Summary
Organisms age due to senescent cells, often caused by telomere shortening and damage. This study highlights how telomere dysfunction broadly contributes to human diseases associated with ageing.
Area of Science:
- Gerontology and cellular biology
- Molecular mechanisms of ageing
- Pathophysiology of age-related diseases
Background:
- Senescent cells accumulate with age and contribute to organismal dysfunction.
- Telomere shortening and damage are known drivers of cellular senescence.
- Accelerated telomere dysfunction is linked to several human ageing conditions.
Purpose of the Study:
- To consolidate evidence on the role of telomere dysfunction in ageing.
- To present a unified view of telomere dysfunction's contribution to human pathologies.
- To explore the link between telomere biology and age-related diseases.
Main Methods:
- Systematic review and evidence synthesis.
- Analysis of existing literature on telomere biology and ageing.
- Correlating telomere dysfunction with specific human pathologies.
Main Results:
- Telomere dysfunction is a significant factor in cellular senescence.
- Evidence supports a broad role for telomere dysfunction in multiple human diseases.
- Specific conditions associated with ageing are precipitated by accelerated telomere dysfunction.
Conclusions:
- Telomere dysfunction is a key mechanism underlying ageing and age-related diseases.
- Recognizing telomere dysfunction's contribution offers new perspectives on geriatric medicine.
- Further research into telomere maintenance may yield therapeutic strategies for ageing.

3.8K
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...

01:29Replication in Eukaryotes
15.0K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

01:19The Effect of Aging on Tissues
2.8K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

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...

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,...
