doi: 10.3892/mmr.2026.13802

Figure Lengend Snippet: Abnormal expression of antioxidant and iron metabolism-related proteins in liver samples of rats with chronic cholestasis. Control group was fed a chow diet, whereas the ANIT and DFO-treated groups were intragastrically administered ANIT olive oil solution with or without DFO (n=8/group). (A) Changes in ferroptosis antioxidant-related protein expression. The blots shown are representative of three independent experiments. A dotted line indicates that the lanes were non-adjacent on the original gel. All target protein bands and their corresponding loading control bands shown side-by-side were derived from the same membrane. Relative expression levels of (B) Nrf2, (C) Keap1, (D) XCT, (E) HO-1 and (F) GPX4. (G) Changes in iron metabolism-related protein expression. The blots shown are representative of three independent experiments. A dotted line indicates that the lanes were non-adjacent on the original gel. All target protein bands and their corresponding loading control bands shown side-by-side were derived from the same membrane. Relative expression levels of (H) TFR1, (I) FPN1, (J) DMT1, (K) Steap3 and (L) FTH1. Data are presented as the mean ± SD. P-values were determined by one-way ANOVA. *P<0.05, **P<0.01, ***P<0.001.

Schematic illustration of W-POM NCs inhibiting ferroptosis by modulating the S100A8/ A9-mediated iron metabolism pathway. The nanoclusters targeted oxidative stress and iron dysregulation to manage ICH, demonstrating their potential for neuroprotection and therapeutic efficacy.
