Furthermore, the expression of PD-L1 on the surface of HCC cells was measured, revealing that overexpression of IGF2BP1 enhanced the expression of PD-L1 on the cellular surface of HCC cells, whereas silencing IGF2BP1 led to a reduction in PD-L1 surface expression (Figures 3F, G). This evidence concerns the gene IGF2BP1 and hepatocellular carcinoma.
