doi: 10.1186/s13287-026-04970-1

Figure Lengend Snippet: HMGB1 regulated ferroptosis to affect HSC activation and ECM deposition. A IHC assay was used to observe the expression levels of GPX4 and FTH1 in liver tissues of AHF patients. B – E The levels of Fe 2+ /Fe 3+ , ROS, GSH content and MDA in LX-2 cells treated with alcohol at different concentrations were evaluated by kit detections. ( F – G ) qRT-PCR and WB assays were employed to assess the effect of elevated alcohol concentration on the mRNA and protein levels of NRF2, GPX4, FTH1, SLC7A11 in alcohol-stimulated LX-2 cells. H – J CCK-8, EdU staining and IF assays were respectively utilized to detect the effect of Erastin on the viability, proliferation, activation and ECM deposition of alcohol-induced LX-2 cells. K The effect of Erastin on lipid peroxidation was assessed by flow cytometry using the C11-BODIPY 581/591 probe in ethanol-induced LX-2 cells. L – P The effects of Ferrostatin 1 on si-HMGB1 regulating the levels of lipid peroxidation, Fe 2+ /Fe 3+ , ROS, GSH content and MDA in alcohol-treated LX-2 cells were measured by kit detections. Q – R qRT-PCR and WB assays were used to evaluate the effects of Ferrostatin 1 on si-HMGB1 regulating the mRNA and protein levels of NRF2, GPX4, FTH1 and SLC7A11 in alcohol-stimulated LX-2 cells. S – T The effect of Ferrostatin 1 on si-HMGB1 regulating the expression of GPX4, FTH1 and HMGB1 in LX-2 cells treated with alcohol was observed by double-labeled IF assay. * p ˂ 0.05, ** p ˂ 0.01, *** p ˂ 0.001 vs. 0 µg/mL Ethanol/ Ethanol/ Ethanol + si-NC/ Ethanol + si-HMGB1

Article Snippet: Mice in the Model + sh-HMGB1 + Ferrostatin-1 group received an intraperitoneal injection of Ferrostatin-1 (1 mg/kg/d) (HY-100579, MedChemExpress, New Jersey, USA) from weeks 6 to 8, while otherwise following the same modeling protocol as described above.

Figure Lengend Snippet: sh-Hmgb1 modulated glycolytic metabolism, ferroptosis, and liver fibrosis in AHF mice. A – B H&E staining and Masson staining were used to observe the effect of sh-Hmgb1 on hepatic fibrosis in AHF mice. C – D The effects of sh-Hmgb1 on Hmgb1‌ mRNA and protein levels in liver tissue of AHF mice were assessed by qRT-PCR and WB assays. E – H Kit and IHC assays were utilized to evaluate the effect of sh-Hmgb1 on the markers related to glycolysis, ferroptosis and HSC activation. * p ˂ 0.05, ** p ˂ 0.01, *** p ˂ 0.001 vs. Normal/ Model + AAV-sh-NC
