Gene expression analysis of key fibrotic markers confirmed the previous finding: expression of connective tissue growth factor (Ctgf), type I and type III collagen (Col1a1, Col3a1, respectively) and transforming growth factor β (Tgfb) were elevated in mice with CDAA diet-induced NASH. The gene discussed is COL1A1; the disease is metabolic dysfunction-associated steatohepatitis.
