Hydrogen alleviates right ventricular hypertrophy by inhibiting ferroptosis via restoration of the Nrf2/HO-1 signaling pathway

Figure 4 Hydrogen inhalation alleviated iron a^fumulation in monocrotaline-treated rats. A: Representative images of Prussian blue staining. Magnification is 20 ×. Scale bar = 50 µm; B: Quantification of Prussian blue iron staining; n = 4; C: Right ventricular Fe content; n = 6. Data are expressed as the mean ± SD. ^aP < 0.05 and ^cP < 0.01: MCT group vs control group; ^bP < 0.05 and ^dP < 0.01: MCT+ H₂ group vs MCT group. MCT: Monocrotaline; H₂: Hydrogen.
