mRNAs encoded by IL1R1 (1.99, p < 0.04), OPRM1 (2.65, p < 0.02), SIGMAR1 (3.13, p <0.03), THRB (1.94, p < 0.02) and ZFP91 (3.09, p < 0.01) genes were upregulated in gastric samples of patients with NASH as compared to those without NASH (Table 2). The gene discussed is OPRM1; the disease is metabolic dysfunction-associated steatohepatitis.
