Malvidin-3-galactoside from blueberry suppresses the growth and metastasis potential of hepatocellular carcinoma cell Huh-7 by regulating apoptosis and metastases pathways

Abstract

Malvidin-3-galactoside (Mv-3-gal) is the major anthocyanin monomer in blueberry anthocyanins. The compound is well-characterized by its anti-oncogenesis function in multiple organs including liver. In the current study, the mechanism driving the anti-hepatocellular carcinoma (HCC) function of Mv-3-gal was further explored by focusing on apoptosis and metastases pathways. HCC cell line Huh-7 was firstly administrated with Mv-3-gal of different concentrations and the effect of Mv-3-gal on cell proliferation, apoptosis, colony formation ability, metastasis potential as well as the activity of Akt/PTEN and MAPK pathways was assessed. The results showed that Mv-3-gal inhibited the cell proliferation and colony formation ability, induced cell cycle arrest and apoptosis in a dose-dependent manner. Regarding the metastasis potential, Mv-3-gal suppressed the migration and invasion potential of Huh-7 cells by regulating MMPs expression. Taken together, the findings highlighted the anti-HCC potent of Mv-3-gal, which was associated with the inhibition of Akt/PTEN, MAPK and MMP pathways.
