INS and Insulin resistance: The present study also ascertained the relative expressions of peroxisome proliferator-activated receptors, alpha and gamma (PPAR-α and PPAR-γ), involved in fat storage and insulin sensitivity [17] and a series of adipocytokines, including adiponectin (ADP), leptin, lipocalin-2 (LCN2) and visfatin levels, related to insulin release and insulin resistance [18].
