The Claim

In rat tissue homogenates, aminopeptidases, serine proteases, and metalloproteases are likely involved in the degradation of exendin-4, based on the observed inhibitory effects of bestatin, PMSF, and phenanthroline on peptide breakdown in vitro.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In rat tissues, certain enzymes probably break down a peptide called exendin-4, and scientists saw that blocking those enzymes slowed the breakdown in lab tests.

See the scientific wording

In rat tissue homogenates, aminopeptidases, serine proteases, and metalloproteases are likely involved in the degradation of exendin-4, as suggested by the inhibitory effects of bestatin, PMSF, and phenanthroline on peptide breakdown in vitro.

What the research says

1 study
  1. Study: In Vitro Metabolic Stability of Exendin-4: Pharmacokinetics and Identification of Cleavage Products

    The study tested the same substances mentioned in the claim and found they slow down the breakdown of exendin-4 in rat tissues, which supports the idea that those enzymes are involved.
