Abstract: Currently, 463 million adults have diabetes and 374 million have impaired glucose tolerance. Insulin is a powerful pleiotropic hormone that affects processes such as cell growth, energy expenditure, and carbohydrate, lipid, and protein metabolism. On the other hand, skeletal muscle is the main site for insulin-dependent glucose excretion. The molecular mechanisms by which insulin regulates muscle metabolism and the underlying defects that cause insulin resistance have not been fully elucidated. The objective of this study is to perform an analysis of microarray data to find differentially expressed genes. The analysis has been based on the data of a study deposited in Gene Expression Omnibus (GEO) with identifier "GSE22309" and whose title is "Human skeletal muscle expression data". The selected data contains samples from three types of patients after taking insulin treatment: patients with diabetes (DB), patients with insulin sensitivity (IS), and patients with insulin resistance (IR). Once the 20 genes expressed differentially between the three possible comparisons were obtained (DB vs IS, DB vs IR and IS vs IR), this data set has been used to develop predictive models through Machine Learning techniques to classify patients with respect to the three categories mentioned previously. All the techniques used present an accuracy superior to 80%, reaching almost 90% when unifying the categories IR and DB.
