背景技术
蛋白酪氨酸激酶(Tyrosine Protein Kinase,TPK)是细胞信号传递过程中的重要因子,参与一系列细胞功能,与细胞生长、分化、增殖密切相关,它催化ATP的γ磷酸基转移到许多重要蛋白质的酪氨酸残基上,使酚羟基磷酸化,从而传递信号。酪氨酸激酶属于蛋白激酶家族,按其结构可以分为两大类:受体酪氨酸蛋白激酶(Receptor PTKs)和非受体酪氨酸蛋白激酶(Non-receptor PTKs),这两类酪氨酸蛋白激酶按结构同源性可进一步分为多个酶属。人体共有518种激酶基因,其中90种PTKs已被发现,包括受体型的酪氨酸激酶58种和非受体型的酪氨酸激酶32种。受体型的酪氨酸激酶包括血小板生长因子受体(platelet-derived growth factorreceptor,PDGFR)、表皮生长因子受体(epidermal growth factorreceptor,EGFR)、成纤维细胞生长因子受体(fibroblast growth factor receptor,FGFR)等成员,它们通常具有一个细胞外结构域、一个跨膜区以及一个细胞内激酶域。癌症临床研究表明,这些受体及其配体与很多肿瘤都有重要联系,很多癌症出现了相关生长因子的过量表达,导致过量的酪氨酸磷酸化信号传入细胞。非受体型的酪氨酸激酶(nrPTKs)一般没有细胞外结构,它们通常与细胞膜耦联或存在于胞质中,包括Abl激酶、Src激酶、C-端Src激酶等成员。在肿瘤组织中nrPTKs常被激活,再激活下游的信号传导途径,促进细胞增殖、抵抗细胞凋亡,促使肿瘤发生和发展。TPK分成受体依赖型酪氨酸蛋白激酶(RTK)和非受体依赖型酪氨酸蛋白激酶。受体依赖型即催化性受体,是通过跨膜结构的酶蛋白受体连接细胞内外,与生长因子配体结合后激活信号传导。受体型的酪氨酸蛋白激酶包括EGFR、PDGFR和M-CSF以及FGFR、VEGFR和HGFR等。RTK都含有活性的细胞内结构域。肿瘤的发生跟受体与相应配体的结合有着密切关系,大多恶性肿瘤都出现了生长因子的过量表达,导致异常的酪氨酸磷酸化信号传入到细胞中。肿瘤细胞中受体激活后通过与下游分子结合并激活,使其具有酪氨酸激酶活性,促进细胞增殖。
血管生成是由血管形成新萌芽的过程或从预先存在的血管分裂出来的过程。在正常生理条件下,血管生成是促血管生成因子和抑血管生成因子协调作用的复杂过程。当血管生成发生异常就会引起一系列的疾病,包括视网膜病、关节炎、子宫内膜异位症、动脉粥样硬化和癌症。Folkman在70年代初就已经证实原发性肿瘤的生长、转移必须依赖新血管的生成。事实上,肿瘤为了生长需要新的毛细血管来提供营养并带走代谢废物,新血管也为在后期的肿瘤细胞转移中提供帮助。
血管生成取决于多种生长因子,其中VEGF在肿瘤血管生成时对内皮细胞表现出的专一性、重要性而使其成为研究热点。VEGF是刺激血管生成的众多因子中最强有力的生长因子,又称血管通透因子,它直接作用于内皮细胞,促使有丝分裂发生、新生血管生长。VEGF家族成员有A、B、C、D、E和胎盘生长因子。多数恶性肿瘤细胞有自分泌VEGF功能,转移的肿瘤细胞释放VEGF刺激了局部血管生成。
作为VEGF的特异受体VEGFR在肿瘤新生血管中高表达。血管内皮细胞具有遗传稳定性,所以VEGFR抑制剂不易产生耐药性,易于到达靶点,在肿瘤组织内高浓度聚集。VEGFR主要有3类:VEGFR-1(FLT-1);VEGFR-2(KDR)和VEGFR-3(FLT-4)。VEGFR是具有高度特异性的跨膜受体,蛋白结构由胞外区、跨膜区和胞内区3部分组成。胞外区是其与VEGF的结合位点,含有7个免疫球蛋白样的功能区;胞内区有1个插入片段的酪氨酸蛋白激酶(PTK);VEGFR的生物学功能是与其配体结合后通过级联式的磷酸化反应使信号逐级传导和放大,引起细胞相应的生物学效应,从而诱导血管内皮细胞的分裂、增殖和迁移,增强毛细血管通透性、使血浆外渗,促成周围血管大量形成。
研究证明VEGF/VEGFR通路与肿瘤血管生成和淋巴管形成密切相关。该信号通路为自身的生存发展创造了有利的微环境,它可促进其微血管的生成,获取丰富的营养供应,淋巴管的生成在肿瘤扩散过程中发挥着更重要的作用,因此阻断VEGF/VEGFR信号通路可以有效抑制肿瘤血管生成和淋巴管生成,抑制肿瘤的生长和转移。
