Pid overload induced incomparably harmful effect on cell viability. PubMed ID: The amount of practical cells noticeably reduced to under 50 in a time-dependent method (p < 0.001) (Figure 1C). These data indicate that HepG2 cells undergo significant lipotoxic change under FFAs 1 mM for 24 h with about 50 decreased amount of viable cells as compared to the safety of AC extract treatment and the cells overexposed to FFAs could be in vitro model of hepatic lipoapoptosis.Effect of AC extract on steatosisTotal RNA was isolated from HepG2 cells using a Hybrid-R kit (GeneAll, Seoul, South Korea). Following that, the cDNA was hybridized from 1 g of the total RNA with a LeGene 1st strand cDNA synthesis system (LeGene Bioscience, San Diego, CA). BBC3 (PUMA) mRNA expression level was determined by a quantitative PCR as described in the manufacturer's protocol (Life Technologies, Grand Island, NY). To analyze the results, 2-Ct values compared to the normal sample were determined with StepOne software (Life Technologies, Grand Island, NY). GAPDH was used as an endogenous control. The sequences of the forward and reverse primer were 5-CATGGCCTTCCGTGTTCCT A-3 and 5-GCGGCACGTCAGATCCA-3 for the GAPDH gene, 5- GACGACCTCAAC GCACAGTA-3 and 5- AGGAGTCCCATGATGAGATTGT-3 for the PUMA gene, respectively [26,27].Statistical analysisAll data represent at least two separate experiments and each experiment was performed in triplicate. The significance of the data was analyzed with Prism 5 software with one-way ANOVA and Bonferroni's posthoc test to compare each set of data. Bars show the means ?SEMs. *, p < 0.05; **, p < 0.01; ***, p < 0.001.In order to observe hepatic lipid accumulation, HepG2 cells were exposed to FFAs 1 mM, the mixture with two fatty acids which co-incubation can lead to steatogenesis and apoptosis simultaneously in hepatocytes. In other words, this FFAs organization with OA and PA 2:1 enables fat contents to be maximized and minimizes cellular damage induced by lipid overload tolerating some degree of apoptosis [25]. After culturing with FFAs 1 mM for 24 h in media containing 1 BSA, HepG2 cells were stained with Oil Red O solution for 30 min at room temperature, and then the increased intracellular lipid contents dyed pink were visually observed by microscope (?00) (Figure 2B). This lipid deposition stained by Oil Red O was analyzed quantitatively and a bar graph to display the results confirmed the visible lipid incretion versus only 1 BSA to be statistically significant (p < 0.001). In this FFAs-induced steatosis in HepG2 cells, the high buildup of lipid droplets was ameliorated to their almost original condition after treatment of AC extract for 24 h (Figure 2C and D). Steatosis is one of hallmark properties of patients with NASH [28]. Accordingly, the significantly reduced cellular lipid level PubMed ID: in AC extract-treated team could display the prospective to the improvement of correct remedies for NASH.Jang et al. BMC Complementary and Alternative Medication 2014, 14:253 four ofFigure 1 Cell viability assay. Immediately after therapy of AC extract and FFAs 1 mM about the HepG2 cells, MTT assay was executed. AC extract was treated as one hundred, 500 and one thousand g/ml for Flavopiridol twenty-four h. AC 100 g/ml confirmed no toxicity to HepG2 cells (A). In a different way concentrated AC extracts were taken care of on HepG2 cells for twenty-four h as well as the LD50 was calculated (B). FFAs ended up treated at 1 mM focus for 1 h or 24 h. The treatment method of FFAs showed signifi.
