RCOR1 and hepatocellular carcinoma: CCK-8 and EDU assays were used to characterize RCOR1 effects on HCC cell proliferation, knockdown of RCOR1 can significantly inhibit cell viability compared with siRNA-negative control (NC) group (Figures 10A, C), whereas upregulation of RCOR1 raised cell viability (Figures 10B, D).
