Figure 4. pc-DNA-GDF15 significantly inhibited the ferroptosis in OGD/R-treated H9C2 cells. (A, B) The Fe²⁺ level in cells were validated (bar: 100 μm, magnification: 100×); (C, D) The relative expression intensity of GPX4 in the cells were evaluated (bar: 200 μm, magnification: 40×); (E, F) The levels of GSH and MDA in the cells were measured. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001.
