生长抑素(somatostatin,SST)是一种由D细胞分泌的环状多肽类激素,它对生长激素、胰岛素、促胃液素等多种内外分泌激素有强大的抑制作用。近年许多研究显示SST有抑制肿瘤增殖、诱导肿瘤细胞调亡的功能,这在结肠癌、乳腺癌等多种肿瘤的研究上已得到证实,其生物学效应是通过靶细胞
Somatostatin (SST) is a cyclic peptide hormone secreted by D cells, which has a strong inhibitory effect on many kinds of exocrine hormone such as growth hormone, insulin and gastrin. In recent years, many studies have shown that SST has the function of inhibiting tumor proliferation and inducing the apoptosis of tumor cells, which has been confirmed in the study of many cancers such as colon cancer and breast cancer. The biological effect is through the target cells
