anti-Gastrin (GAST) Antibodies

Human Gastrin (GAST) interaction partners

1. feedback between the level of ghrelin and gastrin in the blood of patients with chronic gastritis and type 2 diabetes mellitus; with increasing levels of gastrin in the blood, the level of ghrelin in the blood decreases and vice versa

2. The same markers were also expressed in a proportion of adenocarcinomas supporting the view that gastrin is important in the development of gastric cancer

3. We concluded that low serum gastrin is related to increased risk of ER(+) BC development. The results also established that CCKBR/ERK/P65 signaling function is generally tumor suppressive in ER(+) BC, indicating therapies should focus on restoring, not inhibiting, CCKBR/ERK/P65 pathway activity.

4. Study reveals that Galphas binds to RGS1 and plays a necessary role during RGS1mediated promotion of melanoma proliferation and migration.

5. Gastrin and BCL2 apoptosis regulator (Bcl2) are highly expressed in gastric cancer tissues, and they are correlated with the clinicopathologic features.

6. Everolimus down-regulates the systemic levels of gastrin and glucagon in patients with pancreatic neuroendocrine tumors.

7. we suggest that gastrin contributes to the emergence of MDR of SGC7901 cells via the degradation of p27Kip1

8. Results demonstrate that gastrin increases the expression of the autophagy markers MAP1LC3B-II and SQSTM1 in gastric adenocarcinoma cells. Gastrin induces autophagy via activation of the STK11-PRKAA2-ULK1 and that this signaling pathway is involved in increased migration and cell survival.

9. PTHLH is a gastrin-regulated growth factor that might contribute to gastric epithelial cell homeostasis.

10. Gastrin is expressed in both insulin(+) and somatostatin(+) cells in adults with type 2 diabetes.

11. Gastrin induced ABCG2 expression by activating NF-kappaB and thereby modulated the side population proportion, tumor cell metastatic potential and invasion activity in pancreatic cancer.

12. CTGF is overexpressed in gastric cancer and adjacent tissue compared to normal gastric tissue. Gastrin induces expression of CTGF in gastric epithelial cells.

13. Data show that 6 of 20 primary pancreatic neuroendocrine tumors (PNETs) had positive staining for multiple hormones gastrin, insulin, glucagon, and somatostatin, and positive expression of 1 or more hormones was found in 9 of 12 nonfunctioning PNETs [NF-PNETs]) patients.

14. Gastrin role in gastric epithelial homeostasis and gastric carcinogenesis

15. Results suggest a role for Toll-like receptor 4 in gastric acid regulation and that the Toll-like receptor 4 (TLR4) +896 and +1196 wild type homozygozity increases peptic ulcer risk via gastrin secretion.

16. Serum pepsinogens I (PGI) and II (PGII), gastrin 17 (G-17), and antibodies against whole H. pylori, or cytotoxin-associated gene A (CagA) antigen among 309 consecutive patients, were measured.[Pepsinogen I, Gastrin 17]

17. treatment with gastrin, a CCK2R agonist, stimulated the secretion of GLP-1, and that this effect was likely due to increased expression of proglucagon and PCSK1 (also known as prohormone convertase 3 (PC3 gene)).

18. Gastrin stimulates MMP-1 expression in gastric epithelial cells and stimulates cell migration.

19. Progastrin is a new pro-angiogenic factor in colorectal cancer and an attractive therapeutic target.

20. Small (

Mouse (Murine) Gastrin (GAST) interaction partners

1. Gastrin induces nuclear export and proteasome degradation of menin in duodenal glial cells.

2. PTHLH is a gastrin-regulated growth factor that might contribute to gastric epithelial cell homeostasis.

3. Renal-selective silencing of Gast by the renal subcapsular injection of Gast siRNA in BALB/c mice decreases renal dopamine production and increases blood pressure.

4. Gastrin is expressed in insulin secreting cells of adult diabetic mice.

5. CTGF is overexpressed in gastric cancer and adjacent tissue compared to normal gastric tissue. Gastrin induces expression of CTGF in gastric epithelial cells.

6. increased circulating concentrations of progastrin provide a physiological advantage against systemic hypoxia in mice

7. Ihh signaling mediates gastrin-induced proliferation of epithelial cells in stomachs of adult mice.

8. mouse corneal afferent sensory neurons expressed CCK and GAST, and the CCK1R receptors.

9. Data indicate that epithelial Gli2 expression was sufficient to stimulate Il-1beta expression, repress Gast gene expression and increase proliferation, leading to antral hyperplasia.

10. gastrins play an important direct role, unrelated to their ability to stimulate acid secretion, in hematopoiesis under conditions of iron deficiency.

11. Initiation of antral gastric cancer is associated with progressive epigenetic silencing of TFF1, which can be suppressed by the hormone gastrin.

12. Regulation of mouse gastrin gene in vivo. Mechanisms involved in transcriptional control of the gastrin gene.

13. RegI and gastrin may synergistically regulate gastric mucosal proliferation during certain pathological settings like wound healing

14. To examine the importance of gastrin or its receptors during development in general and for gastric physiology specifically both have been knocked out.

15. stimulates the growth of gastric pit cell precursors by inducing its own receptors.

16. Endocrine gastrin may have a role in the colonic adenoma carcinoma sequence. Hyper-gastrinaemia may promote proliferation of human colonic adenomas that express CCK-2 receptor isoforms.

17. Parietal cells were found to be significantly smaller in the mutant cell preparations, suggesting that gastrin stimulation modulates parietal cell morphology.

18. essential physiologic role for gastrin in glucose homeostasis; however, the gastrin gene is not essential for murine islet development or the adaptive islet proliferative response to beta-cell injury.

19. Lack of gastrin impairs gastrin-enterochromaffin-like cell axis, whereas lack of gastrin and CCK impairs both hormonal pathways. In gastrin-CCK double-knockout mice, acid secretion is controlled by cholinergic vagal stimulation, normalizing acid output.

20. Cis-acting element mediating gastrin responsiveness was mapped to the -69 to -58 region of the HB-EGF promoter. Gastrin stimulation was PKC dependent and at least partially mediated by activation of the EGF receptor.

Guinea Pig Gastrin (GAST) interaction partners

1. Serum gastrin decreased significantly in the cholesterol gallstone groups compared to the control group.
