Outline of Final Research Achievements

Fibroblast-like synovial cells from RA patients (RA-FLS) can differentiate into osteoblast and miR-218 was down-regulated during osteogenic differentiation of RA-FLS. Induction of miR-218 in RA-FLS decreased ROBO1 expression. Conversely, the knockdown of miR-218 increased the expression of ROBO1. Finally, miR-218 promoted osteogenic differentiation of RA-FLS through DKK-1 suppression. Our results showed that miR-218 modulate osteogenic differentiation of RA-FLS through ROBO1/DKK-1 axis. This attractive hypothesis needs to be further tested in animal models.
