Effects of Senescence
Senescence can cause a number of effects, including:
- Loss of Cell Proliferation:Senescent cells cease to divide that limits the body’s ability to replace damaged or dying cells.
- Altered Cellular Function: Senescent cells undergo changes in gene expression and functionality that impact their normal roles or can disrupt tissue and organ functions.
- Inflammation: Senescent cells can release pro-inflammatory molecules as part of the senescence-associated secretory phenotype (SASP) that contributes to chronic inflammation and promote age-related diseases.
- Tissue Dysfunction: Accumulation of senescent cells in tissues can contribute to impaired tissue function that affects organs and systems throughout the body.
- Contribution to Aging: The presence of senescent cells is associated with the aging process, and their accumulation over time is linked to age-related diseases and degenerative conditions.
- Cancer Prevention: While senescence can limit the proliferation of damaged cells and prevent the development of cancer.
- Impact on Surrounding Cells: The SASP released by senescent cells can influence neighboring cells, either promoting inflammation or affecting the behavior of nearby healthy cells.
What is Senescence? – Senescent Cells And Senescence In Plants
Senescence is the process by which cells stop dividing and enter a state of permanent growth arrest without undergoing cell death. Senescence cells get old and weaken, causing a decline in tissue function and decay. Senescence in plants is a programmed death of leaves as part of developmental cycles. In animals, senescent cells contribute to aging and age-related diseases.
Senescence can be induced by unrepaired DNA damage or other cellular stresses. It plays a role in normal development, maintains tissue homeostasis, and limits tumor progression. In this article, we will read about what is senescence, its causes, and effects, senescent cells, the different types of senescence in plants, theories of aging, factors affecting senescence, and its importance.
