Article Title: Cannabis oil modulates liver alterations and endocannabinoid system changes in a female rat model of diet-induced MASLD
doi: 10.3389/fnut.2026.1770150
Figure Lengend Snippet: Liver NrF2 and NFκB p65 expression in female rats fed a reference diet (RD), sucrose-rich diet (SRD) or SRD with cannabis oil (SRD + Ca). (A) Representative photomicrographs of immunocytochemical staining NrF2 in the liver sections of rats. Decreased levels of nuclear and cytoplasmic positive markers are observed in the SRD group. Scale bar 50 μm. (B) Quantitative immunohistochemical analysis of liver NrF2 expression expressed as integrated optical density (IOD). (C) Representative photomicrographs of immunocytochemical staining NFκB p65 in the liver sections of rats. Increased levels of nuclear and cytoplasmic positive markers are observed in the SRD group. Scale bar 50 μm. (D) Quantitative immunohistochemical analysis of NFκB p65 expression in the liver. Data are expressed as mean ± SEM ( n = 6). Statistical differences were evaluated by one-way ANOVA followed by the Newman–Keuls post hoc test (* P < 0.05).
Article Snippet: The samples were incubated in a humid chamber first with a specific primary antibody for 4-HNE (mouse monoclonal antibody; Catalog # MAB3249; R&D Systems), NrF2 (mouse monoclonal antibody; sc-365949; Santa Cruz Biotechnology), NF-κB p65 (mouse monoclonal antibody; sc-8008; Santa Cruz Biotechnology) and TGF-β1 (mouse monoclonal antibody; sc-52893; Santa Cruz Biotechnology) (for 14–16 h at 4°C) and then with biotin-conjugated secondary antibody (anti-mouse, 1:100 dilution, Sigma) for 30 min at room temperature.
