The Effect of Aging on Tissues

The 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...

Area of Science:

Ophthalmology
Gerontology
Molecular Biology

Background:

Physical activity benefits elderly well-being, but exercise's precise impact on aging lens pathology is unclear.
Aging leads to pathological changes in the lens, affecting vision.
Understanding these mechanisms is crucial for developing interventions.

Purpose of the Study:

To investigate the effects of swimming exercise on the aging mouse lens.
To identify molecular mechanisms underlying exercise-induced improvements in the aging lens.
To explore the role of specific genes, like Ciart, in lens aging and exercise response.

Main Methods:

Comparative study using young sedentary (YS), aging sedentary (AS), and aging exercising (AE) C57BL/6J mice.
Histopathological analysis (H&E staining) of lens morphology.
Transcriptomic analysis (RNA-seq, qPCR) and immunohistochemistry to assess gene expression and protein changes.

Main Results:

Swimming exercise alleviated histopathological aging changes in the lens.
Exercise downregulated key aging-associated pathways, including calcium signaling and cell adhesion.
10 out of 92 differentially expressed genes between young and aging lenses were mitigated by exercise, with Ciart showing significant responsiveness.

Conclusions:

Exercise offers benefits for the aging lens, potentially through modulating specific molecular pathways.
Ciart and its related pathways warrant further investigation for their role in lens aging.
Findings support exercise as a potential strategy to maintain lens health in aging individuals.
