All mice were approved by the Laboratory Animal Welfare Ethics committee at Harbin Institute of Technology (Approval No: IACUC- 2024138) and conducted in accordance with the Guide for Care and Use of Laboratory Animals and the institutional ethical guidelines for animal experiments

On the other hand, PERK induces translation initiation factor eIF2 phosphorylation ( NTZ has been reported to modulate UPR signaling, promoting antioxidant defenses, suppressing inflammatory cytokines, inhibiting PDI, and ultimately preventing cell injury ( Indeed, NTZ and its active circulating metabolite tizoxanide directly protect from stress-induced apoptosis and necroptosis to alleviate liver damage in acute-on-chronic liver failure rat model ( Apoe / mice ( In our attempt to scrutinize the hepatoprotective potential of NTZ and the possible implication of ER stress inhibition in our model of MTX-induced hepatotoxicity, we compared NTZ effects to a hepatoprotective NAC with documented ER stress inhibition and with a standard ER stress inhibitor (4-PBA) ( 5 Conclusion Collectively, it can be concluded that MTX-induced hepatotoxicity is mediated, at least in part, through ER stress, which was confirmed by the reversal of MTX toxicity upon administration of 4-PBA and NAC
Protein extraction, solubilization and quantification Total protein was extracted from summer leaf samples as described by Faurobert et al., (2007)
We next conducted the same experiments using THP-1 cells, a human monocyte-derived macrophage model, and showed that KL1 similarly enhanced antibiotic killing in human macrophages (Fig
