FAS and colitis: Consistent with unchanged level of TG content in the liver, the hepatic expressions of genes related to fatty acid uptake including LDLR, FATP2 and FATP5 (Fig 3E), and lipogenic genes including PPARɣ, SREBP1c, ACC, FAS, SCD1, GPAT, and DGATs were not changed or rather decreased in FMT-colitis mice compared to FMT controls (Fig 3F).
