Purpose.

The aim of this work has been to review the scientific literature regarding the role of regucalcin in bone loss.

Method.

A bibliographic search was performed in the PubMed database. A total of 31 articles were used. After analyzing its content and applying the inclusion and exclusion criteria, a total of 13 articles were included.

Results

The decrease in femoral calcium content observed in regucalcin transgenic mice decreased with increasing age, suggesting that bone loss is not restored with bone modeling. In the same way, it was found that the addition of regucalcin with 1 to 100 nM significantly stimulated the baseline activity of NF-kB (P <0.01). Likewise, there was a significant decrease in the DNA content in femoral metaphyseal tissues, with a greater decrease in females than in males, these values being: 3,3 mg / g became 2,6 mg / g (P <0.01). Osteoclastic bone resorption increased in male and female transgenic regucalcin mice with increasing age. Also, exogenous regucalcin reveals suppressive effects on osteoblastogenesis and mineralization in vitro and that it had no effects on cell proliferation and apoptosis in osteoblast cells in short-term cultures.

Conclusion.

Regucalcin plays a fundamental role in the maintenance of cell homeostasis and the function of the cellular response in relation to bone mass.
