Sphingosine Kinases/Sphingosine 1-Phosphate Signaling in Hepatic Lipid Metabolism.

Current pharmacology reports

Kwong EK, Li X, Hylemon PB, Zhou H.
PMID: 29130028
Curr Pharmacol Rep. 2017 Aug;3:176-183. doi: 10.1007/s40495-017-0093-2. Epub 2017 Jun 20.

The ever-increasing prevalence of metabolic diseases such as dyslipidemia and diabetes in the western world continues to be of great public health concern. Biologically active sphingolipids, such as sphingosine 1-phosphate (S1P) and ceramide, are important regulators of lipid metabolism....

OBJECTIVE: Altered bacterial composition is associated with disease progression in cirrhosis but the role of virome, especially phages, is unclear.DESIGN: Cross-sectional and pre/post rifaximin cohorts were enrolled. Cross-sectional: controls and cirrhotic outpatients (compensated, on lactulose (Cirr-L), on rifaximin (Cirr-LR))...

Bile acids as global regulators of hepatic nutrient metabolism.

Liver research

Hylemon PB, Takabe K, Dozmorov M, Nagahashi M, Zhou H.
PMID: 29123941
Liver Res. 2017 Jun;1(1):10-16. doi: 10.1016/j.livres.2017.03.002. Epub 2017 Apr 26.

Bile acids (BA) are synthesized from cholesterol in the liver. They are essential for promotion of the absorption of lipids, cholesterol, and lipid-soluble vitamins from the intestines. BAs are hormones that regulate nutrient metabolism by activating nuclear receptors (farnesoid...

Rifaximin Exerts Beneficial Effects Independent of its Ability to Alter Microbiota Composition.

Clinical and translational gastroenterology

Kang DJ, Kakiyama G, Betrapally NS, Herzog J, Nittono H, Hylemon PB, Zhou H, Carroll I, Yang J, Gillevet PM, Jiao C, Takei H, Pandak WM, Iida T, Heuman DM, Fan S, Fiehn O, Kurosawa T, Sikaroodi M, Sartor RB, Bajaj JS.
PMID: 27560928
Clin Transl Gastroenterol. 2016 Aug 25;7(8):e187. doi: 10.1038/ctg.2016.44.

OBJECTIVES: Rifaximin has clinical benefits in minimal hepatic encephalopathy (MHE) but the mechanism of action is unclear. The antibiotic-dependent and -independent effects of rifaximin need to be elucidated in the setting of MHE-associated microbiota. To assess the action of...

25-Hydroxycholesterol 3-sulfate is an endogenous ligand of DNA methyltransferases in hepatocytes.

Journal of lipid research

Wang Y, Lin W, Brown JE, Chen L, Pandak WM, Hylemon PB, Ren S.

J Lipid Res. 2021;62:100063. doi: 10.1016/j.jlr.2021.100063. Epub 2021 Mar 08.

The oxysterol sulfate, 25-hydroxycholesterol 3-sulfate (25HC3S), has been shown to play an important role in lipid metabolism, inflammatory response, and cell survival. However, the mechanism(s) of its function in global regulation is unknown. The current study investigates the molecular...

Hepatic Branch Vagotomy Modulates the Gut-Liver-Brain Axis in Murine Cirrhosis.

Frontiers in physiology
