Anticancer effects of sodium butyrate on hepatocellular carcinoma cells in vitro.

In the present study, we investigated the anticancer effects of sodium butyrate (NaBu) on hepatocellular carcinoma (HCC) cells in vitro. As a histone deacetylase (HDAC) inhibitor, NaBu upregulated Ac-H3 and inhibited HDAC4 protein expression in a time- and dose-dependent manner. MTT assays showed that treatment with NaBu at high concentrations significantly inhibited the growth of various HCC cells.
