Since high levels of serum ferritin are associated with lower HMW levels of adiponectin in people with type 2 diabetes (24), we measured percent unmodified adiponectin, which is considered a proxy of HMW adiponectin (17), and has been shown to discriminate between dolphins with high iron load versus healthy controls at a 2 h post-prandial time point. The gene discussed is ADIPOQ; the disease is type 2 diabetes mellitus.
