In contrast, strategies using growth hormone-releasing factor (GRF)/growth hormone-releasing hormone (GHRH) analogues to induce physiological increases of GH and preserve the insulin-like growth factor-1 (IGF-1) negative feedback have been shown to correct metabolic abnormalities and body composition changes associated with low GH levels with fewer side effects, particularly with regard to hyperglycemia [5–8]. The gene discussed is GHRH; the disease is Hyperglycemia.
