Summary
Aging is organismal decline, while cellular senescence is cell-cycle arrest. This review clarifies their distinct roles and overlaps, focusing on senescent cell accumulation
Area of Science:
- Gerontology
- Cell Biology
- Biomedical Research
Background:
- Aging and cellular senescence are often confused, leading to research ambiguities.
- Aging is organismal decline; senescence is stress-induced cell-cycle arrest.
- Understanding their distinct yet interconnected nature is crucial for aging research.
Purpose of the Study:
- To clarify the distinct molecular underpinnings of aging and cellular senescence.
- To highlight the mechanistic overlaps and roles in health and disease.
- To emphasize the contribution of senescent cells to age-related functional decline.
Main Methods:
- Literature review of molecular mechanisms.
- Analysis of conceptual overlaps and differences.
- Discussion of emerging biomarkers and therapeutic strategies.
Main Results:
- Aging and cellular senescence are biologically distinct but interconnected processes.
- Accumulation of senescent cells actively contributes to age-related functional decline.
- Senescence is triggered by various cellular stresses.
Conclusions:
- Distinguishing aging from cellular senescence is vital for accurate research.
- Targeting senescent cells offers potential therapeutic interventions for age-related disorders.
- Emerging strategies include senolytics and partial reprogramming.

02:15Replicative Cell Senescence
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:37Mitochondria
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
02:41Telomeres and Telomerase
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded DNA.
