Atrial natriuretic factor has a weak insulinotropic action in the isolated perfused rat pancreas

Abstract
The effect of atrial natriuretic factor (ANF; 1, 10, 100, 1000 pmol/l) on insulin release from the isolated perfused rat pancreas was studied. ANF weakly augmented the glucose (10 mmol/l)-stimulated insulin release during the second (controls: 100%; 1 pmol/l: 99%; 10 pmol/l: 149%, PP<0.05). The hormone did not influence basal insulin secretion. Our data indicate an insulinotropic effect of ANF on the rat pancreas, which is dependent on the utilized background secretagogues.
