Fig 3. Effect of protease inhibitors on exendin-4 degradation.

Fig 3

Inhibition of exendin-4 degradation was measured in rat (a) kidney and (b) liver pre-treated with the indicated protease inhibitor. The amount of peptide remaining was assayed after 30 min (kidney) or 60 min (liver). The results are expressed as the percentage inhibition of exendin-4 degradation. n = 3; *, P < 0.05 compared to the control group.
