Figure 9. CDKN2A enhances colorectal cancer cell viability and migration through suppressing cuproptosis. (A) Western blot analysis was performed to examine the expression changes of FDX1 in HT-29 and HCT116 cells following knockdown of CDKN2A and addition of a cuproptosis inhibitor (*P<0.05, **P<0.01, ***P<0.001). (B) The CCK8 assay was utilized to assess alterations in cell proliferation ability in HT-29 and HCT116 cells upon CDKN2A knockdown and cuproptosis inhibitor treatment (*P <0.05, **P <0.01, ***P <0.001). (C) Transwell assay was employed to evaluate changes in cell invasion ability in HT-29 and HCT116 cell lines following CDKN2A knockdown and cuproptosis inhibitor supplementation (*P <0.05, ** P <0.01, *** P <0.001).
