Anti-obesity effects and underlying molecular mechanisms of the ethanolic extract of figs from Ficus hispida using high fat-fed wister rats

Abstract

Obesity is a known risk factor for many chronic diseases and a substantial threat to public health. We investigated the effects of figs sourced from Ficus hispida on a high fat-fed experimental rat model. We found that a 500-mg dose of ethanolic extract of figs (EFH) reduced oxidative stress markers nitric oxide (NO), malondialdehyde (MDA), and advanced oxidation protein products (AOPP), which were increased in high fat-fed rats. Antioxidant enzymes superoxide dismutase (SOD), catalase, reduced glutathione (GSH), and myeloperoxidase (MPO), found elevated in high fat-fed rats, were also normalized to nearly regular levels by fig treatment. Administration of EFH further reduced fat deposition and expression of adipogenic genes leptin, fatty acid synthase (FAS), peroxisome proliferator-activated receptor gamma (PPARγ), and sterol regulatory element-binding protein-1c (SERBP-1c). Our results suggest that figs have significant effects on reducing oxidative stress and mitigating obesity-associated liver and adipose tissue abnormalities via suppressing adipogenesis. Thus, we propose that F. hispida has potential benefits in reducing obesity.
