Fig. 3: Knockdown of FOXP3 inhibited the proliferation of GBM cell via inducing ferroptosis in vivo.

A, B Subcutaneous tumor formation assay was used to detect whether FOXP3 regulated U87 cell proliferation in vivo via a ferroptosis mechanism. C The weight of tumor tissues derived from U87 cells with FOXP3-knockdown or combined treatment with Fer-1. D The in situ tumor formation model was used to detect whether FOXP3 regulated U87 cell proliferation in vivo via a ferroptosis mechanism. E The expression of FOXP3, KI67, PCNA and GPX4 was detected in tumor tissues derived from U87 cells with FOXP3-knockdown or combined treatment with Fer-1 by IHC method. **P < 0.01.
