Figure 10 indicates that the expression of the Nrf2 protein was significantly lowered in the FFA-induced NAFLD model of HepG2 cells (p < 0.001), which further led to a sharp drop in the heme oxygenase 1 (HO-1) protein (p < 0.001). This evidence concerns the gene NFE2L2 and metabolic dysfunction-associated steatotic liver disease.
