We examined the percentage of RIG1 immunostained tissue compared to total tissue in all samples and detected cytoplasmic RIG1 expression (Figure 2A–C), whereby the percentage of RIG1 immunopositivity was in NASH (Figure 2C) significantly higher than in NAFL (Figure 2B), shown in boxplots (p = 0.01; Figure 2A). The gene discussed is PLAAT4; the disease is metabolic dysfunction-associated steatohepatitis.
