InterLINCing Chromatin Organization and Mechanobiology in Laminopathies

AbstractPurpose of reviewIn this review, we explore the chromatin-related consequences of laminopathy-linked mutations through the lens of mechanotransduction.Recent findingsMultiple studies have highlighted the role of the nuclear lamina in maintaining the integrity of the nucleus. The lamina also has a critical role in 3D genome organization. Mutations in lamina proteins associated with various laminopathies result in the loss of organization of DNA at the nuclear periphery. However, it remains unclear if or how these two aspects of lamin function are connected. Recent data suggests that unlinking the cytoskeleton from the nuclear lamina may be beneficial to slow progress of deleterious phenotypes observed in laminopathies.SummaryIn this review, we highlight emerging data that suggest interlinked chromatin- and mechanical biology-related pathways are interconnected in the pathogenesis of laminopathies.
