一般說明

研究领域:细胞信号传导

GAST基因映射至人类染色体17q21。胃泌素是一种线性肽。它是一种胃肠激素,由胃中的 G 细胞产生。

應用

胃泌素I已用于:
  • 用胃泌素受体/胆囊收缩素受体2(CCK2R)(AGS-GR)细胞稳定转染AGS,以研究凝聚素(CLU)在人胃癌细胞中的表达和分泌
  • 作为生长培养基的组分,用于培养小鼠正常食管上皮类器官(mNEEO)
  • 作为基础培养基的补充,用于类器官培养
  • 作为分子量标记物,用于校准superdex® 30色谱柱

生化/生理作用

胃泌素在壁细胞功能、胃上皮细胞增殖和分化中起主要作用。它可作为维持和组织胃粘膜的调节剂。 它在胃中产生,并刺激胃酸分泌。胃泌素是胃肠道的重要生长因子。胃泌素与属于G蛋白偶联受体家族的胆囊收缩素B受体(CCKBR)高度亲和。它可以诱导胰腺中的胰岛细胞分化。
