Background:
Osteoporosis and tumour-associated antigen (TAA) levels are associated with inflammatory processes, but little remains known about TAA levels and bone mineral density (BMD).
Aims:
We determined whether or not high-normal TAA levels are associated with a lower BMD in healthy women.
Methods:
A total of 3769 healthy women were enrolled from the health screening programme over 5 years. Each participant had undergone a basic health examination. Serum carbohydrate antigen (CA)-125, CA-19-9, carcinoembryonic antigen (CEA) and alpha-fetoprotein levels were evaluated as tumour markers. The correlations between serum TAA levels and BMD were analysed.
Results:
Carbohydrate antigen 125 and CEA levels were positively associated with a higher BMD in the pre-menopause. In the post-menopause, the CA-125 level was positively associated with BMD. In the pre-menopause, CA-125 (r = 0.102; P < 0.001) and CEA levels (r = 0.134; P < 0.001) had a significant correlation with BMD. In the post-menopause, CA-125 was negatively associated with alkaline phosphatase (r = -0.298; P < 0.001).
Conclusions:
There was a significant positive association between CA-125 and BMD in healthy women. Additional basic and clinical studies on the relationship between CA-125 and bone are needed.

01:29Bone Disorders
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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

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...
