This study was designed to explore the protective effects of Abrus precatorius L. (Leguminosae) (AP) in HepG2 cells and N-nitrosodiethylamine (NDEA) induced hepatocellular carcinoma in Swiss albino rats. The effects of aqueous/ethanolic (50%) extract of AP on hepatic markers, haematological and histopathological parameters, and antioxidant enzymes were evaluated in NDEA ...

The present study aimed to determine the cytotoxicity of microcystin-LR (MC-LR) on the human hepatocellular carcinoma (HepG2) cells in order to elucidate the mechanism of apoptosis induced by MC-LR. Morphological evaluation results showed that MC-LR induced time- and concentration-dependent apoptosis in HepG2 cells. The biochemical assays revealed that MC-LR-exposure caused overproduction of re...

OBJECTIVE The aim of this study was to explore the effects of β3-adrenoceptor (β3-AR) activation on HepG2 cells and its influence on cholesterol efflux from macrophage foam cells. MATERIALS AND METHODS HepG2 cells were cultured and treated with the β3-AR agonist, BRL37344, and antagonist, SR52390A, and the expression of apolipoprotein (Apo) A-I, ApoA-II, ApoB, and β3-AR in the supernatants an...

Aloe vera is well-known for its pharmacological and nutritional properties. The aim of the present study was to determine the effect of A. vera gel extracts on the secretion and cell content of triglyceride (TG) and cholesterol (TC) in HepG2 cells and their short-term effects on the dietary hyperlipidemic guinea pig model. The effects of increasing concentrations of A. vera crude gel and its al...

BACKGROUND Hepatocellular carcinoma (HCC) is the most important cause of cancer-related deaths worldwide. Pirfenidone is an orally available small molecule with therapeutic potential for fibrotic diseases. MATERIAL AND METHODS In this study, we analyzed the effects of different pirfenidone concentrations on the proliferation of HepG2 HCC cells using Cell Counting Kit-8 (CCK-8) and colony format...

The effects of hepatic stellate cells (HSCs) on tumorigenicity of HCC have been previously reported. However, the detailed mechanisms responsible for these effects remain unclear. In this study, we investigated the effects of HSCs on cisplatin-induced apoptosis in human hepatoma HepG2 cell lines. HepG2 cells were treated with cisplatin alone or co-cultured with LX-2 cells 3 days before incubati...

Hexavalent chromium (Cr(VI)) is a serious environmental pollutant and human toxicant. Mammalian cells are very sensitive to chromate as they lack efficient chromate detoxifying strategy, e.g., chromate-reducing genes that are widely present in prokaryotes. To test whether introduction of prokaryotic chromate-reducing gene into mammalian cells could render higher chromate resistance, an Escheric...

Liver cancer is a progressive, irreversible and aggressive malignant disease, which has no effective chemotherapeutic drugs. RA-XII, a natural cyclopeptide isolated from the traditional Chinese medicine Rubia yunnanensis, exerts anti-cancer and anti-inflammatory activities. This work aimed to investigate the effects of RA-XII on a hepatic tumor and its underlying mechanisms in human hepatoma He...

this study was designed to explore the protective effects of abrus precatorius l. (leguminosae) (ap) in hepg2 cells and n-nitrosodiethylamine (ndea) induced hepatocellular carcinoma in swiss albino rats. the effects of aqueous/ethanolic (50%) extract of ap on hepatic markers, haematological and histopathological parameters, and antioxidant enzymes were evaluated in ndea (200 mg/kg and ccl4, 3 m...

Resveratrol is reported to possess chemotherapeutic properties in several cancers. In this study, we wanted to investigate the molecular mechanisms of resveratrol-induced cell cycle arrest and apoptosis as well as the impact of resveratrol on NAMPT and SIRT1 protein function and asked whether there are differences in hepatocarcinoma cells (HepG2, Hep3B cells) and non-cancerous primary human hep...
