   Achlorhydria induces G cell (gastrin-producing) hyperplasia, which leads to hypergastrinemia. Gastrin exerts a trophic effect on enterochromaffin-like cells (ECL cells are responsible for histamine secretion) and is hypothesized to be one mechanism to explain the malignant transformation of ECL cells into carcinoid tumors in AMAG.

   In addition, gastrin acts as a trophic factor for parietal cells, causing parietal cell hyperplasia. Normally, hydrogen ion secretion is controlled by a negative feedback loop by gastric cells to maintain a suitable pH, however, the neuroendocrine tumor that is present in individuals with Zollinger–Ellison Syndrome has no regulation ...
