Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] . Biochemical events lead to characteristic cell changes (morphology) and death. [2] .

Sep 13, 2024 · Apoptosis is the normal, planned death of damaged cells in your body. It’s an important process that helps keep you healthy. But when it happens too often or not often enough, you can develop problems like cancer or Alzheimer’s disease. Researchers are exploring drugs that can manage apoptosis in your body to treat various conditions.

Jun 6, 2017 · Apoptosis is a process that occurs in multicellular when a cell intentionally “decides” to die. This often occurs for the greater good of the whole organism, such as when the cell’s DNA has become damaged and it may become cancerous.

The meaning of APOPTOSIS is a genetically directed process of cell self-destruction that is marked by the fragmentation of nuclear DNA, is activated either by the presence of a stimulus or removal of a suppressing agent or stimulus, is a normal physiological process eliminating DNA-damaged, superfluous, or unwanted cells, and when halted (as by ...

Mar 20, 2024 · Apoptosis is programmed cell death. It is an essential process in development, growth, repair, and immune function. However, excessive or insufficient apoptosis results in serious health conditions. Apoptosis serves several vital purposes: Development and Morphogenesis: It shapes tissues and organs during embryonic development.

Apr 30, 2024 · First identified in the 1970s, apoptosis was considered parallel to mitosis. Many years later, apoptosis is defined as the ATP-dependent, enzyme-mediated, genetically programmed death of cells that are either no longer required or pose a threat to the organism.

4 days ago · Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair. Apoptosis also plays a role in preventing cancer.

Apoptosis is vital in facilitating embryonic development and maintaining tissue homeostasis and immunological functioning. It is a complex interplay of intrinsic and extrinsic signaling pathways that ultimately converges on executing the apoptotic program.

Mar 8, 2025 · apoptosis, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged cells are then disposed of in an orderly fashion.

This process is therefore called programmed cell death, although it is more commonly called apoptosis (from a Greek word meaning “falling off,” as leaves from a tree). The amount of apoptosis that occurs in developing and adult animal tissues can be astonishing.
