Fig. 4From: Effect of nicastrin on hepatocellular carcinoma proliferation and apoptosis through PI3K/AKT signalling pathway modulationRegulation of cell proliferation by NCSTN in liver cancer cells. a, b Western blotting showing PCNA protein expression in HepG2 and Sk-hep1 cells. c, d Cell proliferation was detected with a 5-ethynyl-2-deoxyuridine (EdU) assay in HCC cells after NCSTN silencing. e Cell proliferation ability was detected by colony formation assay. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
