The action of the regulatory neuropeptides vasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) carries out through the shared receptors VPAC1 and VPAC2 and the exclusive PACAP receptor PAC1, all of which are G protein-coupled receptors. Formerly, we showed that the administration of both peptides enhance catecholamine, corticosterone and aldosterone release from adrenal cell co-culture. Further...

Endocrine Disrupting Chemicals (EDCs) are a heterogeneous class of compounds so called for their ability to interfere with the endocrine system. These environmental pollutants are detected in different environmental matrices; they can bioaccumulate in adipose tissue and biomagnificate in food chain due to their high hydrophobicity and low water solubility1. Two EDCs usually used in the manufacture of domestic, industrial, and agricultural products are Dibutylphtalat...

The pituitary adenylate cyclase-activating polypeptide (PACAP), isolated for the first time from hypothalamic extracts (Miyata et al. 1989), was localized in some peripheral tissues such as adrenal, gastrointestinal tract, ovary and testis (Arimura et al. 1991, Watanabe et al. 1992, Gathei et al. 1993, Shioda et al. 1994, Kononen et al. 1994). It was previously demonstrated that in the testis PACAP was involved in the steroidogenesis r...
