Summary
Calcidiol (25OH vitamin D(3)) deficiency is linked to aging diseases and cancer. Maintaining optimal calcidiol levels may help prevent age-related chronic diseases and cancers.
Area of Science:
- Endocrinology
- Oncology
- Gerontology
Background:
- Vitamin D deficiency, specifically of calcidiol (25OH vitamin D(3)), is implicated in aging-related chronic diseases, including cancer.
- The roles of calcidiol and calcitriol in homeostasis appear distinct, with calcidiol linked to differentiation and calcitriol to calcium regulation.
Purpose of the Study:
- To investigate the association between calcidiol levels and aging-related chronic diseases, particularly cancer.
- To differentiate the homeostatic roles of calcidiol and calcitriol in the context of aging and disease.
Main Methods:
- The study analyzed the relationship between serum calcidiol concentrations and the risk of aging-related diseases.
- Literature review and data analysis were employed to assess vitamin D bioactivity in aging phenomena.
Main Results:
- Calcidiol deficiency, insufficient solar exposure, and high calcidiol concentrations are associated with increased cancer risk.
- Aging phenomena exhibit a U-shaped association with vitamin D bioactivity, suggesting an optimal range.
- Imbalances in calcidiol, rather than calcitriol, appear to be a significant risk factor for cancer and chronic diseases.
Conclusions:
- Optimal serum calcidiol concentration is crucial for preventing age-related chronic diseases and cancers.
- Calcidiol plays a key role in differentiation homeostasis, making its imbalance a risk factor.
- Further research is needed to determine the precise optimal concentration of serum calcidiol for health maintenance.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

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...
01:29Bone Disorders
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...
