Abstract:
To summarize promising areas of investigation in osteoporosis and to stimulate further research in this area, as discussed in a recent international conference. Over the recent years, there has been an improvement in the knowledge of molecular pathways involved in bone formation and resorption with the development of new drugs to treat osteoporosis. Intact parathyroid hormone, teriparatide, and anti-sclerostin monoclonal antibody are anabolic drugs, whereas denosumab and odanacatib are anti-resorptive drugs with more reversible effects as compared to bisphosphonates. Anabolic and anti-resorptive agents have different effects on bone, and research in this area includes the efficacy of combination and sequential therapies with them. New insights in the molecular pathways of bone remodeling have clarified the mechanisms responsible for skeletal fragility in several forms of secondary osteoporosis, such as that occurring in type 2 diabetes, following drug exposure and systemic inflammatory diseases. Future research is needed to address the efficacy of anti-osteoporotic drugs in these more recently recognized conditions of skeletal fragility. Osteoporosis continues to be an important field of biomedical research.
Insights
New osteoporosis drugs target bone formation and resorption pathways. Research is exploring combination therapies and efficacy in secondary osteoporosis, including diabetes and inflammatory diseases.

- Endocrinology
Background:
- Significant advancements in understanding bone formation and resorption molecular pathways.
- Development of novel therapeutic agents for osteoporosis treatment.
Purpose of the Study:
- To review current research frontiers in osteoporosis.
- To identify promising areas for future investigation.
- To stimulate further research in osteoporosis and related skeletal fragility.
Main Methods:
- Review of recent international conference discussions.
- Analysis of emerging molecular pathways in bone remodeling.
- Evaluation of existing and novel osteoporosis drug classes.
Main Results:
- Identification of anabolic agents (intact parathyroid hormone, teriparatide, anti-sclerostin monoclonal antibody) and anti-resorptive agents (denosumab, odanacatib).

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...

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...
