The cell death, occurring during embryonic development, T and B cell maturation and endocrine-induced atrophy, is a physiological apoptosis which controls the amount of cells in the body. Apoptosis can also be induced by various factors, such as ionizing radiation and anti-tumour agents which damage DNA, and has been proposed to be a consequence of the induced expression of some tumour-related genes or increase of the proteins sta-
