Abstract:

Background: Colorectal cancer (CRC) is among highest prevailing cancers in the whole world, especially in western countries. For a diverse of reasons, patients prefer naturally occurring dietary substances over synthetic agents to prevent cancer. Vicenin-2 is largely available in a medicinal plantand is an apigenin form, 6,8-di-C-glucoside, which has been reported to have a range of pharmacological values which includes antioxidant, hepatoprotective, anti-inflammatory and anti-cancer. This study was aimed to analyze the anti-proliferative effect of Vicenin-2 on human colon cancer cells via the Wnt/β-catenin signaling inhibition.

Methods: MTT assay was used to assess the cell viability at different concentrations and time point. Vicenin-2 at a concentration of 50µM (IC) decreased the phosphorylated (inactive) glycogen synthase kinase-3β, cyclin D1, and non-p-β-catenin expressions in HT-29 cells, which were evidenced through western blot analysis.

Results: Further, Vincenin-2 reduced the T-cell factor (TCF) / Leukocyte erythroid factor (LEF) reporter activity in HT-29 cells. Vicenin-2 also promoted substantial cell cycle arrest at the GM phase of HT-29 cells, as well induced apoptosis in HT-29 cells, as revealed through flow cytometric analysis. Furthermore, immunoblot analysis showed that Vicenin-2 treatment enhanced the expression of Cytochrome C, Bax and caspase-3 whereas suppressed the Bcl-2 expression.

Conclusion: Together, these results revealed that Vicenin-2 can act as a potent inhibitor of HT-29 cell proliferation and can be used as an agent against CRC.
