胃泌素-17 最初是在猫（Felis silvestris catus）体内发现的。由于胃酸分泌与这种肽之间存在负反馈关系，胃泌素17（G-17）被认为与胃食管反流病（GERD）有关。

This Gastrin-17 was originally found in cat (Felis silvestris catus). Gastrin 17 (G-17) has been proposed to be related with GERD(gastroesophageal reflux disease), due to the negative feedback between acid secretion and this peptide.
