A Gene Expression Signature for Insulin Resistance

ABSTRACT: Insulin resistance is a heterogeneous disorder caused by a range of genetic and environmental factors, and we hypothesise that its aetiology varies considerably between individuals. This heterogeneity provides significant challenges to the development of effective therapeutic regimes for long-term management of type 2 diabetes. We describe a novel strategy, using large-scale gene expression profiling, to develop a gene expression signature (GES) that reflects the overall state of insulin resistance in cells and patients. The GES was developed from 3T3-L1 adipocytes that were made M-bM-^@M-^\insulin resistantM-bM-^@M-^] by treatment with tumour necrosis factor (TNF-alpha and then reversed with aspirin and troglitazone (M-bM-^@M-^\re-sensitizedM-bM-^@M-^]). The GES consisted of 5 genes whose
