“…Increased levels of mRNA were found to be due to the ROS-dependent increased stability since exposure to free radical scavengers attenuated this increase (Esposito et al, 1997). Of interest is a possible link between elevated ROS-mediated p21 WAF1/cip1 expression and a reported role of ROS in senescence (Chen et al, 1995).…”

“…Variability or inductive changes in the expression of these enzymes can signi®cantly in¯uence cellular redox potential. Such changes have been shown to occur during di erentiation, aging and senescence (Chen et al, 1995). Exogenous agents which induce ROS formation include chemical and physical carcinogens and various cytokines.…”

“…These events include DNA damage (DiLeonardo et al, 1994;Chen et al, 1995;Robles and Adami, 1998), as well as perturbations to chromatin organization (Ogryzko et al, 1996;Jacobs et al, 1999;Itahana et al, 2003;Narita et al, 2003). They also include the expression of certain oncogenes (Serrano et al, 1997;Zhu et al, 1998;Dimri et al, 2000) that deliver supraphysiological mitogenic signals to cells, and the overexpression of certain tumor suppressor genes (Sugrue et al, 1997;McConnell et al, 1998;Dai and Enders, 2000;Dimri et al, 2000;Beausejour et al, 2003).…”

“…Cette constatation a été confirmée à plusieurs reprises [4][5][6][7]. De plus, il a été montré que le fait de cultiver des fibroblastes humains dans une atmosphère où les pourcentages d'O 2 sont inférieurs aux 20 % « conventionnels » retarde leur entrée en sénescence et augmente le nombre de doublements de population [5,[7][8][9]. Ces différences de croissance selon la richesse en O 2 du milieu pourraient être liées, entre autres, au stress oxydatif qu'entraîne l'hyperoxie « culturelle » [8,10].…”
