NCAPH silencing inhibited the MEK/ERK/PD-L1 signaling pathway in ovarian cancer cells. A Western blot images showing the expression levels of p-MEK, p-ERK, PD-L1, MEK, ERK, and GAPDH in control, sh-NC, and sh-NCAPH groups. B-F Quantitative analysis of protein expression levels of p-MEK, p-ERK, PD-L1, MEK, and ERK by western blot in the three groups mentioned above. All experiments were performed in triplicate.*P < 0.05, **P < 0.01 and ***P < 0.001
