40年前,Folkman和他的同事提出血管生成是对抗肿瘤的一个重要靶点。其中,血管内皮生长因子及其受体(VEGF-VEGFR)系统被深度地研究,几种阻断其功能的药物和单克隆抗体都已成功进入各种实体瘤患者治疗的临床阶段。贝伐珠单抗,靶向VEGF的人源化中和抗体是FDA 2004年批准的第一个抑制肿瘤血管生产的抗癌药品。最初贝伐珠单抗显示出可延长晚期大肠癌患者的生存期(Hurwitz et al.,2004)。很快,它的抗癌应用又扩展到其他类型实体瘤的治疗,包括肺非小细胞癌(NSCLC),乳腺癌和转移性肾细胞癌。尽管它在临床前取得了巨大的成功,但是除了肾细胞癌患者(Jain et al., 2006),其治愈率仅在接受联合疗法(比如 化疗,放射疗法结合)的肿瘤患者中观察到。比如在中国,2019年《非小细胞肺癌抗血管生成药物治疗中国专家共识》中,推荐意见 1“驱动基因突变阴性、PS0分-1分的晚期NSCLC患者中,推荐贝伐珠单抗联合含铂双药方案作为一线治疗选择(Zhi,2019)”。但是,对于抗肿瘤血管生成治疗获益的患者,出现的药物耐药大大降低了其治疗的效果。了解“血管生成”在特定肿瘤的“语境”中分子,细胞,微环境以及组织层面发生,发展,转移的机制;设计新的靶向血管生成的药物以增强抗血管生成的功效,克服适应性,或者耐药性;寻找和利用“鲁棒”的疗效生物标记物,联合其他治疗药物(化疗,小分子靶向治疗以及免疫治疗)将肿瘤个体治疗效果最大化;无疑这些努力将会为我们克服肿瘤,提高中国人的生命质量做出巨大的贡献。
贾涛博士过去10年依次从“VEGF靶向药物抵抗”,“FGF2-VEGF信号串扰”,“FGF2靶向药物发现”以及“克服铂类药物抵抗”四个角度系统开展了“靶向(肿瘤)血管生成、DNA损伤药物耐药机制,新药发现以及药理机制”的研究。贾涛博士和合作者提出“设计假生长因子表面 (图a)”,“生长因子诱导转录后调控信号促血管生成(图b)”,“从胞外基质中寻找新的抗血管生成片段(图c)”以及“寻找区别于顺铂DNA攻击特点化合物(图d)”的四个策略,在靶向肿瘤血管生成治疗以及其和化疗联合治疗领域取得了较为丰富的研究成果,同时也积累了一系列有趣且重要的科学问题。这一系列原创的工作对于理解血管生成不同信号网络之间的交流;认识细胞外基质微环境中生长因子作用靶点的机制;寻找生长因子可变剪接确定治疗的“生物标记物”,进而选择“优势人群”,分类病人进行治疗;以及设计新颖的靶向血管生成新途径的药物,包括纳米药物和多肽,抑制肿瘤以及克服抗血管生成药物耐药,特别是加深了解靶向VEGF系统的功能,定义联合治疗方案有重要的基础和临床转化意义。
