doi: 10.3892/ijmm.2025.5492
Figure Lengend Snippet: Cur reduces autophagy-dependent ferroptosis in H9c2 cells associated with A/R injury via Sirt1. Expression of autophagy-(A) and ferroptosis-related proteins (B) in A/R-injured H9c2 cells following Cur pretreatment, Sirt1 silencing and targeted inhibition of AKT activity. (C) Relative protein expression of P62 and the ratio of LC3II/I. (D) Relative protein expression of NCOA4 and FTH1. Detection of (E) total iron ions, (F) MDA, (G) GSSG, (H) GSH, (I) GSH/GSSG and (J) SOD in A/R injured H9c2 cells following Cur pretreatment, Sirt1 silencing and targeted inhibition of AKT activity. Fluorescence intensity of (K) lysosomes, (L) ROS and (M) Fe 2+ in A/R-injured H9c2 cells following Cur pretreatment, Sirt1 silencing and targeted inhibition of AKT activity (magnification, ×200; scale bar, 400 μ m). ** P<0.05, *** P<0.01. Cur, curcumin; A/R, anoxia/reoxygenation; Sirt, silent information regulator 1; MDA, malondialdehyde; GSSG, glutathione disulfide; GSH, glutathione; SOD, superoxide dismutase; ROS, reactive oxygen species; NCOA4, nuclear receptor coactivator 4; FTH1, ferritin heavy chain 1; CON, control; si, small interfering; prot, protein; API, triciribine; LC3II, microtubule-associated protein 1 light chain 3 β; NC, non-targeting control.
