The knockdown of USP4 expression promotes melanoma cell apoptosis under cisplatin treatment. A and B, Representative flow cytometry images of cell apoptosis in A2058 cell with indicated treatment. The lower panel is the knockdown efficiency of USP4 expression. The lower panel is a densitometry analysis of 3 individual experiments. C and D, Representative flow cytometry images of cell apoptosis in 451Lu cell with indicated treatment. The lower panel is a densitometry analysis of 3 individual experiments. Data are presented as the mean ± SD, ns, non‐significant, *P < .05; Student's t test
