Hyperglycemic action of synthetic C-terminal fragments of human growth hormone.
Ng. F M FM; Bornstein. J J
In rats, short pieces of human growth hormone that include the 176‑191 region cause a quick spike in blood sugar and a longer increase in insulin, and they make the animals less sensitive to insulin. Two nearby fragments (179‑191 and 180‑191) did nothing. The effect only shows up when the peptide has the right sequence and shape.
