs suppressed the tumor growth compared to control. AIMs suppressed Ki67 expression and intratumoral vessel density on immunohistochemical staining. In addition, Western blot and immunohistochemical staining revealed AIMs suppressed the NF-KB activation and NF-KB-regulated protein levels such as COX-2, XIAP, MMP-9, VEGF and ICAM which are related to cancer cell proliferation, survival, invasion and angiogenesis in Hep3B cell-originated tumors in athymic nude mice. However, the expressions of some NF-KB-regulated proteins were not significantly suppressed. Taken together, this study indicates that the AIMs have anti-cancer effects on Hep3B cell xenografts at least in part through the inhibition of NF-κB activation and downstream proteins. This study provides evidence that AIMs might have anticancer effects on human hepatocellular carcinoma.
