Apoptosis - Wikipedia
网页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 and death. [2]

网页2024年3月20日 · Apoptosis is a highly regulated and controlled process that unfolds in distinct stages, each characterized by specific cellular changes and biochemical events. Initiation: Internal or external signals trigger the apoptosis pathways. Early Apoptosis: Key indicators include cell shrinkage, chromatin condensation, and membrane blebbing.

网页2017年6月6日 · 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.
Apoptosis - StatPearls - NCBI Bookshelf
网页2024年4月30日 · This topic highlights the physiological process of apoptosis from the cellular to the systemic level, with clinical correlations to pathological conditions, incorporating current evidence-based literature. The mechanisms of apoptosis are differentiated from necroptosis, pyroptosis, and ferroptosis.
Programmed Cell Death (Apoptosis) - Molecular Biology of the …
网页In multicellular organisms, cells that are no longer needed or are a threat to the organism are destroyed by a tightly regulated cell suicide process known as programmed cell death, or apoptosis. Apoptosis is mediated by proteolytic enzymes called caspases, which trigger cell death by cleaving specific proteins in the cytoplasm and nucleus.
Apoptosis: Controlled demolition at the cellular level
网页Apoptosis, or programmed cell death, begins when enzymes called caspases start a controlled demolition process within the cell. This review covers the sequence of known steps involved in...
