Advances in understanding the mechanisms of repairing damaged nuclear envelop

Abstract

The nuclear envelope (NE) separates genomic DNA from the cytoplasm in eukaryotes. The structure of the NE is dynamically altered not only in mitotic disassembly and reassembly but also during interphase. Recent studies have shown that the NE is frequently damaged by various cellular stresses that degenerate NE components and/or disrupt their functional interactions. These stresses are referred to as 'NE stress'. Accumulating evidence has demonstrated that NE stress potentially causes severe cellular dysfunctions, such as cell death and genome instability. In this review, the concept of NE stress, the processes repairing damage of the NE caused by NE stress, and the molecular mechanisms by which NE stress contributes to disease pathogenesis are introduced.
