FASN and metabolic dysfunction-associated steatohepatitis: Subsequent comparison of LIMA1 and FASn expression levels in liver samples from healthy controls and MASH patients using the Gene Expression Database (GEO) showed a significant up‐regulation of FASn mRNA expression, which was positively correlated with liver non‐alcoholic fatty liver activity score (NAS) and LIMA1 in the GSE130970 data set (r = 0.2533, p = 0.0253 and r = 0.4344, p = 0.0036, respectively) (Figure 6B–D).
