Knockdown of Livin (Livin–/–) in SW480 cells or HCT116 cells canceled the starvation-induced autophagy in colon cancer cells; H2A.X–/–Livin+/+ SW480 cells transfected with H2A.XWT activated autophagy induced by starvation while cells transfected with H2A.XY142F had no significant difference; Livin-H2A.XY142F axis activated autophagy in colon cancer cells through transcriptionally regulating ATG5 and ATG7. Here, BIRC7 is linked to colonic neoplasm.
