Abstract

Resistance to cell death is one of the core hallmarks of cancer, with regulatory abnormalities particularly pronounced in the malignant progression and therapeutic resistance of melanoma. This review aims to systematically summarize the roles and mechanisms of regulated cell death (RCD) in melanoma. Currently, distinct types of RCD, including apoptosis, autophagy, pyroptosis, immunogenic cell death, necroptosis, and ferroptosis, have all been found to be involved in melanoma. Autophagy promotes the survival of melanoma cells under stress conditions through metabolic adaptation, yet its excessive activation can trigger cell death. Immunogenic cell death has the capacity to elicit adaptive immune responses in immunocompetent syngeneic hosts. Necroptosis, governed by the receptor-interacting protein kinase 1 (RIPK1)/RIPK3 mixed lineage kinase domain-like protein (MLKL) signaling axis, can synergize with immunotherapy to enhance anti-melanoma immune responses when activated. Pyroptosis, mediated by Gasdermin proteins, induces the release of inflammatory factors that reshape the tumor microenvironment and enhance the efficacy of immune checkpoint inhibitors. Ferroptosis, characterized by lipid peroxidation, can overcome melanoma resistance by targeting the solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) axis. Therapeutic strategies targeting RCD pathways have demonstrated breakthrough potential. Several agents have been developed to target RCD in order to suppress melanoma.

摘要

对细胞死亡的抵抗是癌症的核心特征之一,在黑色素瘤的恶性进展和治疗抵抗中,调节异常尤为明显。本综述旨在系统总结调节性细胞死亡(RCD)在黑色素瘤中的作用和机制。目前,已发现包括凋亡、自噬、焦亡、免疫原性细胞死亡、坏死性凋亡和铁死亡在内的不同类型的RCD均与黑色素瘤有关。自噬通过代谢适应促进应激条件下黑色素瘤细胞的存活,但其过度激活可引发细胞死亡。免疫原性细胞死亡能够在免疫健全的同基因宿主中引发适应性免疫反应。由受体相互作用蛋白激酶1(RIPK1)/RIPK3混合谱系激酶结构域样蛋白(MLKL)信号轴调控的坏死性凋亡在激活时可与免疫疗法协同作用,增强抗黑色素瘤免疫反应。由Gasdermin蛋白介导的焦亡可诱导炎症因子释放,重塑肿瘤微环境并增强免疫检查点抑制剂的疗效。以脂质过氧化为特征的铁死亡可通过靶向溶质载体家族7成员11(SLC7A11)/谷胱甘肽过氧化物酶4(GPX4)轴克服黑色素瘤耐药性。针对RCD途径的治疗策略已显示出突破潜力。已经开发了几种靶向RCD的药物来抑制黑色素瘤。
