摘要
癌症是世界范围内的主要死亡原因。 Janus 激酶 (JAK) 信号转导和转录激活子 (STAT) 信号通路被异常激活,从而促进癌变。几种细胞因子是重要的癌症驱动因素。这些蛋白质与受体结合并使用 Janus 激酶 (JAK) 和 STAT 通路来传达它们的反应。癌症风险与 JAK-STAT 系统中的遗传差异有关。在涉及实体瘤细胞系模型的临床前研究中,JAK 抑制剂已被证明可减少 STAT 起始、组织增殖和细胞存在。 JAK 抑制剂,尤其是鲁索替尼、JAK1 或 2 阻滞剂,使细胞系和小鼠模型更容易受到放射疗法、生物反应调节剂疗法和溶瘤病毒治疗的影响。许多 JAK 拮抗剂已经或现在正在癌症患者中作为单一疗法或在临床研究中与其他药物联合进行评估。在临床前研究中,某些 JAK 抑制剂显示出有希望的抗癌作用;然而,明确评估其针对 JAK/STAT 系统在实体瘤中的有效性的临床试验尚未完成。 JAK 抑制是一种针对实体瘤中 JAK/STAT 系统的有前景的策略,值得在临床研究中进一步测试。本文总结了 STATs 的上游加速器 Janus 激酶 (JAKs) 作为一种在各种恶性情况下降低 STAT 活性的技术的作用,这将有助于科学家在未来产生更具体的药物分子。
