Figure 5.Knockdown of GPX4 inhibits proliferation in thyroid cancer cells. (A) GPX4 expression levels in FTC133, K1 and TPC-1 cells by western blot analysis. (B) GPX4 expression in FTC133 cells transfected with control, NC siRNA, or siGPX4 was confirmed by western blot analysis. (C) A CCK-8 assay was used to evaluate the viability of FTC133 cells transfected with NC siRNA/siGPX4. (D) Colony formation assay demonstrated the proliferation ability of FTC133 cells transfected with NC siRNA/siGPX4. (E) Ki-67 and PCNA protein expression in FTC133 cells transfected with NC siRNA/siGPX4 under erastin treatment.
