The Claim

In anaesthetized pigs, the addition of the nine-amino acid COOH-terminal extension from exendin-4 to GLP-1 increases its plasma half-life from 4.8±3.3 minutes to 19.5±3.3 minutes, indicating that this structural modification significantly reduces clearance and enhances the metabolic stability of GLP-1 in this animal model.

Source: The C-terminal extension of exendin-4 provides additional metabolic stability when added to GLP-1, while there is minimal effect of truncating exendin-4 in anaesthetized pigs.

In plain English

In pigs under anesthesia, adding a small piece from a lizard hormone to a blood sugar hormone makes it last much longer in the body.

What the research says

1 study

  1. Study: The C-terminal extension of exendin-4 provides additional metabolic stability when added to GLP-1, while there is minimal effect of truncating exendin-4 in anaesthetized pigs.

    The study shows that adding a small piece from a longer hormone to GLP-1 makes it last much longer in pigs, just like the claim says.
