Patients taking glucocorticoid or glucocorticoid-like drugs for an extended period of time may develop osteoporosis, termed glucocorticoid-induced osteoporosis (GIOP). GIOP is the most common form of secondary osteoporosis, but the mechanism underlying its development is unclear. In the present study, we used prednisolone to treat zebrafish larvae to investigate GIOP. Our RNA deep-sequencing (RNA-seq) results show that prednisolone affects genes known to act in the extracellular region. Therefore the extracellular region, extracellular matrix, and collagen trimer might be involved in glucocorticoid-induced osteoporosis. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that the focal adhesion signaling pathway is the most enriched signaling pathway in terms of differentially expressed genes (DEGs). In this pathway, integrin subunit alpha 10 (itga10) and integrin subunit beta like 1 (itgbl1), genes encoding two adapter proteins, were down-regulated in the prednisolone-treated larvae. Further experiments showed that prednisolone contributes to GIOP by down-regulating itga10 and itgbl1.
