核膜蛋白Lamins和Emerin的癌种特异性表达及调控机制研究进展OA
Advances in cancer-type-specific expression and regulation of nuclear envelope proteins Lamins and Emerin
核膜作为真核生物的细胞核关键功能结构,其核心组分核纤层蛋白(Lamins)及Emerin蛋白通过动态调控基因组稳定性、信号通路交互及核骨架-细胞骨架耦联,在肿瘤的发生、发展过程中发挥重要作用.本综述系统梳理核膜蛋白在肺癌、肝癌、结直肠癌、乳腺癌及前列腺癌中的研究进展,重点剖析其驱动肿瘤恶性表型的分子机制.最新研究进展主要体现在以下3个方面:①在基因组稳定性方面,最新研究证实核纤层结构缺陷是诱导核膜破裂与DNA损伤应答失调的直接原因;② 在表观重编程方面,研究阐明Lamin B1通过招募EZH2复合体催化H3K27me3修饰,进而沉默抑癌基因的分子通路;③ 在信号网络交互层面,最新研究发现,Notch-Wnt通路可通过HES1/TCF4复合体增强转录活性,而PI3K/Akt通路则通过抑制GSK3β磷酸化以促进β-catenin稳定化.深入解析核膜蛋白的动态调控机制,有望为肿瘤精准诊疗提供新策略.未来研究应整合多组学数据,系统阐明核膜蛋白调控网络的保守性和癌种特异性,并致力于开发Lamins异构体特异性抑制剂及靶向核膜-信号通路轴的联合治疗方案,从而提升靶向治疗的应答率并改善患者预后.
The nuclear envelope is a key functional structure of the eukaryotic cell nucleus.Its core components,Lamins and Emerin,play important roles in cancer by dynamically regulating genome stability,signaling pathway interactions,and nucleo-cytoskeletal coupling.This review systematically summarized recent advances in the study of nuclear envelope proteins in lung,liver,colorectal,breast and prostate cancer with a focus on elucidating the molecular mechanisms by which these proteins drive malignant phenotypes.Key recent findings are highlighted in three areas:① In genomic stability,lamin defects have been identified as a direct cause of nuclear envelope rupture and dysregulated DNA damage response;② In epigenetic reprogramming,Lamin B1 has been shown to recruit the EZH2 complex to catalyze H3K27me3 modification,leading to the silencing of tumor suppressor genes;③ In signaling network interactions,recent studies have revealed that the Notch-Wnt pathway enhances transcriptional activity via the HES1/TCF4 complex,while the PI3K/Akt pathway promotes β-catenin stabilization by inhibiting GSK3β phosphorylation.A deeper understanding of the dynamic regulatory mechanisms of nuclear envelope proteins may provide novel strategies for precision cancer therapy.Future research should integrate multi-omics data to systematically elucidate the conserved and cancer-type-specific aspects of nuclear envelope protein networks,and efforts should be directed toward developing Lamins isoform-specific inhibitors and combination therapies targeting the nuclear envelope-signaling axis,thereby improving the response rate to targeted therapy and patient survival outcomes.
