Transcriptional control of adipose tissue macrophages during high-fat diet-induced obesity.

ABSTRACT: We used transcriptome microarrays to identify gene expression changes in macrophages isolated from adipose tissue of lean and obese mice. Overall design: F4/80+ adipose tissue macrophages were isolated from epididymal fat of mice fed normal chow diet (NCD, lean mice) or 60% high-fat diet (HFD, obese mice) for 16 weeks.

BACKGROUND/OBJECTIVES:Obesity is a pandemic disorder that is characterized by accumulation of adipose tissue and chronic low-grade inflammation that is driven primarily by adipose tissue macrophages (ATMs). While ATM polarization from pro-(M1) to anti-(M2) inflammatory phenotype influences insulin sensitivity and energy expenditure, the mechanisms of such a switch are unclear. In the current study, we identified epigenetic pathways including microRNAs (miR) in ATMs that regulate obesity-induced  ...[more]
