RESUMO
Objective: To investigate anti-dyslipidemic effects of hydroalcoholic fenugreek seed extracts, diosgenin, and 4-OH-Ile on HepG2 cell line. Methods: HepG2 cells were treated with hydroalcoholic fenugreek seed extracts, diosgenin, 4-OH-Ile, and orlistat. IC20 was calculated using the MTT method. The cells were then pre-treated with IC20 concentrations for 24 and 48 h. Real time PCR was employed to measure expression of liver X receptor alpha (LXRα), sterol regulatory element-binding protein-1C (SREBP-1C), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), fibroblast growth factor 21 (FGF21), peroxisome proliferator-activated receptor gamma (PPARγ), and low-density lipoprotein receptor (LDLR). Results: The results showed that LXRα (P=0.003, P<0.001), SREBP-1C (P<0.001, P<0.001), ACC (P=0.002, P=0.006), and FAS (P<0.001, P<0.001) were downregulated significantly, while FGF21 (P<0.001, P<0.001), PPARγ (P=0.004, P<0.001), and LDLR (P<0.001, P<0.001) were upregulated significantly in HepG2 cells treated with the IC20 of hydroalcoholic fenugreek seed extracts, diosgenin, 4-OH-Ile, and orlistat in 24 and 48 h, respectively. Conclusions: Hydroalcoholic fenugreek seed extracts, diosgenin, and 4-OH-Ile significantly modulate the expression of some important lipid metabolism related genes, which is similar to orlistat. Trigonella foenum-graecum seed extract or its derivatives should be further investigated for their dyslipidemia effects and its complications.
RESUMO
To investigate the cytotoxicity and anti-cancer effects of hydro-alcoholic extract of pistachio pericarp on hepatocellular carcinoma cells (HepG2) and mouse fibroblast L929 cells as normal and control group cell.Methods: MTT assay was performed to investigate the cytotoxicity effects of the extract at 0-4000 μg/mL on the cells after 24 and 48 h. The expressions of some genes involved in apoptosis includingBax,Bcl-2 andP53 were investigated by real time PCR.Results: Our results showed that after 24 and 48 hours of treatment of cells with this extract, the viability of HepG2 and L929 cells was reduced. Therefore, this extract had the cytotoxicity effect on both cells. The IC50 concentration of extract for HepG2 cells after 24 and 48 hours of treatment was 1500 and 1000 μg/mL and for L929 cells was 2000 and 1500 μg/mL, respectively. The expressions ofBax andP53 genes were up-regulated after treatment in the HepG2 and L929 cells and the expression ofBcl-2 gene was down-regulated after treatment of extract in HepG2 cell.Conclusions:According to the results of MTT assay and real time PCR, this extract can be considered as a potential candidate for use in the production of anti-cancer drugs for the treatment of patients with liver cancer in future.
