Functional mechanisms and abnormalities of the nuclear lamina
The roles of nuclear envelope components in chromatin organization, phase separation and transcriptional and epigenetic regulation are summarized to guide a better understanding of pathological alterations in diseases and ageing.
Abstract
Alterations in nuclear shape are present in human diseases and ageing. A compromised nuclear lamina is molecularly interlinked to altered chromatin functions and genomic instability. Whether these alterations are a cause or a consequence of the pathological state are important questions in biology. Here, we summarize the roles of nuclear envelope components in chromatin organization, phase separation and transcriptional and epigenetic regulation. Examining these functions in healthy backgrounds will guide us towards a better understanding of pathological alterations.
