apoptotic 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. (apoptosis) a type of cell death in which the cell uses specialized cellular machinery to kill itself; a cell suicide mechanism that enables metazoans to control cell number and eliminate cells that threaten the animal's survival
  2. Apoptosis (or) is the process of programmed cell death (PCD) that may occur in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. ...
  3. (Apoptosis) a form of cell death involving shrinking of the cell and eventual disposal of the internal elements of the cell by the body's immune system. Apoptosis is an active, non-toxic form of cell suicide that does not induce an inflammatory response. ...
  4. (apoptosis) Process of cell death that results from turning on specific, active processes in the cell that lead the cell to kill itself. This happens normally in some tissues, for example, during embryonic development when some groups of cells are removed from the animal. ...
  5. (apoptosis) Programmed cell death, that is, the death of cells by a specific sequence of events triggered in the course of normal development (e.g. cells between digits in the limb bud) or as a means of preserving normal function (e.g. in response to viral infection).
  6. (Apoptosis) The deliberate, programmed death of a cell.Apoptosis occurs as a normal part of life and helps the body stayhealthy. If cells are damaged (for example, cancerous cells or cellsinfected with HIV), the body orders those cells to die in order tocontain the disease.
  7. (apop·to·sis) programmed cell death; a genetically-determined process of cell self-destruction that is marked by the fragmentation of nuclear DNA; is activated either by the presence of a stimulus or by the removal of a stimulus or suppressing agent; is a normal physiological process eliminating ...
  8. (Apoptosis) Cell death due to a programmed pattern of gene expression; a form of cell death in which certain enzymes activate to degrade DNA within the nucleus, resulting in cellular degeneration and loss.
  9. (apoptosis) programed cell death as signalled by the nuclei in normally functioning human and animal cells when age or state of cell health and condition dictates. Cancerous cells, however, are unable to experience the normal cell transduction or apoptosis-driven natural cell death process.
  10. (apoptosis) cell death that occurs naturally as part of normal development, maintenance, and renewal of tissues within an organism.
  11. (apoptosis) (ap-o-TOE-sis): A normal series of events in a cell that leads to its death.
  12. (apoptosis) [app´ opp toe´ sis]   Normal cell death. Healthy cells live and die in a predictable pattern, and that keeps the number of cells in our bodies balanced. One new area of cancer therapy is directed at increasing the apoptosis of malignant cells to speed their destruction.
  13. (Apoptosis) Cell death; Fragmentation of a cell into membrane-bound particles that are then eliminated by phagocytosis.
  14. (Apoptosis) The self-destruction of a cell, also called "cell suicide."
  15. Apoptosis is the process a cell in the body goes through when it dies. Apoptosis is a scheduled process, controlled by the body.
  16. (Apoptosis) Also known as programmed cell death or cell suicide, it is the natural process by which cells die in order to prevent the spread of disease. In diseases such as cancer, this cell death mechanism does not function properly and cancer cells are allowed to proliferate. ...
  17. (apoptosis) programmed cell death. Apoptosis is the body's mechanism for eliminating undesirable or excessive immune system activity, e.g., immune cells that attack the body's own tissues. Abnormal apoptosis is often Seen in HIV disease.
  18. (Apoptosis) a form of programmed cell death where cells are eliminated without releasing potential harmful compounds into their surroundings. Apoptosis differs from necrosis, a form of cell death often accompanied by the release of toxins into the environment and subsequent inflammation
  19. (Apoptosis) [a-pop-toe-sis] Programmed self-destruction of cells.
  20. (APOPTOSIS) Developmental or "programmed" cell death characterized by membrane blobs, extensive chromatin condensation, and DNA fragmentation. Plays a role in negative selection of developing T cells and the killing of targets by cytotoxic T lymphocytes.
  21. (APOPTOSIS) "Cell suicide". Thought to be primarily a way that the body clears out immune cells that respond to the body's own proteins, apoptosis involves a complete physical destruction of a cell, driven by enzymes. ...
  22. (APOPTOSIS) The process of programmed cell death. This process can be caused by external factors, for example it may be triggered by immune cells, or may be activated due to cellular processes such as a damaged genome. ...
  23. (Apoptosis) (ap-up-TOE-sis or a-po-TOE-sis) programmed cell death or "cell suicide." This is a normal, controlled sequence of events in which damaged cells self-destruct to protect the body. Cancer cells are resistant to this process, which makes them harder to kill. ...
  24. (Apoptosis) A form of cell death in which cells shrink and disappear. It is sometimes referred to as "cell suicide" and was first described more than 40 years ago. Some scientists think that in PD, the substantia nigra nerve cells die by apoptosis.
  25. (Apoptosis) A process whereby a cell causes its own breakdown (death).
