›FIELD

The present embodiments provide methods, compounds, and compositions useful for inhibiting hydroxysteroid 17-beta dehydrogenase 13 (LOC345275; 17-beta hydroxysteroid dehydrogenase; HSD17B13; HSD17013) expression, and in certain instances, reducing the amount of HSD17B13 protein in a cell or animal, which can be useful for treating, preventing, or ameliorating a disease associated with HSD17B13.

›BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) covers a spectrum of liver disease from steatosis to nonalcoholic steatohepatitis (NASH) and cirrhosis. NAFLD is defined as fat accumulation in the liver exceeding 5% by weight, in the absence of significant alcohol consumption, steatogenic medication, or hereditary disorders (Kotronen et al, Arterioscler Thromb. Vasc. Biol. 2008, 28: 27-38).

Non-alcoholic steatohepatitis (NASH) is NAFLD with signs of inflammation and hepatic injury. NASH is defined histologically by macrovesicular steatosis, hepatocellular ballooning, and lobular inflammatory infiltrates (Sanyal, Hepatol. Res. 2011. 41: 670-4). NASH is estimated to affect 2-3% of the general population. In the presence of other pathologies, such as obesity or diabetes, the estimated prevalence increases to 7% and 62% respectively (Hashimoto et al, J. Gastroenterol. 2011. 46(1): 63-69).
