The positive feedback between ACSL4 expression and O-GlcNAcylation contributes to the growth and survival of hepatocellular carcinoma
Figure 4. ACSL4 upregulation enhanced the stability of GLUT1 protein and reduced its ubiquitination. (A) After 12 hours of cell transfection with si-ACSL4 or OE-ACSL4, Huh-7 cells were treated with CHX (100 μg/ml) for 0, 1, 2, 4, 8 or 24 hours, and the western blotting assay was performed to detect GLUT1 expression. (B) An IP assay was used to detect the interaction between Ub and GLUT1 proteins after Huh-7 cells were transfected with si-ACSL4 or OE-ACSL4. (C) After 12 hours of cell transfection with si-ACSL4 or OE-ACSL4, SK-HEP-1 cells were treated with CHX (100 μg/ml) for 0, 1, 2, 4, 8 or 24 hours, and the western blotting assay was performed to detect GLUT1 expression. (D) IP assay was used to detect the interaction between Ub and GLUT1 protein in SK-HEP-1 cells. (*P<0.05, si-ACSL4/OE-ACSL4 group compared with control group).
