肝细胞癌 (HCC) 细胞通过复杂的机制发展出多药性耐药性 (MDR),阻碍化疗. 本综述探讨了克服肝癌中MDR治疗的最新进展和策略,以改善治疗结果.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 初级肝癌,特别是肝细胞癌 (HCC),由于高死亡率和发病率的增加,对全球健康构成了重大挑战.
- 化疗是高级HCC的基石治疗,但其疗效经常受到内在或获得的耐药性影响.
- 在HCC中,多药耐药性 (MDR) 是一个主要的临床障碍,由癌细胞固有的异质性驱动.
研究的目的:
- 审查最近关于肝细胞癌 (HCC) 耐药性背后的分子机制的研究进展.
- 总结目前和新兴的干预策略,旨在克服肝癌中多药耐药性 (MDR).
- 提供有关提高HCC化疗疗效果的潜在治疗途径的见解.
主要方法:
- 对HCC中药物耐药性的最新研究进行了全面的文献综述.
- 分析导致化疗耐药性的分子机制,包括输送器过度表达,适应性细胞反应,DNA损伤修复,表观遗传学和瘤微环境.
- 识别和综合针对这些抵抗机制的各种干预策略.
主要成果:
- 在HCC中,耐药性涉及多方面的机制,包括排泄,亡逃避,自,内分泌网膜应激,DNA损伤修复缺陷,表观遗传变化和瘤微环境 (TME).
- 药物外流载体的过度表达和适应性细胞反应是MDR的关键贡献者.
- 功能障碍的DNA损伤修复 (DDR),表观遗传修改和TME/细胞外基质 (ECM) 也在对抗治疗中起着至关重要的作用.
结论:
- 了解HCC中MDR的复杂分子基础对于开发有效的治疗策略至关重要.
- 针对特定的阻力机制,如流量输送器或TME组件,为克服MDR提供了有希望的途径.
- 本次审查强调了需要创新的方法来改善晚期肝癌患者的临床结果,这些患者面临化疗耐药性.
