title: [Cellular and molecular mechanisms of aging: a review].
abstract: Since the beginning of this century, a large body of experimental data and observations accumulated concerning experimental and clinical gerontology. These data can be classified and analyzed according to the level of experimentation or observation as concerning aging at the molecular, cellular level or at higher levels of hierarchical organisation such as tissues, organs or the whole organism. Observations of these higher levels are mostly derived from epidemiological studies of human aging, horizontal studies or preferably vertical studies. The relative coherence of data collected at the molecular and cellular levels renders plausible a tentative of interpretation of aging phenomena at higher levels or hierarchical organisations from the tissues to the whole organism by using the data obtained at the molecular and cellular levels. The present article is a tentative for this kind or integrative interpretation of aging.
