MAP1LC3B and hepatocellular carcinoma: IF and Western blot results showed that LC3B, a canonical marker of cell autophagy (30, 31), was substantially enhanced in Huh7 and HepG2 cells on CAP exposure, whereas that of LO2 cells was unaffected (Figures 1C, D), suggestive of a selective induction of autophagy in HCC cells as compared with normal liver cells.
