Figure Lengend Snippet: HBV-miR-3 expression leads to hepatocyte cholesterol build-up. A: Experimental design of the fluorometric cholesterol estimation assay performed for evaluating the expected increase in intracellular cholesterol post HBV-miR-3 expression in hepatocytes. B: Cellular cholesterol levels in cells (Huh7, HepG2) 48h after transfection with pHBV-miR-3, pcDNA3.1+, HBV 1.3x and microRNA-Scramble control (miR-SC). The cholesterol levels were normalised to respective total protein content. Bar graphs represent mean (±SD) of three independent experiments. C: Left panel: Hepatic lipid droplet accumulation visualised by BODIPY 493/503 staining in cells (Huh7, HepG2) 48 h post transfection with pHBV-miR-3 and pcDNA3.1+. The cells were counterstained with nuclear stain DAPI. Scale bar: 20 μM. Right panel: Quantitative analysis of BODIPY 493/503 fluorescence intensity was quantified in each micrograph and expressed as the mean ± standard errors (n = 6) in arbitrary units (a.u). ∗ P ≤ 0.05.
Article Snippet: The second aliquot was subjected to lipid extraction as described earlier ( ) followed by estimation of total cellular cholesterol content using the Amplex red cholesterol fluorometric assay kit (ThermoFisher Scientific).
