The Claim

In anaesthetized pigs, truncation of the COOH-terminal end of exendin-4 to generate Ex(1-30) does not significantly alter its plasma half-life, which remains comparable to that of full-length exendin-4 (28.4±1.7 min vs 32.4±4.1 min), indicating minimal contribution of this region to the metabolic stability of exendin-4 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

Cutting off the end of a hormone called exendin-4 doesn’t make it break down faster in anesthetized pigs, so that part probably doesn’t matter much for how long the hormone lasts in their bodies.

See the scientific wording

In anaesthetized pigs, truncating the COOH-terminal end of exendin-4 to create Ex(1-30) has no significant effect on its half-life, which remains similar to full-length exendin-4 (28.4±1.7 min vs 32.4±4.1 min), suggesting this region contributes minimally to the metabolic stability of exendin-4 in this model.

  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 cutting off part of a hormone called exendin-4 doesn’t make it break down faster in pigs, just like the claim says.
