Summary
Marine invertebrates, like bivalves and sea urchins, live exceptionally long lives without apparent aging. Studying their cellular and molecular mechanisms offers insights into aging and potential longevity research models.
Area of Science:
- Gerontology
- Marine Biology
- Molecular Biology
Background:
- Oceans host long-lived invertebrates (>100 years) with continuous growth and reproduction.
- These species exhibit no apparent age-related decline or increased mortality.
- Understanding their longevity offers alternative models for aging research.
Purpose of the Study:
- Review cellular and molecular aging aspects in marine invertebrates.
- Focus on bivalves and sea urchins as model organisms.
- Evaluate their potential for aging research and identify future research directions.
Main Methods:
- Literature review of existing data on aging in marine invertebrates.
- Analysis of cellular and molecular changes associated with aging.
- Comparative study focusing on bivalves and sea urchins.
Main Results:
- Many marine invertebrates exhibit negligible senescence.
- Limited data exists on molecular mechanisms of longevity in these species.
- Bivalves and sea urchins show promise as models for studying aging.
Conclusions:
- Marine invertebrates possess unique aging defense mechanisms.
- Further research is needed to elucidate molecular pathways of longevity.
- These species can advance our understanding of aging and healthspan.

01:19The Effect of Aging on Tissues
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...
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,...
