Suppression of replicative senescence by rapamycin in rodent embryonic cells

Abstract excerpt

The TOR (target of rapamycin) pathway is involved in aging in diverse organisms from yeast to mammals. We have previously demonstrated in human and rodent cells that mTOR converts stress-induced cell cycle arrest to irreversible senescence (geroconversion), whereas rapamycin decelerates or suppresses geroconversion during cell cycle arrest. Here, we investigated whether rapamycin can suppress replicative...
