Non-alcoholic fatty liver disease (NAFLD) is characterized by an accumulation of fat in hepatocytes, and it may progress, under additional triggering factors, to non-alcoholic steatohepatitis (NASH). Effective strategies to counteract this progression are essential, especially considering that at the moment, there is a lack of approved pharmacological therapies. Our previous study showed that the daily consumption of Navelina oranges significantly reduced hepatic steatosis in patients with Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD). Starting with our previous study, here, we have investigated the molecular targets through which Hesperidin (HE), a citrus flavanone, is able to prevent the progression of NAFLD to NASH using an in vitro model. In Hepa-RG cells exposed to NAFLD Promoting Agents, HE reduced lipid droplet accumulation (~35%) and suppressed de novo lipogenesis, with decreased expression of FASN (0.62 ± 0.06 vs. 0.39 ± 0.03 at 100 µg/mL) and SCD1 (0.05 ± 0.001 vs. 0.03 ± 0.004 at 50 µg/mL). HE also enhanced fatty acid oxidation by increasing SIRT1 (0.73 ± 0.16 vs. 2.36 ± 0.10 at 50 µg/mL) and PGC1α (0.71 ± 0.03 vs. 0.89 ± 0.003 at 50 µg/mL). In LX-2 cells, HE downregulated COL1A1 (1.48 ± 0.10 vs. 0.90 ± 0.11 at 100 µg/mL) and α-SMA (1.21 ± 0.16 vs. 0.76 ± 0.07 at 75 µg/mL) and upregulated MMP3 (0.64 ± 0.05 vs. 0.98 ± 0.07) and MMP9 (0.99 ± 0.005 vs. 2.61 ± 0.16 at 100 µg/mL). In conclusion, HE may offer a promising approach for NAFLD/NASH prevention and treatment, demonstrating in vitro its potential to reduce hepatic steatosis and fibrosis.
