For example, the pre-heparin plasma LPL mass was found to be negatively correlated with TG concentration and insulin resistance and positively correlated with HDL-C concentration.37 Increased serum levels of adiponectin (an adipocytokine) have been found to be associated with higher HDL-C levels and lower TG38 and glucose concentrations.39 This evidence concerns the gene LPL and Insulin resistance.
