The expression of NAMPT, RALGDS, GADD45B, FOSL2, RASD1, and RTP3 did not statistically differ between NASH and simple steatosis, while the expression of PHLDA1 was higher in NASH than in simple steatosis (p-value <0.05). The gene discussed is FOSL2; the disease is metabolic dysfunction-associated steatohepatitis.
