层粘连蛋白是普遍存在的核中间纤维,其突变可导致多种疾病,包括肌营养不良和扩张性心肌病。层粘连蛋白提供核稳定性,帮助细胞核连接到细胞骨架,并可以调节染色质组织和基因表达。尽管如此,层粘连蛋白的各种功能仍然不完全清楚。在这里,我们将重点讨论层粘连蛋白在核力学中的作用及其在人类疾病中的意义。最近的研究结果表明,核纤层蛋白突变可以降低核稳定性,增加核脆弱性,并干扰机械转导信号,这可能解释了许多核纤层蛋白病的肌肉特异性缺陷。与此同时,在许多癌症中已经报道了层粘连蛋白表达的改变,其结果是核变形能力的增加可以增强细胞通过紧密间质间隙的能力,促进转移。
Mutations in lamins, which are ubiquitous nuclear intermediate filaments, lead to a variety of disorders, including muscular dystrophy and dilated cardiomyopathy. Lamins provide nuclear stability, help connect the nucleus to the cytoskeleton, and can modulate chromatin organization and gene expression. Nonetheless, the diverse functions of lamins remain incompletely understood. Here, we focus on the role of lamins on nuclear mechanics and its implication in human diseases. Recent findings suggest that lamin mutations can decrease nuclear stability, increase nuclear fragility, and disturb mechanotransduction signaling, possibly explaining the muscle-specific defects in many laminopathies. At the same time, altered lamin expression has been reported in many cancers, where the resulting increased nuclear deformability could enhance the ability of cells to transit tight interstitial spaces, promoting metastasis.
