Fig. 2From: Metformin induces ferroptosis through the Nrf2/HO-1 signaling in lung cancerEffects of metformin on the oxidative stress in lung cancer cells. Cells were treated with different concentrations of metformin for 48 h, the intracellular ROS intensity (A, B), the MDA concentration (C), GSH concentration (D) and T-SOD concentration (E), CAT concentration (F) were determined. n = 3, *P < 0.05 compared with the control groupBack to article page
