Using quantitative RT-PCR array, we measured the expression levels of 84 key genes involved in the mechanisms behind type 2 diabetes mellitus (T2DM) in adipose tissue (the full list of genes is presented in Table 1, and list of genes grouped by function is provided in Table 2) in BNL CL.2 cells in the presence or absence of resistin (25 ng/ml for 24 hours) (Fig. 1). Here, RETN is linked to type 2 diabetes mellitus.
