Non-alcoholic fatty liver disease (NAFLD) is one of the major global health issues, strongly correlated with insulin resistance, obesity and oxidative stress. The current study aimed to evaluate anti-NAFLD effects of three different extracts of Phyllanthus niruri (P. niruri). NAFLD was induced in male Sprague-Dawley rats using a special high-fat diet (HFD). A 50% methanolic extract (50% ME) exhibited the highest inhibitory effect against NAFLD progression. It significantly reduced hepatomegaly (16%) and visceral fat weight (22%), decreased NAFLD score, prevented fibrosis, and reduced serum total cholesterol (TC) (48%), low-density lipoprotein (LDL) (65%), free fatty acids (FFAs) (25%), alanine aminotransferase (ALT) (45%), alkaline phosphatase (ALP) (38%), insulin concentration (67%), homeostatic model assessment of insulin resistance (HOMA-IR) (73%), serum atherogenic ratios TC/high-density lipoprotein (HDL) (29%), LDL/HDL (66%) and (TC-HDL)/HDL (64%), hepatic content of cholesterol (43%), triglyceride (29%) and malondialdehyde (MDA) (40%) compared to a non-treated HFD group...

The antioxidant activity of genistein is associated with preventing atherosclerosis; however, the underlying mechanisms are not fully understood. In this study, human umbilical vein endothelial cells (HUVECs) were pretreated with genistein at different concentrations (10nM, 100nM and 1000nM) for 6h and then exposed to ox-LDL (50mg/L) for another 24h. Results showed that genistein restrained reactive oxygen species (ROS) and malondialdehyde (MDA) production, and ameliorated the inhibitory effect on superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and glutathione peroxidase (GPx) activity elicited by ox-LDL stimulation...

The present study was designed to investigate the protective effects of Ilex Kuding tea polysaccharides (IKTP) on high fructose (HF)-induced liver injury and vascular endothelial dysfunction in mice. IKTP were identified as acidic heteropolysaccharides by FT-IR and HPLC. Healthy male Kunming mice fed 20% fructose in drinking water for 8 consecutive weeks significantly displayed dyslipidemia, hepatic steatosis, oxidative stress and vascular endothelial dysfunction. However, continuous administration of IKTP at 200, 400 and 800 mg per kg bw in HF-fed mice could prevent the damage caused by HF-diets, especially at dosages of 400 and 800 mg per kg bw (p < 0...

Selective delivery of anticancer drugs to rapidly growing cancer cells can be achieved by taking advantage of their high receptor-mediated uptake of low-density lipoproteins (LDLs). Indeed, we have recently discovered that nanoparticles made of the squalene derivative of the anticancer agent gemcitabine (SQGem) strongly interacted with the LDLs in the human blood. In the present study, we showed both in vitro and in vivo that such interaction led to the preferential accumulation of SQGem in cancer cells (MDA-MB-231) with high LDL receptor expression...

Endothelium toxicity has been involved in early endothelial dysfunction to show the pathogenesis of multiple cardiovascular disease that shows atherosclerosis and its complications. Saturated free fatty acids are the main inducing factors of endothelial cell apoptosis and inflammatory cytokines. In humans, stearoyl-CoA desaturase 1 (SCD-1) is a restriction step to saturation to unsaturated fatty acid desaturation, which plays a beneficial role protecting endothelial cells against lipotoxicity. Δ-17 fatty acid desaturase (FAD) is a newly identified FAD which shares 55% identity at the amino acid level with SCD-1...

Studies have shown that non-alcoholic fatty liver disease (NAFLD) patients are more prone to cardiovascular disease (CVD). Zinc and selenium deficiency are common in NAFLD. But the effects of zinc and selenium co-supplementation before and/or after disease progression on CVD markers are not clear in NAFLD patients. This study aimed to compare the effects of zinc and selenium co-supplementation before and/or after disease progression on some of the CVD markers in an experimental model of NAFLD. Forty male Sprague Dawley rats (197 ± 4 g) were randomly assigned into four dietary groups: control group (C; received 9% of calorie as fat), model group (M; received 82% of calorie as fat), and supplementation before (BS) or after (AS) disease progression...
