Cellular senescence and the skeleton: pathophysiology and therapeutic implications
The Journal of Clinical Investigation
|February 1, 2022
Summary
Cellular senescence, a key aging process, drives bone loss and fragility. Targeting senescent cells with senolytics shows promise for treating age-related bone conditions and other diseases.
Area of Science:
- Gerontology and regenerative medicine
- Skeletal biology and aging research
Background:
- Cellular senescence is a fundamental aging mechanism implicated in tissue degeneration.
- Senescent cells accumulate in aging bone, contributing to bone loss and fragility.
- Senescence also mediates skeletal issues in conditions like diabetes, radiation, and chemotherapy.
Purpose of the Study:
- To explore cellular senescence as a therapeutic target for age-related bone conditions.
- To investigate the role of senescent cells in skeletal aging and fragility.
- To highlight the potential of senolytic drugs for treating multiple age-related diseases.
Main Methods:
- Review of existing evidence on cellular senescence in bone aging.
- Analysis of the role of senescent cells in age-related bone loss and fragility.
- Discussion of senolytic drug development targeting senescent cell survival mechanisms.
Main Results:
- Substantial evidence indicates senescent cell accumulation in the aging bone microenvironment.
- Targeting senescent cells has shown efficacy in preventing age-related bone loss in preclinical models.
- Cellular senescence is a significant factor in skeletal fragility linked to various conditions.
Conclusions:
- Senescent cells are a viable therapeutic target for ameliorating aging across multiple tissues, particularly the skeleton.
- Senolytics offer a promising strategy for simultaneously treating multiple age-related comorbidities.
- Further development of senolytic therapies could revolutionize the management of age-related bone diseases and systemic aging.

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...

01:29Bone Disorders
4.1K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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,...

01:40Bone Remodeling
38.7K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
