Osteopontin (OPN) shows promise as an early diagnostic biomarker for osteoporosis. Elevated serum OPN levels may indicate reduced bone mineral density (BMD) in postmenopausal women, aiding early osteoporosis detection.
Area of Science:
- Biochemistry
- Orthopedics
- Endocrinology
Background:
- Osteopontin (OPN) is implicated in bone metabolism.
- Its role as an early diagnostic marker for bone disorders requires clarification.
- Bone mineral density (BMD) is a key indicator for osteoporosis development.
Purpose of the Study:
- To systematically review the literature on the relationship between osteopontin and bone mineral density.
- To evaluate osteopontin as a potential early diagnostic biomarker for osteoporosis.
Main Methods:
- Systematic literature search of clinical trials.
- PubMed database search (1999-2020).
- Analysis of 7 eligible studies focusing on human subjects.
Main Results:
- Identified 7 clinical trials examining osteopontin and BMD.
- Found a potential association between serum OPN levels and BMD.
- Highlighted the need to reconcile conflicting literature findings.
Conclusions:
- Serum osteopontin (OPN) may serve as a valuable biomarker for early osteoporosis diagnosis.
- This is particularly relevant for postmenopausal women, irrespective of vertebral fractures.
- Further research is warranted to confirm OPN's role in osteoporosis management.

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...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

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...

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...
