Abstract:
We investigated the effects of adrenomedullin on rat mesangial cell proliferation. Adrenomedullin (10(-10)-10(-7) M inhibited both [3H]thymidine incorporation into cultured rat mesangial cells and cell proliferation in a concentration-dependent manner. Adrenomedullin (10(-10)-10(-6) M) stimulated cyclic adenosine monophosphate accumulation in rat mesangial cells in a concentration-dependent manner. These findings suggest that adrenomedullin inhibits proliferation of rat mesangial cells probably through a cyclic adenosine monophosphate-dependent mechanism.
