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.
本发明提供了预防和治疗肝损伤或疾病的方法和组合物,其中方法包括向需要该方法的受试者提供
硫酸化的氧化
固醇25-羟基
胆固醇-3-
硫酸酯(25HC3S),例如通过1)向受试者注射25HC3S;或2)在受试者中过度表达羟基
固醇磺酸转移酶酶SULT2B1b,该酶催化25-羟基
胆固醇(25HC)的
硫酸化形成25HC3S。
