Potential Synergistic Effects of Caffeine and Naringin on Mitochondrial Biogenesis and Hepatic Steatosis in Adult Male Rats With NAFLD Induced by a High-Fat Diet.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide, and disturbances in lipid metabolism and mitochondrial function play a significant role in its progression. In this study, to improve the effects of caffeine (CAF) treatment, we evaluated the effects of CAF and naringin (NAR) alone and in combination on gene expression involved in mitochondrial biogenesis, plasma nonesterified fatty acid (NEFA) levels, hepatic TG levels, and pathological changes in the liver tissue in adult male rats with NAFLD induced by a high-fat diet (HFD). Then, 35 male Wistar rats were randomly assigned to five groups: control, HFD, HFD + CAF, HFD + NAR, and HFD + CAF + NAR (seven rats per group).
