A murine cell line, Swiss 3T3, is commonly used for the study of cellular growth. The present study revealed that this cell line possesses high-affinity receptors for endothelin, a vasoactive peptide derived from vascular endothelial cells. In this cell line, endothelin potentiated DNA synthesis stimulated by platelet-derived growth factor, basic fibroblast growth factor or insulin. The endothelin concentration required for potentiating DNA synthesis in this cell line is almost the same as that reported previously in endothelin-induced vasoconstriction. Since endothelin increased intracellular calcium levels, this ion may participate in the signal transduction pathways by which endothelin induces potentiation of DNA synthesis.
一种小鼠细胞系,即瑞士3T3细胞系,常用于细胞生长研究。本研究表明,该细胞系拥有内皮素的高亲和力受体,内皮素是一种源自血管内皮细胞的血管活性肽。在该细胞系中,内皮素增强了由血小板衍生生长因子、碱性成纤维细胞生长因子或胰岛素刺激的DNA合成。在该细胞系中增强DNA合成所需的内皮素浓度与先前报道的内皮素诱导血管收缩的浓度几乎相同。由于内皮素增加了细胞内钙水平,该离子可能参与了内皮素诱导DNA合成增强的信号转导途径。
