ABSTRACT
BACKGROUND:
Glucocorticoids play an essential role in osteoblast differentiation, but excessive glucocorticoids will inhibit the osteoblastic phenotype. Regulation of 11β-hydroxysteroid dehydrogenase (11β-HSD) contributes to optimizing the effect of glucocorticoids.OBJECTIVE:
To summarize the effect of 11β-HSD in bone metabolism.METHODS:
The corresponding author retrieved PubMed and CJFD databases for the articles published before 2016 using the keywords "11β-HSD, bone" in English and Chinese, respectively. Totally 115 articles were retrieved, including 98 English and 17 Chinese articles, and finally 45 eligible articles were included in accordance with the inclusion criteria.RESULTS ANDCONCLUSION:
Glucocorticoid action can be regulated at prereceptor level by 11β-HSD. 11β-HSD1 activity may predict individual susceptibility to glucocorticoids, which instructs the individualized application of glucocorticoids precisely. 11β-HSD1 activity is closely related to osteoblast differentiation and the presence of an intrinsic differentiation-driven molecular switch inhibits the activity of 11β-HSD1. Instead of regulating the mesenchymal progenitors directly, gucocorticoids regulate the mesenchymal progenitors to differentiate into cranial skeleton mainly through mature osteoblasts. Short-term glucocorticoid exposure directly increases 11β-HSD1 activity and continuous exposure to glucocorticiod indirectly inhibits 11β-HSD1 activity.
