Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to the regulation or control of genes previously linked to ageing
Description: Mutations in the LMNA gene result in Hutchinson-Gilford progeroid syndrome. Two mouse models, Lmna null (Lmna(-/-)) and progeroid Lmna delta9 have been created, displaying these two pathologies, with an accordingly shorten lifespan. In both cases, however, a deficiency in the Sun1 gene resulted in reduced tissue pathologies and enhanced longevity. Similarly, a reduction of SUN1 overaccumulation in LMNA mutant fibroblasts and in cells derived from progeroid patients corrected nuclear defects and cellular senescence [2197]. Further studies are warranted.
