Abstract
We sought to investigate thymoquinone (TQ)/quercetin combination in preventing hepatic steatosis (HS). The included rat groups; (1) Control, (2) HS model, (3) HS treated with TQ 10 mg.kg−1.d−1, (4) HS treated with quercetin 50 mg.kg−1.d−1, and (5) HS treated with both compounds for 4 weeks. TQ/quercetin co-treatment augmented the anti-steatosis potential of each ingredient. The results revealed more (p < 0.001) sirtuin (SIRT1)/AMP-activated protein kinase (p-AMPK) upregulation compared to each treatment in line with autophagy protein Atg7 enhancement, and suppressed pro-inflammatory and oxidation markers. They diminished the hepatic lipogenic enzymes and perilipin-2 and activated the cytosolic lipases adipose triglyceride lipase (ATGL). Histological and Biochemical analysis revealed diminished lipid deposition and improved liver enzymes (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) compared to the data of separate treatments. TQ and quercitin effectively upregulated SIRT1/p-AMPK and regulated hepatic perilipin-2/ATGL, inflammation and oxidative stress, preserved liver structure and function. TQ/quercetin combination additively prevents HS. [ABSTRACT FROM AUTHOR]
