(A) Liver weight, (B) neutral lipids (as oil red-O [ORO] incorporation), (C) triglyceride, (D) total fatty acids, and (E) free cholesterol and cholesteryl esters in atherogenic diet-fed foz/foz mice vs. Wt with or without OCA treatment. (F) Representative liver sections showing atherogenic diet (Ath)-fed Wt mice developed mild steatosis, but foz/foz mice developed NASH and OCA had no beneficial effect (Table 1). Data are mean ± SEM (n=9-10/gp). *P<0.05 vs. genotype-matched control (treatment effect), δP<0.05 vs. treatment-matched control (genotype effect).
