MicroRNA-19a promotes cell viability and migration of chondrocytes via up-regulating SOX9 through NF-κB pathway

miR-19a was down-regulated in synovium form OA patients. miR-19a could promote cell viability and migration of chondrocyte via positively regulating SOX9 expression through NF-κB signaling pathway. This study might provide the novel strategy for clinical treatment of OA caused by chondrocyte function degradation.
