Representative pictures of ORO stained Hep3B cells ( A , B ) under 20x magnification shows accumulation of lipid droplets in cells treated with 500 μM of oleic acid, as well as significant increases in the levels of triglycerides ( C ) and free fatty acids ( D ) as compared to Vehicle ( n = 3; * p ≤ 0.05, *** p ≤ 0.001).

doi: 10.3390/jox16030076

Figure Lengend Snippet: Targeted antioxidant treatment using pNaKtide and NAC significantly reduces MC-LR-induced hepatotoxicity in Hep3B hepatocytes. Quantitative PCR analysis of markers of hepatotoxicity—SerpinE1 ( A ) and OSMR ( B ); inflammation—TNFα ( C ) and Tgf-β1 ( D ); fatty acid metabolism—CD36 ( E ) and hepatic injury—ALPL ( F ) were all significantly upregulated on treatment with MC-LR (10 µM) in the presence of oleic acid (500 µM) as compared to those in the absence of oleic acid, except for CD36, which was upregulated in the presence of MC-LR alone. These markers were significantly downregulated in cells treated with targeted antioxidants. Quantification of SERPINE1/PAI-1 protein by ELISA ( G ) in the Hep3B supernatants mirrored the genetic expression of SerpinE1 and was also reduced with antioxidant treatment; similarly, 8-OHdG ( H ), a marker of oxidative stress, followed the same trend with MC-LR causing a significant oxidative stress in the presence of oleic acid as compared to MC-LR alone, and this was reduced with antioxidant treatment.

Figure Lengend Snippet: Targeted antioxidant treatment significantly improves MC-LR metabolism in hepatocytes. Mass spectrometric-based quantification of MC-LR (green bars) and MC-LR Cysteine (yellow bars) in Hep3B cell pellet ( A ) and Hep3B cell supernatant ( B ) showed a decrease in the levels of MC-LR in cells that were treated with antioxidants as compared to the MASLD cells exposed to the toxin. On the other hand, the levels of detoxified MC-LR Cysteine were improved on treatment with antioxidants (inset to right shows MC-LR-Cysteine data on a separate scale). ( n = 3; * p ≤ 0.05, **** p ≤ 0.0001).

Figure Lengend Snippet: (A) Localization of PAL (green) at mtDNA within MitoRed ® -stained mitochondria (red) in live Hep3B cells prior to irradiation (scale bar: 10 µm, crop: 5 µm). (B) Top: snapshots of time-lapse PAL nuclear fluorescence upon WF irradiation (scale bar: 20 µm). Bottom: PAL labeling upon irradiation at distinct phases of the cell cycle ( a : interphase; b : prophase; c : prometaphase; d : metaphase; e : anaphase. Scale bar: 5 µm). Right : kinetics of PAL fluorogenesis during 5 min irradiation. Mean intensities are rescaled from 0 to 1 within a 95% confidence interval. (C) PAL nuclear fluorescence (in green) of a targeted cell islet within a population of live PAL-treated cells upon WF irradiation (PAL + hv) (R1: dotted line; R2: dashed line; NA: non-affected area. Scale bar: 50 µm). Crops in R1 (orange squares) showing stable nuclear morphology and persistence up to 9 days post-irradiation within a live-cell proliferative environment. Crops in R2 (blue squares) showing compromised nuclei. Calculated irradiation powers were 3.5 to 15 W/cm 2 in R1 from limit to center of the beam. Only evanescent or residual scattered light was present in R2 (scale bar: 20 µm). (D) Co-staining of PAL-treated cells (green) with propidium iodide (PI, red) or NucView ® 530 Red Caspase-3 dye (NucView, magenta). Top: PI stains R1 cells (dotted lines), showing a permeabilized status immediately post-irradiation (d0). After 24 h, R2 cells show important delayed PI staining demonstrating a compromised state. Bottom: NucView faintly stains R1 cells 24 h post-irradiation, showing strong signal in compromised R2 cells. The apoptosis inducer staurosporine is used as a positive control. (E) Quantification of nuclear size in different conditions: live PAL-treated cells without irradiation (PAL), FA-fixed cells (FA), PAL-free irradiated cells (hv) or PAL-treated irradiated cells (PAL + hv, R1 and R2) (n>200 per condition). Data shown in violin plots reflecting size distribution, circles indicate the medians and whiskers indicate standard deviations.
