Fig. 5: Effect of KIAA1429 on regulating the expression of SIRT1.

A, B SW480 and HCT116 cells were infected with scr and KIAA1429 shRNA, the mRNA and protein level of SIRTs were detected by QRT-PCR (A) and western blotting (B). **P < 0.01. C, D SW480 and HCT116 cells were transfected with empty vector (EV) and KIAA1429 plasmid, the mRNA and protein level of SIRTs were detected by QRT-PCR (C) and western blotting (D). **P < 0.01. E The proliferation of SW480 and HCT116 cells after KIAA1429 depletion followed with or without SIRT1 overexpression was measured using CCK- 8 assay. *P < 0.05. F The growth of SW480 and HCT116 cells over 14 days after KIAA1429 depletion followed with or without SIRT1 overexpression was measured using colony formation assay.
