Abstract

Non-alcoholic fatty liver disease (NAFLD) is a condition marked by excessive fat accumulation in the liver and poses a significant health challenge. The leaves of Blumea balsamifera and Sargassum aquifolium have been reported to have anti-atherogenic effects. This study aims to determine the effectiveness of B. balsamifera extract (BBLE) and S. aquifolium extract (SAE) in preventing and treating liver fat accumulation in Wistar rats induced by a high-cholesterol diet through the expression of the AMP-activated protein kinase (AMPK)/ Sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor γ (PPARγ) pathway, and the leptin receptor. The experimental design of this study is laboratory-based, involving, 20 Wistar rats were fed a high-cholesterol diet over a period of 21 days. The rats were divided into four groups for the evaluation of BBLE and SAE effect: negative control (P0): induced with a high-cholesterol diet + distilled water, positive control (P1): induced with a high-cholesterol diet + simvastatin, P2: induced with a high-cholesterol diet + 4 mg/kg/bw BBLE, and P3: induced with a high-cholesterol diet + 4 mg/kg/bw BBLE and 4 mg/kg/bw SAE. The treatment duration extended over three months. Immunohistochemical analyses were performed on liver tissues to measure AMPK, SIRT1, PPARγ, and leptin receptor expression. The results indicated that leptin expression was lower in the BBLE+SAE group compared to the simvastatin group, and differences were significant between the BBLE and BBLE+SAE groups. No significant differences were noted in AMPK, SIRT1, and PPARγ expression between the simvastatin and BBLE+SAE groups (p≥0.05). In conclusion, BBLE and SAE effectively reduce liver lipid accumulation and enhance fat metabolism in hypercholesterolemic rats.

Abstract

Atherosclerosis is the largest cause of mortality worldwide, and Low-Density Lipoprotein (LDL) is a primary risk factor for this illness. The purpose of this research was to determine the effect of purple sweet potato (Ipomoea batatas L.) extract on cholesterol, LDL, PCSK9, and MDA levels in rats fed a high-cholesterol diet. This true experimental study used a randomised pre-test-post-test control group design. Wistar rats were randomly assigned to three groups. Purple sweet potato extract (PSPE) was prepared by 24-hour maceration with 70% ethanol. All rats were fed a high-cholesterol diet for 14 days, followed by pre-test measurements of cholesterol, LDL, PCSK9, and MDA on day 15. Rats were then randomly divided into control (no treatment), PSPE (200 mg/day), and Simvastatin (0.9 mg/kg BW) groups. After one month of treatment, post-test analyses were performed for all parameters. The results showed an increase in serum cholesterol, LDL and MDA levels in rats fed a high-cholesterol diet (p<0.05) compared to the PSPE and Simvastatin groups. The high-cholesterol diet also resulted in a significant (p<0.05) decrease in PCSK9 when compared to the PSPE and Simvastatin groups. In the PSPE group there was a decrease in cholesterol, LDL, and MDA, and PSPE (p<0.05) compared to the control group. In the Simvastatin group, the increase in PCSK9 was very low compared to the PSPE group. PSPE has antidyslipidaemic activity by reducing total cholesterol status, LDL, and oxidative stress while promoting PCSK-9 function. Further research is still needed to provide a comprehensive understanding of the mechanism of action of PSPE as an antioxidant source in patients with atherosclerosis.
