ING1a expression increases during replicative senescence and induces a senescent phenotype.

abstract：:Most human tissues express low levels of telomerase and undergo telomere shortening and eventual senescence; the resulting limitation on tissue renewal can lead to a wide range of age-dependent pathophysiologies. Increasing evidence indicates that the decline in cell division capacity in cells that lack telomerase can...
