Definition of senescence in English:

senescence

noun sɪˈnɛs(ə)nssəˈnɛsəns

mass nounBiology

1The condition or process of deterioration with age.
衰老
Example sentencesExamples
- Although it is characterized as being a deterioration process, senescence is considered to be a highly evolved genetic process.
- But most healthy mammalian cells managed just a few dozen divisions before they stopped, a process known as replicative senescence.
- The degradation of proteins and the remobilization of amino acids to developing tissues is a prominent process during senescence.
- A pretreatment of cold-induction temperatures had little effect on the course of tissue senescence under these conditions.
- Oxidative processes during senescence involve an increase in enzyme activities generating oxygen radicals and superoxide ions.
Synonyms
elderliness, old age, oldness, seniority, maturity, dotage, senility
1. 1.1 Loss of a cell's power of division and growth.
  细胞分裂和生长能力的丧失，老化
  Example sentencesExamples
  Additional carbon would also be released into the rhizosphere with border cell senescence and death.
  The terms senescence and programmed cell death have led to some confusion.
  Behind this zone of environmental invasion is a wave of cell senescence, death and necrotrophic disappearance.
  Mortality barriers to human cell immortalization and effectors of replicative cellular senescence in human cells
  We have devised a functional approach to clone genes involved in the regulation of cell growth and senescence.
  Synonyms
  feebleness, enfeeblement, infirmity, weakness, frailty, debilitation, debility, sickliness, incapacitation, malaise

Derivatives

senescent

adjective sɪˈnɛs(ə)ntsəˈnɛs(ə)nt

Biology

For leaf and stem samples, mature but not senescent tissues were taken.
Example sentencesExamples
- A feature shared by senescent cells in culture and in vivo is shortening of the telomeres.
- It is known that induction of telomere shortening leads to the extinction of yeast clones similar to a senescent phenotype.
- Fourth, after some 30 passages, cells cultured at 33°C stopped proliferating, suggesting a senescent state.
- The molecular mechanisms for vacuolar protein degradation and the nutrient recycling pathway in senescent leaves are generally not clear.
