"The finite proliferative potential of normal human cells leads to replicative cellular senescence, which is a critical barrier to tumour progression in vivo(1-3). We show that the human p53 isoforms Delta 133p53 and p53 beta(4) function in an endogenous regulatory mechanism for p53-mediated replicative senescence," scientists in the United States report.

"Induced p53 beta and diminished Delta 133p53 were associated with replicative senescence, but not oncogene-induced senescence, in normal human fibroblasts. The replicatively senescent fibroblasts also expressed increased levels of miR-34a, a p53-induced microRNA(5-9), the antisense inhibition of which delayed the...
