Aims
Cyclophosphamide (CP) is a common therapeutic drug for cancer, but exposure to CP can cause acute hepatotoxicity. This study aimed to elucidate the protective effects of Ligustrazine (2, 3, 5, 6-tetramethylpyrazine, TMP) on hepatotoxicity induced by CP or its active metabolite 4-hydroperoxycyclophosphamide (4-HC). Main
Methods
We presented a comprehensive investigation about the hepatoprotection of TMP on CP-induced mice and 4-HC-treated HSC-LX2 cells. Liver function was detected via enzyme-linked immunosorbent assay (ELISA). Hepatic histopathology analysis was performed via hematoxylin and eosin (H&E) and Masson staining. Survival of hepatocytes was detected by TUNEL assay. Related proteins in the thioredoxin (Trx)-interacting protein (Txnip)/Trx/Nuclear factor-kappa B (NF-κB) pathway were measured by western blotting. Key findings: The
Significance
TMP treatment could significantly alleviate the hepatotoxicity process as evidenced by improving the structure and function of the liver, inhibiting oxidative stress and inflammation accompanied with pyroptosis, which was positively correlated with the inhibition of Txnip/Trx/NF-κB pathway.
