一般說明

Gastrin, a classic digestive hormone, is found in three major forms: gastrin-34 (big gastrin), gastrin-17 (little gastrin), and gastrin-13 (minigastrin). Mammalian gastrin consists of a C-terminal four amino-acid sequence and a sulfated tyrosine 7 residue from the C-terminus. Gastrin is mostly found in the G cells of the stomach mucosa. Nutrients and gastrin-releasing peptides stimulate the release of gastrin.

應用

Gastrin I (1-14) has been used:
  • as a component of gastric cancer stem/progenitor cell (GCSPC) medium for tumorsphere culture
  • as a supplement in organoid growth medium (OGM) for patient-derived organoid (PDO)
  • in viable lymphocytes culture for re-stimulation assay

生化／生理作用

Gastrin is a linear polypeptide that induces the secretion of gastric acid (HCl) by parietal cells.
The peptide gastrin I (1-14), which lacks a basic site, forms positive ions. Gastrin promotes the production and liberation of histamine in enterochromaffin-like cells through cholecystokinin 2 receptor (CCK2R). It also stimulates the release of gastric acid in parietal cells via the CCK2R receptor. Gastrin plays a key role in Zollinger-Ellison syndrome. It may play a role in the development of colorectal carcinoma.

Negative ion production from peptides and proteins was investigated by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Although most research on peptide and protein identification with ionization by MALDI has involved the detection of positive ions, for some acidic peptides

Tumor progression relies heavily on the interaction between the neoplastic epithelial cells and their surrounding stromal partners. This cell cross-talk affects stromal development, and ultimately the heterogeneity impacts drug efflux and efficacy. To mimic this evolving paradigm, we have micro-engineered
