Synbiotics Bifidobacterium infantis and milk oligosaccharides are effective in reversing cancer-prone nonalcoholic steatohepatitis using western diet-fed FXR knockout mouse models.

ABSTRACT: Milk oligosaccharides (MO) selectively increase the growth of Bifidobacterium infantis (B. infantis). This study examines the effects of bovine MO and B. infantis in preventing nonalcoholic steatohepatitis (NASH) in Western diet (WD)-fed bile acid (BA) receptor FXR (farnesoid x receptor) knockout (KO) mice. WD-fed FXR KO mice have cancer-prone NASH and reduced B. infantis. MO and/or B. infantis supplementation improved their insulin sensitivity and reduced hepatic inflammation. Additionally, B. infantis, but not MO, decreased hepatic triglyceride and cholesterol. A combination of both further reduced hepatic cholesterol, the precursor of BAs. All three treatments modulated serum and hepatic BA profile. Moreover, B. infantis and MO decreased hepatic CYP7A1 and induced Sult2a1, Sult2a2, and
