Effects of 0–400 μM nateglinide on insulin release at 1.1 mM glucose. Following 40 min preincubation with a buffer containing 1.1 mM glucose, effects of nateglinide were tested during a 20 min incubation period. Values are mean±s.e.m. (n=6). ^*P<0.05, ^**P<0.01, ^***P<0.001 compared with the respective effect in the absence of nateglinide.
