Chronic Diarrhea Caused by Vasoactive Intestinal Peptide-Secreting Tumor [PDF]

Life, 2023
VIPomas are a type of neuroendocrine tumor that independently produces vasoactive intestinal peptide (VIP). VIPomas causing watery diarrhea, hypokalemia, and achlorhydria (WDHA) syndrome are not frequently observed in adult patients without pancreatic ...

Vasoactive intestinal peptide–VIPR2 signaling regulates tumor cell migration [PDF]

Frontiers in Oncology, 2022
Phosphoinositide metabolism is critically involved in human cancer cell migration and metastatic growth. The formation of lamellipodia at the leading edge of migrating cells is regulated by metabolism of the inositol phospholipid PI(4,5)P2 into PI(3,4,5 ...

Pressure-Dependent Elevation of Vasoactive Intestinal Peptide Level in Chicken Choroid [PDF]

Biology, 2023
Purpose: Autonomic control is important in maintaining ocular integrity. As recent data suggested that intrinsic choroidal neurons (ICN), an intrinsic choroidal autonomic control, may regulate choroidal thickening via release of the vasodilative ...

Immunomodulatory role of vasoactive intestinal peptide and ghrelin in Oncorhynchus mykiss [PDF]

Heliyon, 2023
Neuropeptides are a group of peptides derived from precursor proteins synthesized in neuronal and nonneuronal cells. The classical functions of neuropeptides have been extensively studied in mammals, including neuromodulation in the central nervous ...

Vasoactive intestinal peptide promotes secretory differentiation and mitigates radiation-induced intestinal injury [PDF]

Stem Cell Research & Therapy
Background Vasoactive intestinal peptide (VIP) is a neuronal peptide with prominent distribution along the enteric nervous system. While effects of VIP on intestinal motility, mucosal vasodilation, secretion, and mucosal immune cell function are well ...

Chronic diarrhea related to neuroblastoma: the important role of vasoactive intestinal peptide in tumor pathology and survival [PDF]

BMC Cancer
Background To analyze the correlation between vasoactive intestinal peptide (VIP) protein expression in neuroblastoma (NB) tumors and NB clinical features and prognosis. Methods Clinical data were collected from 91 patients with NB aged

Vasoactive intestinal peptide in canine portosystemic shunt in the absence of portal hypertension [PDF]

Open Veterinary Journal, 2021
Background: The congenital portosystemic shunt (PSS) is a common vascular anomaly in dogs. Vasoactive intestinal peptide (VIP) is produced in various organs (including the small intestine, large intestine, and pancreas), leading to abdominal vasodilation,
