Abstract BackgroundEmodin (EM) is one of bioactive components extracted from Rheum palmatum L. (Dahuang), which possesses numerous pharmacological activities including hypolipidemic effect. However, the potential action of EM on hyperlipidemia (HLP) remains unclear. Here, the theraputic effect of EM against HLP were investigated.MethodsIn this study, the hypolipidemic properties of EM were evaluated using high-cholesterol diet (HCD)-stimulated zebrafish larvae model. The body weight, body length and body mass index (BMI) was measured. The total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) as well as the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected by corresponding assay kits. Tg (flil: eGFP) zebrafish were utilized to observe vascular cholesterol accumulation and Tg (mpx: eGFP) zebrafish to visualize and quantify neutrophil inflammation. The hepatic lipid deposition and hepatic histopathology were analyzed by Oil red O staining and H&E staining, respectively. Finally, the underlying mechanism of EM were investigated using real-time quantitative PCR (RT-qPCR) analysis to assess the gene levels of adenosine monophosphate-activated protein kinase alpha (AMPKα), sterol regulatory element binding protein 2 (SREBP-2), proprotein convertase subtilisin kexin 9 (PCSK9), low-density lipoprotein receptor (LDLR), 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR), adenosine triphosphate binding cassette transporter A1 (ABCA1) and adenosine triphosphate binding cassette transporter G1 (ABCG1).ResultsOur data indicated that EM reduced obesity of zebrafish as evidenced by the decrease in body weight, body length and BMI. EM significantly reduced TC, TG, and LDL-C, and increased HDL-C contents. Moreover, it displayed a prominent inhibitory effect on blood cholesterol accumulation, hepatic lipid accumulation, and neutrophil inflammation in vascular site. Additionally, EM improved the liver function through decreasing ALT and AST levels of zebrafish with HCD-induced hepatosteatosis. Further investigation showed that EM treatment attenuated lipid accumulation via upregulating the expression of AMPKα, LDLR, ABCA1 and ABCG1, and downregulating the expression of SREBP-2, PCSK9 and HMGCR.ConclusionTo conclude, EM alleviated lipid metabolism disorder symptoms caused by HCD via modulating AMPK/SREBP-2/PCSK9/LDLR pathway in larvae, suggesting that EM may be developed into hypolipidmic agent for treating lipid metabolism related diseases.

Hiperkolesterolemia adalah peningkatan kadar kolesterol di dalam darah melebihi batas yang diperlukan oleh tubuh. Penelitan ini bertujuan menguji kandungan senyawa fitokimia ekstrak etanol biji labu kuning, efek pemberian ekstrak etanol biji labu kuning dan perbedaan efek ekstrak dengan dosis bertingkat terhadap penurunan degenerasi sel beta pankreas tikus putih jantan hiperkolesterolemia diabetes. Penelitian eksperimen laboratorium ini menggunakan hewan uji sebanyak 30 ekor tikus dibagi dalam enam kelompok perlakuan. Kelompok 1 (kontrol normal) diberikan Na-CMC 0,5% dan kelompok 2 (kontrol negatif) diberi pakan tinggi kolesterol, suspensi Streptozotocin 35 mg/kgBB dan Na-CMC 0,5% b/v; kelompok 3 diberi metformin 9 mg/kgBB per oral, pakan tinggi kolesterol dan suspensi streptozotocin 35 mg/kgBB; kelompok 4, 5 dan 6 masing-masing diberikan dosis 270, 360, dan 450 mg/kgBB per oral, pakan tinggi kolesterol dan suspensi streptozotocin 35 mg/kgBB. Gambaran tingkat kerusakan histopatologi pankreas diamati dengan pewarnaan HE menggunakan mikroskop Olympus BX-51 perbesaran 200x. Hasil penelitian menunjukkan: Terdapat senyawa alkaloid, flavonoid, polifenol, saponin,dan tannin pada ekstrak etanol biji labu kuning; ekstrak etanol biji labu kuning dosis 360 dan 450 mg/kgBB efektif menurunkan degenerasi jaringan pankreas tikus hiperkolesterolemia diabetes dan pemberian ekstrak etanol biji labu kuning dosis 270 mg/kgBB tidak memberikan efek maksimal jika dibandingkan dengan dosis 360 mg/kgBB dan dosis 450 mg/kgBB terhadap regenerasi sel organ pankreas tikus putih jantan hiperkolesterolemia diabetes.   Hypercholesterolemia is an abnormal increase in blood cholesterol levels.  This study aimed to identify the phytochemical content of pumpkin seed ethanol extract, the effect of pumpkin seed ethanol extract and the difference in the effect of various doses of extract in decreasing pancreatic beta cell degeneration in male diabetic hypercholesterolemia rat. The experimental research in laboratory used 30 rats as test animals, divided into six group. Group 1 (normal control administered with 0.5% Na CMC and group 2 (negative control) administered with high cholesterol diet, Streptozotocin 35 mg/kgBWand 0.5% Na-CMC b/v; Group 3 orally administered with metformin 9 mg/kgBW, high cholesterol diet,  streptozotocin 35 mg/kgBW; group 4,5 and 6 orally administered with extract at doses of 270, 360, dan 450 mg/kgBB, high cholesterol diet,  streptozotocin 35 mg/kgBW. Histopathology examination to determine pancreas damage was observed by HE staining using microscop Olympus BX-51 200x. The results showed the presence of alkaloids, flavonoids, poliphenol, saponins,andtanninsin phumpkin seeds ethanol extract; Ethanol extract of phumpkin seeds at doses of 360 dan 450 mg/kgBW effectively decreased degeneration of pancreatic tissue of diabetic hypercholesterolemia rat and ethanol extract of phumpkin seeds at the dose of 270 mg/kgBW did not show maximum effect as compared to the doses of 360 and 450 mg/kg BE on cell regeneration of pancreatic tissue of diabetic hypercholesterolemia rat

Abstract Background Hypercholesterolemia is a major risk factor for the development of atherosclerosis and endothelial dysfunction. Methods The present study investigates the possible mechanism of Echinops spinosissimus Turra subsp. spinosus ( E. s. spinosus ) flower on the high cholesterol diet. Results Our in vitro results demonstrated the richness of E.s. spinosus flower in antioxidant compounds, and its antioxidant activities. The co-administration of E.s. spinosus (100 or 200 mg/kg/day) with high-fat diet attenuated hepatotoxicity as monitored by the improvement of oxidative stress biomarkers and plasma lipid and liver parameters, when compared to the hypercholesterolemic mice. Atherogenic index and body weight were also reduced markedly, compared to control mice. These results were confirmed by the improvement of histological changes and DNA damage. Conclusion These data indicate that E.s. spinosus flower reduces the hypercholesterolemia risk and atherogenic properties of dietary cholesterol. Its hypocholesterolemic effect may be due to its antioxidant activities and its richness in bioactive molecule.
