摘要

Abstract

Endochondral bone formation is an important route for bone repair. Although emerging evidence has revealed the functions of long non-coding RNAs (lncRNAs) in bone and cartilage development

the effect of lncRNAs in endochondral bone repair is still largely unknown. Here

we identified a lncRNA

named Hypertrophic Chondrocyte Angiogenesis-related lncRNA (HCAR)

and proved it to promote the endochondral bone repair by upregulating the expression of matrix metallopeptidase 13 (Mmp13) and vascular endothelial growth factor α (Vegfa) in hypertrophic chondrocytes. Lnc-HCAR knockdown in hypertrophic chondrocytes restrained the cartilage matrix remodeling and decrease the CD31

Emcn

vessels number in a bone repair model. Mechanistically

we proved that lnc-HCAR was mainly enriched in the cytoplasm using fluorescence in situ hybridization (FISH) assay

and it acted as a molecular sponge for miR-15b-5p. Further

in hypertrophic chondrocytes

lnc-HCAR competitively bound to miR-15b-5p to increase Vegfa and Mmp13 expression. Our results proved that lncRNA is deeply involved in endochondral bone repair

which will provide a new theoretical basis for future strategies for promoting fracture healing.
