人结肠癌细胞系HCT 116可以在不存在外源生长因子的化学成分确定的培养基中生长。转铁蛋白和胰岛素的添加将显著刺激生长。研究了这些生长因子与其受体的相互作用,以确定胰岛素和转铁蛋白对生长的协同作用是否涉及生长因子受体的改变。转铁蛋白受体的再分布发生在转铁蛋白或转铁蛋白加胰岛素的存在下。生长培养基中胰岛素的存在导致细胞表面胰岛素受体被占据,而总胰岛素结合率不降低。此外,转铁蛋白与胰岛素导致胰岛素结合其受体的减少,而受体亲和力没有改变。转铁蛋白似乎在调节胰岛素受体中起作用,这可能有助于胰岛素和转铁蛋白对生长的协同作用。
The human colon carcinoma cell line, HCT 116, can be grown in chemically defined media in the absence of exogenous growth factors. The addition of transferrin and insulin will significantly stimulate growth. The interaction of these growth factors with their receptors was studied to determine whether the synergistic action of insulin and transferrin on growth involved alterations in the growth‐factor receptors. Redistribution of the transferrin receptor occurred in the presence of transferrin or transferrin plus insulin. The presence of insulin in the growth media resulted in occupation of cell‐surface insulin receptors without a reduction in total insulin binding. Addition of transferrin with insulin resulted in a decrease in insulin binding to its receptor, with no alteration in receptor affinity. It appears that transferrin plays a role in regulating the insulin receptor and that this may contribute to the synergistic effect of insulin and transferrin on growth.
