Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a mammalian model organism
Description: NFKBIA inhibits NF-kappa-B by forming a complex with it, and may be involved in inflammation, apoptosis, differentiation, and growth. Downregulation of NFKBIA with age appears to occur in the rat liver [871]. Transgenic mice expressing dominant-negative IkB, and exhibiting functional inhibition of NF-kB signaling in endothelial cells, were protected from age-related insulin resistance and vascular senescence and, displayed a prolonged lifespan. In addition, the mice had also decreased oxidative stress markers, increased muscle blood flow, enhanced active-phase locomotor activity, and aortic upregulation of mitochondrial sirtuin-related proteins [2115]. Whether NFKBIA plays a role in human ageing remains to be determined.
