研究表明,成纤维细胞生长因子8b(fibroblast growth factor 8b,FGF8b)在大部分前列腺癌患者中表达上调,并在前列腺癌的侵袭性进展中发挥关键作用。在此,我们研究了来自FGF8b的gN螺旋结构域的短肽对前列腺癌细胞转移行为的影响。结果表明,合成肽可能通过抑制MAPK和Akt信号通路的激活,降低转移相关蛋白的表达,逆转FGF8b对前列腺癌细胞增殖、迁移和侵袭的影响,从而抑制前列腺癌细胞的侵袭表型。总的来说,这些结果强调了FGF8b模拟肽在晚期前列腺癌中的治疗潜力。
Previous studies have demonstrated that fibroblast growth factor 8b (FGF8b) is up-regulated in a large proportion of prostate cancer patients, and plays a key role in the aggressive progress of prostate cancer. Herein, we investigated the effects of a short peptide derived from the gN helix domain of FGF8b on the metastatic behaviors of prostate cancer cells. The results demonstrated that the synthetic peptide might reverse the effects of FGF8b on cell proliferation, migration and invasion by suppressing the activation of MAPK and Akt signaling cascades, and reducing the expressions of the metastasis-related proteins, resulting in suppression of the aggressive phenotype of the prostate cancer cells. Collectively, these results underline the therapeutic potential of the FGF8b mimic peptide in advanced prostate cancer.
