Galanin has numerous effects on gastrointestinal motility in different species; however, its cellular basis of action in mediating these effects is unclear. Dispersed gastric smooth muscle cells have been shown to possess high-affinity galanin receptors that increase cAMP and cause relaxation. Recent studies show some smooth muscle relaxants such as VIP(More)
Growth hormone (GH) is used or is being evaluated for efficacy in treatment of short stature, aspects of aging, cardiac disorders, Crohn's disease, and short bowel syndrome. Therefore, we synthesized several stable growth hormone-releasing factor (GRF) analogues that could be therapeutically useful. One potent analog, [D-Ala(2),Aib(8, 18,)Ala(9, 15, 16, 22,(More)
Bombesin (BN)-related peptides, such as gastrin-releasing peptide (GRP), have been shown in vivo to stimulate release of pepsinogen. However, whether this is due to a direct interaction with chief cells is not clear. To clarify this we prepared isolated chief cells (> 90% pure) from guinea pig stomach. BN, GRP, or neuromedin B (NMB), at concentrations up to(More)
