Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description: NFKB1 is a component of the NF-kappa-B complex, involved in oxidative pathways and a myriad of other processes. Its role in ageing is unclear, even though NFKB1 appears to be related to age-related changes in inflammation and maybe in other age-related processes too [260]. In addition, age-relation changes in NF-kappa-B have been reported for numerous tissues [261]. In nfkb1-/- mice, both median and maximum lifespan are reduced (median is ~33% lower). The reduction in lifespan is also acompanied by multiple signs of premature ageing (hair loss or early greying, scruffy fur and cachexia, skin inflammation and delayed wound healing, thinning of the epidermis, lost neuromuscular coordination, premature body mass loss and loss of fat from inguinal, epididymal and mesenteric depots) [3544].
