The targeted muscle insulin receptor knockout (MIRKO) model was used, in which there is a complete absence of the insulin-receptor signaling in skeletal muscle but normal insulin and glucose levels. By comparing skeletal muscle gene-expression profiles from MIRKO mice and their controls (lox/lox) under three different metabolic conditions (namely, in the basal state, after streptozotocin (STZ)-induced diabetes, and after STZ-induced diabetes rendered euglycemic with insulin treatment), we can address the following three important questions. (i) What is the direct effect of the loss of insulin signaling on gene expression in skeletal muscle? (ii) What is the contribution of the metabolic and other changes that accompany diabetes to induce indirect changes in gene expression? (iii) How are these pathways regulated and implicated in the pathophysiology of diabetes?
