This hormone's releasing factor is the human analog of bombesin, and activation of somatostatin-2 receptors on the cells that release this hormone can inhibit its release.  One form of this peptide acts upon the D cells of the antrum, and overproduction of this hormone leads to Zollinger-Ellison syndrome.  Usually secreted in the presence of calcium and amino acids, it binds to enterochromaffin-like cells and stimulates the release of histamine, and it also binds to chief cells to stimulate the

Usually secreted in the presence of calcium and amino acids, it binds to enterochromaffin-like cells and stimulates the release of histamine, and it also binds to chief cells to stimulate the release of pepsinogen.  For 10 points, name this digestive hormone secreted by G cells, which regulates the secretion of gastric acid in the stomach.
