摘要: Abstract Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) are important neuropeptides in the control of lung physiology. Both these commonly bind to specific G protein coupled receptors named VPAC 1 -R 2 -R, PAC (with higher affinity for PACAP). VIP PACAP have been implicated cell proliferation tumor growth. This study examined presence human cancer samples, as well functionality adenylyl cyclase (AC) stimulated by both peptides. Results from RT-PCR immunoblot experiments showed expression -, - samples. Immunohistochemical studies receptors. These were positively AC, but enzyme activity was impaired compared normal lung. There no changes Gα s or i levels. Present results contribute a better knowledge VIP/PACAP actions support interest development analogues with therapeutic roles.
