Aging-associated impairment in metabolic compensation by subcutaneous adipose tissue promotes diet-induced fatty liver disease in mice.

ABSTRACT:

Background and aims

Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome, and its progression is associated with aging-associated impairment in metabolic homeostasis. Recently, energy metabolism in adipose tissue has been the subject of renewed interest, because significant energy expenditure can be induced in cells derived from white adipose tissue progenitors, in addition to brown adipose tissue (BAT). Here we evaluated whether aging-associated change in various adipose tissue depots affects the progression of NAFLD.

Methods

Six-week-old male C57BL/6NCrSlc mice were fed control chow (C) or high-fat diet (60% fat; HF) for 12 or 24 weeks (12w/C, 12w/HF, 24w/C and 24w/HF groups, respectively) or switched from C to HF diet at 18 weeks of ag
