Abstract

To study the effects of the anthocyanin single component cyanidin-3-O-glucoside (Cy-3-glu) on the proliferation and migration of mouse melanoma cells and to elucidate the underlying mechanisms, B16-F10 cells were treated with different concentrations of Cy-3-glu. Cell viability was analyzed by a CCK-8 method. Cell migration was determined by the callus scratching technique. Cell cycle was measured by the flow cytometry. The expression levels of genes involved in cell cycle regulation were detected by real-time PCR. Protein expression levels of p-AKT, E-cadherin, N-cadherin and vimentin were analyzed by Western blot. The growth and migration of B16-F10 cells in C57BL/6J mice were monitored by the cryogenically cooled IVIS-imaging system. The results showed that Cy-3-glu significantly inhibited the growth (P < 0.001) and migration (P < 0.01) of B16-F10 cells, and arrested the cell cycle in the S phase. After Cy-3-glu treatment, the expression levels of p-AKT (P < 0.05), N-cadherin and vimentin (P < 0.001) were decreased significantly, and the expression level of E-cadherin was dramatically increased (P < 0.05). The size and weight of tumors and tumor metastasis in mice fed with a diet containing Cy-3-glu were significantly reduced (P < 0.05). In conclusion, Cy-3-glu inhibits proliferation and migration of B16-F10 cells by inhibiting the PI3K/AKT signaling pathway, cell adhesion and migration signals.
