Summary
Aging causes bone loss and disease. This review details naturally aging and premature aging mouse models, examining their bone phenotypes and molecular mechanisms to understand age-related bone diseases.
Area of Science:
- Gerontology
- Skeletal Biology
- Biomedical Research
Background:
- Aging is a natural process leading to bone loss and related diseases, posing significant health risks.
- Studying human aging bone loss is challenging due to logistical and financial constraints.
- Mice are valuable models for aging research due to physiological similarities and practical advantages.
Purpose of the Study:
- To provide a comprehensive review of aging mouse models for skeletal research.
- To analyze the characteristics, limitations, and applicability of these models.
- To elucidate the molecular mechanisms underlying age-related bone diseases.
Main Methods:
- Review of naturally aging mice.
- Analysis of various premature aging mouse models (e.g., SAMP6, POLG mutant, LMNA, SIRT6, ZMPSTE24, TFAM, ERCC1, WERNER, KL/KL-deficient).
- Summary of molecular mechanisms including DNA damage, senescence, telomere shortening, oxidative stress, BMSC abnormalities, and mitochondrial dysfunction.
Main Results:
- Detailed characterization of bone phenotypes in different aging mouse models.
- Identification of key molecular pathways contributing to age-related bone loss.
- Comparison of naturally aging and prematurely aging models for research suitability.
Conclusions:
- Aging mouse models offer critical insights into the pathogenesis of age-related bone diseases.
- Understanding these models aids in developing therapeutic strategies.
- Further research using these models is essential for combating skeletal aging issues.

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

3.5K
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...
