Research summary

Nuclear envelope transmembrane (NET) protein regulation of tissue specific genome organisation in differentiation and disease

Mutations in widely expressed nuclear envelope (NE) proteins cause many distinct diseases with tissue-specific pathologies including muscular dystrophies, lipodystrophies, neuropathy, dermopathy, and premature-aging syndromes. This raised the question: how could mutations in the same ubiquitous protein cause distinct diseases affecting different tissues? Hypothesizing that tissue-specific partners mediate the tissue-specific pathologies, we identified candidate partners with proteomics. The NE connects on the inside to chromatin and genome organisation is disrupted in patient cells. If our hypothesis is correct, it follows that these tissue-specific NETs might direct tissue-specific patterns of genome organisation with consequences for gene expression and we have found this to be the case.

We found three muscle-specific NETs that re-position genes to the NE that are needed early in myogenesis, but subsequently become inhibitory and must be tightly shut down. Their combined knockdown blocks myogenesis. Thus, NE gene recruitment enables tighter regulatory control. Importantly, we found mutations in these muscle NETs in unlinked Emery-Dreifuss muscular dystrophy patients, further arguing the importance of this novel regulatory mechanism. We have found similar effects with a fat-specific NET in adipogenesis and found that mice lacking this protein have difficulty producing fat, become insensitive to insulin, have metabolic dysfunction and a general lipodystrophy phenotype.

It appears that NE connections can also influence gene activities in the nuclear interior as during lymphocyte activation we found that released genes that were flanked by unchanging NE-associated regions remained within <0.8 µm from the NE, presumably because the flanking contacts restrict their diffusion and thus promote their association in chromosome compartments in what we call the “constrained diffusion” hypothesis. We showed that several genes and an enhancer up to 14 Mb away from one another are all released upon lymphocyte activation and associate in A2 sub-compartments. This type of regulation could contribute temporal control to lymphocyte activation.

Other lines of investigation include: 1) Studying the structure of intermediate filament lamins with the Rappsilber lab. 2) Investigating NET effects on nuclear size changes in several cancer types and screening for small molecules targeting this with the Auer and Tyers labs. Nuclear size changes mark increased disease severity and this is also tissue- specific. 3) Investigating STING (NET23) function at the NE, finding NE-specific partners that contribute to innate immune responses 4) Investigating how herpesviruses escape through the NE, finding that vesicle fusion proteins in the NE are needed for efficient virus nuclear egress.

DORA statement: This review covers much of what is known about spatial genome organization in embryonic stem cells and early development and how it can go awry in human disease. As is typically the case for review articles from my lab, we also performed a bioinformatics analysis to add some new data, this time on the evolutionary conservation of architectural proteins involved in 3D spatial genome organization.
