Abstract

Background: Obesity is a cause of FGF21 resistance, which affects the browning and thermogenesis process of the adipose tissue. Decreased receptor expression is influenced by miR-34a, whose expression is increased in obesity. While FGF21-based therapies have been widely investigated, the potential activity of Hibiscus sabdariffa Linn. extract (HSE) against FGF21 resistance is unknown. Objective: This study aims to determine the effects of HSE on the expression of miR-34a and FGF21 receptors in white adipose tissue. Methods: This experimental study used 24 male Sprague-Dawley rats and divided into four groups: Control (N); diet-induced-obesity rats (DIO); DIO rats with HSE 200 mg/kgBW/day and DIO rats with HSE 400 mg/kgBW/day. Rats were fed a high-fat diet for 17 weeks. HSE was administered daily for 5 weeks. The administration of HSE 400 mg/kgBW/day resulted in the equivalent expression of miR-34a to that of the control (p > 0.05). Results: FGFR1 receptor expression was also similar to controls (p > 0.05). Beta-klotho expression was significantly lower than that of control (p < 0.05) but equivalent to that of DIO rats (p < 0.05). Conclusions: H. sabdariffa has the potential to reduce FGF21 resistance in DIO rats through the suppression of miR-34a expression and an increase in the number of FGFR1 and beta-klotho receptors in adipose tissue.
