Age and heat stress as determinants of telomere length in a long-lived fish, the Siberian sturgeon.
International audience Telomeres shorten at each cell division due to the “end-replication problem”, but also in response to oxidative stress. Consequently telomeres shorten with age in many endotherms, and this shortening is accelerated under stressful environmental conditions. Data in ectotherm ve...
