How to use

In Vitro:

Urocortin, rat induces cyclic AMP (cAMP) generation with EC50 of 0.15 nM, 0.063 nM, and 0.087 nM for human CRF1, rat CRF2α and mouse CRF2β, respectively in stably transfected Chinese hamster ovary cells.

In Vivo:

Urocortin, rat (0.01 to 10 μg) decreases food intake in both food-deprived and non-deprived rats and such an effect also observed in mice after 1 μg of Urocortin, rat i.c.v. administration. Urocortin, rat has the potential of inducing anxiogenic behavior.
