GenAge entry for RGN (Homo sapiens)

Gene name (HAGRID: 145)

HGNC symbol: RGN
Aliases: SMP30; RC
Common name: regucalcin

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on indirect or inconclusive evidence linking the gene product to ageing in humans or in one or more model systems
Description: RGN is mostly expressed in the liver, yet its functions remain obscure [723]. Its expression levels decline with age, and RGN has been linked to age-related changes in calcium signalling in the liver of rats [724]. RGN-null mice show susceptibility to TNF- and FAS-mediated apoptosis [182] and increased oxidative stress in brain [1634]. SMP30/SOD1-double knockout mice exhibit abnormal plasma lipid metabolism, hepatic lipid accumulation and premature death resulting from impaired VLDL secretion, both compared to wild type, SMP30-knockout and SOD1-knockout mice [3618]. A role for RGN in human ageing remains to be determined.
