Apoptosis

Introduction: Apoptosis

Description of Apoptosis

Apoptosis: Cell's internal "suicide" mechanism causing death of the cell.

Apoptosis: An active process of selective destruction of differentiated cells in multicellular organisms, apoptosis is one of two mechanisms by which cell death occurs (the other being necrosis, a pathological process). Important in ontogenesis, tumorigenesis, tissue turnover, lymphocyte selection and function, hormone-induced atrophy, etc., it serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth. Apoptosis is responsible for physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, including chromatin cleavage at regularly spaced sites and endonucleolytic cleavage of genomic DNA (DNA fragmentation) at internucleosomal sites.

Apoptosis: One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
