Interestingly, 4 weeks of RSV administration led to a marked decrease in angiotensinogen, renin, and AT1R expression (75.01%, 97.98%, and 63.22%, respectively) compared to that in the NAFLD group (p = 0.0002, 0.006, and 0.012, respectively; Figure 5). The gene discussed is REN; the disease is metabolic dysfunction-associated steatotic liver disease.
