通过检测正常和转化的大鼠气管上皮(RTE)细胞对生长因子的需求和生长因子及其受体的表达,探讨多肽生长因子在大鼠气管上皮(RTE)细胞多阶段癌变过程中的作用。与原代培养的RTE细胞相比,转化的RTE细胞株对牛脑垂体提取物、胰岛素和表皮生长因子的需求减少。有数据表明,在转化的RTE细胞中,在转化的RTE细胞中,在存在转化生长因子α抗血清和转化生长因子α/EGF受体激酶抑制剂的情况下,转化生长因子α的产生和增殖减少,提示转化生长因子α在转化的RTE细胞中具有自分泌作用。因此,转化的RTE细胞对EGF需求量的减少可以通过自分泌转化生长因子α的调节来解释。相反,在转化的RTE细胞中没有检测到胰岛素/IGF-I自分泌途径的证据。这些数据表明,在转化的RTE细胞中,生长因子途径发生了多种变化。
The role of peptide growth factors in the process of multistage carcinogenesis of rat tracheal epithelial (RTE) cells was assessed by examining growth factor requirements and expression of growth factors and their receptors in normal and transformed RTE cells. Transformed RTE cell lines show decreased requirements for bovine pituitary extract, insulin and epidermal growth factor compared to primary RTE cells in culture. An autocrine role for TGF alpha in transformed RTE cells is suggested by data showing TGF alpha production and decreased proliferation in the presence of TGF alpha antisera and TGF alpha/EGF receptor kinase inhibitor. Therefore, decreased EGF requirements in transformed RTE cells could be explained by autocrine TGF alpha regulation. In contrast, no evidence for an insulin/IGF-I autocrine pathway could be detected in transformed RTE cells. These data indicate that multiple alterations in growth factor pathways occur in transformed RTE cells.
