Sulfated-Oxysterol and Oxysterol Sulfation by Hydroxysterol Sulfotransferase Promote Lipid Homeostasis and Liver Tissue Regeneration
Methods and compositions for the prevention and treatment of liver damage or disease in a subject in need thereof are provided. The methods involve providing the sulfated oxysterol 25-hydroxycholesterol-3-sulfate (25HC3S) to the subject e.g. by 1) administering 25HC3S to the subject; or 2) overexpressing, in the subject, the hydroxysterol sulfotransferase enzyme SULT2B1b, which catalyzes the sulfation of 25-hydroxycholesterol (25HC) to form 25HC3S.
