MicroRNAs (miRNAs) are small RNAs that fulfill diverse functions by negatively regulating gene expression. Here, we investigated the involvement of miRNAs in the chondrogenic differentiation of chick limb mesenchymal cells and found that the expression of miR-221 increased upon chondrogenic inhibition.

Growth Arrest-Specific 5 (GAS5) is known to negatively regulate cell survival and is aberrantly expressed in several cancers. The influence of GAS5 on osteoarthritis (OA) has not been determined. To address this, articular chondrocytes were isolated from relatively normal (Non-OA) and clear OA regions (OA) of cartilage in total knee replacement (TKR)(More)
Even though osteoarthritis (OA) is the most common musculoskeletal dysfunction, there are no effective pharmacological treatments to treat OA due to lack of understanding in OA pathology. To better understand the mechanism in OA pathogenesis and investigate its effective target, we analyzed miRNA profiles during OA pathogenesis and verify the role and its(More)
Despite growing importance of long non-coding RNAs (lncRNAs) in normal physiological and disease conditions, our knowledge of RA-related lncRNAs remains limited. Therefore, we aimed to identify lncRNA signatures that have prognostic values in RA. There was a notably high expression level of Hotair in blood mononuclear cells and serum exosome of rheumatoid(More)
Studies have shown the roles of miR-9 and its validated target, protogenin (PRTG) in the differentiation of chondroblasts to chondrocyte and in the pathogenesis of osteoarthritis (OA). We hypothesized that miR-9 plays a distinct role in endochondral ossification and OA pathogenesis and the present study was undertaken to identify this role. In the studies,(More)
MicroRNAs (miRNAs) have been implicated in various cellular processes, such as cell fate determination, cell death, and tumorigenesis. In the present study, we investigated the role of miRNA-34a (miR-34a) in the reorganization of the actin cytoskeleton, which is essential for chondrocyte differentiation. miRNA arrays to identify genes that appeared to be(More)
MicroRNAs function as an endogenous mode of fine gene regulation and have been implicated in multiple differentiation and developmental processes. In the present study, we investigated the role of miRNA-34 during chondrogenic differentiation of chick limb mesenchymal cells. We found that the expression of miR-34a increased upon chondrogenic inhibition.(More)
Non-coding RNAs have been less studied in cartilage development and destruction regulated by sophisticated molecular events despite their considerable theranostic potential. In this study, we identified significant down-regulation of mR-101 and up-regulation of lncRNA, HOTTIP in the processes of endochondral ossification and osteoarthritic progression. In(More)
Sulfuretin (3',4',6'-trihydroxyaurone), one of the key flavonoids isolated from Rhus verniciflua, is known to suppress inflammation and oxidative stress. However, the anti-cancer properties of sulfuretin as well as its mechanism of action remain poorly understood. Here, we show that the expression of miR-30C is markedly enhanced in sulfuretin-stimulated(More)
Recent increasing evidences showing the interconnection between mitochondria and peroxisome in performing metabolic functions imply that peroxisome dysfunction could lead to a wide variety of human diseases including cancer and osteoarthritis (OA) as mitochondria dysfunction. Even though there is a higher incidence and development of OA in diabetes mellitus(More)
