从人前列腺癌细胞系 PC-3 的无气条件培养基中纯化出用于培养的成骨细胞样细胞的肽有丝分裂原。根据氨基酸测序和估计的分子量,该肽被鉴定为尿激酶型纤溶酶原激活剂 (uPA) 的 NH2 末端片段。重组高分子量 (HMW) uPA 和 uPA 的 NH2 末端生长因子结构域 (GFD),而非低分子量 (LMW) uPA(缺少 NH2 末端区域)刺激成骨细胞样细胞中的 [3H] 胸苷掺入和增殖,并且可证明 HMW(而非 LMW)、uPA 的特异性竞争性结合位点。这些研究表明,人类前列腺癌细胞系会产生 uPA 的促有丝分裂 NH2 末端片段,这可能在成骨细胞转移的发病机制中发挥重要作用。
A peptide mitogen for cultured osteoblast-like cells was purified from aerum-free conditioned culture medium of a human prostatic cancer cell line, PC-3. Based on amino acid sequencing and estimated molecular weight, this peptide was identified as an NH2-terminal fragment of urokinase-type plasminogen activator (uPA). Recombinant high molecular weight (HMW) uPA and the NH2-terminal growth factor domain (GFD) of uPA, but not low molecular weight (LMW) uPA (lacking the NH2-terminal region) stimulated [3H]thymidine incorporation and proliferation in osteoblast-like cells, and specific, competitive binding sites for HMW, but not LMW, uPA were demonstrable. These studies demonstrate the production of a mitogenic NH2-terminal fragment of uPA by a human prostatic cancer cell line which may be of importance in the pathogenesis of osteoblastic metastases.
