General description

Pituitary adenylate cyclase activating polypeptide-38 (PACAP38) is mapped to human chromosome 18. 27-residue-amidated fragment (PACAP27) comprises another isoform. The PACAP38 is major isoform associated with mammals.

Application

Pituitary adenylate cyclase activating polypeptide-38 has been used to test its effect in stimulating the formation of cyclic AMP hypothalamus and cerebral cortex slices of chicken and to treat glioblastoma cells (U87MG) in cell migration assay to test its anti-invasive effects.

Biochem/physiol Actions

Pituitary adenylate cyclase activating polypeptide-38 (PACAP38) is a cardioprotectant and may help in treating radiation-induced heart disease (RIHD). It plays a protective role during oxidative stress in cardiomyocytes. PACAP38 has antioxidant, anti-apoptotic and anti-inflammatory property. It is implicated in the pathophysiology of migraine and cluster headache.
PACAP-38 is a neuropeptide that has substantial sequence homology to vasoactive intestinal peptide (VIP). It is reported to serve as a neuronal survival factor.

Activation of the trigeminal-autonomic reflex, involving the trigeminal ganglion, the superior salivatory nucleus and the sphenopalatine ganglion (SPG) is crucial in the pathophysiology of cluster headache (CH). Since pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38) is present both in the SPG and

The concentration of pituitary adenylyl cyclase-activating polypeptide [PACAP-(1-38)] in porcine adrenal glands amounted to 14 +/- 3 pmol/g tissue. PACAP immunoreactive (PACAP-IR) fibers innervated adrenal chromaffin cells (often co-localized with choline acetyltransferase). Subcapsular fibers traversed the cortex-innervating endocrine cells and

Peripheral nerve damage often results in the development of chronic pain states, resistant to classical analgesics. Since vasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) are up-regulated in dorsal root ganglion cells following peripheral nerve injury, we investigated
