MSH6 and endometrial cancer: The cell proliferation and clonal formation assay indicated that the proliferation ability of endometrial cancer cells after MSH6 knockdown was significantly weaker than that of the control group (Figures 7A, C; Supplementary Figures S4A, C), while it was significantly stronger than that of the control group after overexpression of MSH6 (Figures 7B, D; Supplementary Figures S4B, D).
