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 chie

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.
