Summary
Human life span may not have a natural limit. Targeting aging
Area of Science:
- Gerontology
- Genetics
- Mortality Studies
Background:
- Human life expectancy has risen, but maximum lifespan has plateaued around 115 years.
- This suggests a potential natural limit to human longevity.
Purpose of the Study:
- To investigate if human lifespan has a natural limit.
- To determine if interventions targeting aging can extend maximum lifespan.
Main Methods:
- Systematic analysis of 20th-century all-cause human mortality data.
- Examination of hundreds of aging interventions across multiple model organisms (yeast, worms, flies, rodents).
Main Results:
- After accounting for cause of death, median age of death and maximum lifespan increased proportionally.
- Aging interventions significantly extended median, maximum, and last survivor lifespans to a similar extent in model organisms.
Conclusions:
- The observed ceiling in human lifespan may be breakable.
- Targeting biological and genetic causes of aging offers a pathway to extend maximal human lifespan.

Replicative Cell Senescence
4.5K
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...

Aging
874
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
20.8K
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,...

The Effect of Aging on Tissues
3.8K
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...

Whole Body Regeneration
4.2K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Requirements for Human Life
14.3K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
