Dictionary » A » Apoptosis



(Science: cell biology) Programmed cell death as signalled by the nuclei in normally functioning human and animal cells when age or state of cell health and condition dictates.

An active process requiring metabolic activity by the dying cell, often characterised by cleavage of the dna into fragments that give a so called laddering pattern on gels.

cells that die by apoptosis do not usually elicit the inflammatory responses that are associated with necrosis, though the reasons are not clear.

cancerous cells, however, are unable to experience the normal cell transduction or apoptosis-driven natural cell death process.

Cancer = Mutation: Stopping Mutation Would Cure Cancer?

... agents have various ways of action, but they all aim to impair mitosis and thus kill fast dividing cells as well -- or force them to undergo apoptosis. So, as peculiar as it may sound, in radiotherapy cancer is fought with its own weapons: mutations.

My “Eureka” moment. A cure for cancer.

... not so much because the cancer cells divide abnormally but because the cancer cells don't die or undergo programmed cell death called "apoptosis" normally and are abnormally immortal. Such normally dividing but abnormally immortal cells would cease dividing if an all-body-tissue ...

... to the strand. but it gets shorter as the replication cycle. as cells age, the telomeres get shorter! shortest telomere or lack of it, signals apoptosis. Cancer cells avoids apoptosis, by synthesis of more and more telomeres which synthesis the ends of chromosomes for the cancer cells...

... for many cancers (as will be discussed later) targets p53 (tumor supressor pathway) which results in the preservation of the virus by preventing apoptosis of its host cell (DNA-damage-response). Mechanistically, DDR-signaling in mammals are caried out by ATM and ATR which reduces cyclin-dependent ...

Apoptosis in the substantia nigra

... been described in neurons of the aged human brain. However, the cell death process associated with neuronal senescence remains to be elucidated. Apoptosis and autophagic degeneration, two modes of programmed cell death described in embryogenesis and tissue renewal in adult, have been observed ...
