Bypassing Border Control: Nuclear Envelope Rupture in Disease

Border Disease Control Checkpoints: Are They Sufficient for Disease Control? The Present Situation in Thailand

Nuclear envelope rupture drives genome instability in cancer

The nuclear envelope, composed of two lipid bilayers and numerous accessory proteins, has evolved to house the genetic material of all eukaryotic cells. In so doing, the nuclear envelope provides a physical barrier between chromosomes and the cytoplasm. Once believed to be highly stable, recent studies demonstrate that the nuclear envelope is prone to rupture. These rupture events expose chromo...

Nuclear envelope, nuclear lamina, and inherited disease.

The nuclear envelope is composed of the nuclear membranes, nuclear lamina, and nuclear pore complexes. In recent years, mutations in nuclear-envelope proteins have been shown to cause a surprisingly wide array of inherited diseases. While the mutant proteins are generally expressed in most or all differentiated somatic cells, many mutations cause fairly tissue-specific disorders. Perhaps the mo...

Nuclear envelope rupture is induced by actin-based nucleus confinement

Repeated rounds of nuclear envelope (NE) rupture and repair have been observed in laminopathy and cancer cells and result in intermittent loss of nucleus compartmentalization. Currently, the causes of NE rupture are unclear. Here, we show that NE rupture in cancer cells relies on the assembly of contractile actin bundles that interact with the nucleus via the linker of nucleoskeleton and cytosk...

Nuclear envelope disease and chromatin organization.

The fifth U.K. meeting on nuclear envelope disease and chromatin brought together international experts from across the field of nuclear envelope biology to discuss the advancements in a class of tissue-specific degenerative diseases called the laminopathies. Clinically, these range from relatively mild fat-wasting disorders to the severe premature aging condition known as Hutchinson-Gilford pr...
