The Claim

In obese diabetic ob/ob mice, daily administration of GIP(3-42) or GLP-1(9-36)amide for 14 days resulted in no change in pancreatic insulin content, islet number, or islet morphology.

Source: Effects of sub-chronic exposure to naturally occurring N-terminally truncated metabolites of glucose-dependent insulinotrophic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), GIP(3-42) and GLP-1(9-36)amide, on insulin secretion and glucose homeostasis in ob/ob mice.

Description
1 study reviewed
In plain English

In obese diabetic mice, daily injections of GIP(3-42) or GLP-1(9-36)amide for 14 days did not alter the amount of insulin in the pancreas, the number of islets, or their structure.

See the scientific wording

In obese diabetic ob/ob mice, 14 days of daily GIP(3-42) or GLP-1(9-36)amide administration had no effect on pancreatic insulin content, islet number, or islet morphology, indicating no structural impact on beta-cell mass.

Why this might work

These hormone fragments improve how muscle, liver, and fat tissues respond to insulin, allowing the body to lower blood sugar without needing more insulin or changing the pancreas. The insulin-producing cells in the pancreas stay the same size, number, and shape because these fragments do not act on the pancreas at all.

  1. Study: Effects of sub-chronic exposure to naturally occurring N-terminally truncated metabolites of glucose-dependent insulinotrophic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), GIP(3-42) and GLP-1(9-36)amide, on insulin secretion and glucose homeostasis in ob/ob mice.

    In diabetic mice, two weeks of daily injections of these two hormone fragments didn’t change the size, number, or shape of the insulin-producing cells in the pancreas — so they didn’t make the pancreas grow or shrink in any way.
