Tumor angiogenesis has been related to the initiation as well as progression toward more aggressive behavior of human tumors. We will discuss genetic events underlying the initiation and progression of colorectal and pancreatic adenocarcinoma with a particular focus on the modulation of angiogenesis. A secreted fibroblast growth factor (FGF) binding protein (FGF-BP), which is an extracellular chaperone molecule for FGFs, has been shown to enhance FGF-mediated biochemical and biologic events and to be a crucial rate-limiting factor for tumor-dependent angiogenesis. Histochemical and in situ hybridization studies with archival samples show that FGF-BP is induced early during the initiation of colorectal and pancreatic adenocarcinoma. We will discuss the potential of this secreted protein as a serum marker to identify at-risk subjects.
肿瘤血管生成与人类肿瘤的起始以及向更具侵袭性的行为进展有关。我们将讨论结直肠癌和胰腺腺癌起始和进展背后的遗传事件,特别关注血管生成的调节。一种分泌型成纤维细胞生长因子(FGF)结合蛋白(FGF-BP),它是FGFs的细胞外伴侣分子,已被证明可增强FGF介导的生化和生物学事件,并且是肿瘤依赖性血管生成的关键限速因子。对存档样本的组织化学和原位杂交研究表明,FGF-BP在结直肠癌和胰腺腺癌起始早期被诱导。我们将讨论这种分泌蛋白作为血清标志物用于识别高危人群的潜力。
