大鼠肝癌发生过程中bFGF的表达及意义(2)
作者:佚名; 更新时间:2014-12-13
GF阳性肿瘤预后较差,可能与bFGF提高胶原酶活性和纤维蛋白溶酶原激活因子,使肿瘤细胞易于侵入周围组织有关[8]。从而推测肝癌细胞产生的bFGF可能有多方面的作用,它可提高肝癌细胞分泌的蛋白水解酶的活性,使肝癌细胞侵入周围组织,还可通过旁分泌方式刺激血管内皮细胞分裂增殖,使肝癌组织血管化加快并发生转移[8]。肝癌发生常伴有肝纤维化和肝硬化,这也提示bFGF在肝癌发生和发展中起一定的作用[9]。
   
    总之,关于bFGF在肝癌发生发展中的作用及机制还有待于进一步研究,以便为肝癌的临床诊断与治疗提供实验依据。
