Epigallocatechin-3-Gallate Provides Hepatoprotection Through Endoplasmic Reticulum Stress/TXNIP/NLRP3 Axis in Paracetamol-Induced Acute Liver Injury

Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound with strong antioxidant properties and is abundantly found in green tea. We investigated how EGCG affects the liver injury of high-dose paracetamol in this study. In our study, 56 rats were divided into seven groups (n = 8): healthy control, EGCG (100 mg/kg), paracetamol (2 g/kg), paracetamol + EGCG 25 (2 g/kg + 25 mg/kg), paracetamol + EGCG 50 (2 g/kg + 50 mg/kg), paracetamol + EGCG 100 (2 g/kg + 100 mg/kg) and paracetamol + N-acetyl cysteine (NAC, 2 g/kg + 140 mg/kg). Our findings suggest that high-dose paracetamol induces liver injury through endoplasmic reticulum (ER) stress and that EGCG alleviates liver injury by attenuating ER stress-induced inflammasome signalling.
