Sodium butyrate also increased cell cycle blocking protein levels (P27 and P21), as well as anti‐apoptotic protein levels (Bcl‐2 and Bcl‐xL).[109] As a result, the migration and invasion of hepatocellular carcinoma (HCC) cells was inhibited by sodium butyrate. The gene discussed is BCL2L1; the disease is hepatocellular carcinoma.
