Abstract:

Long non-coding RNAs (lncRNAs) are a class of long non-coding RNAs about 200 bp in length that generally cannot be protein-encoded and have various biological functions. It is involved in the regulation of gene expression through transcriptional, translational and DNA epigenetic modifications. As a relatively nascent field, current research on lnc-RNA has focused on regulatory roles in the regulation of embryonic growth and stem cell differentiation as well as the development and progression of tumors. However, an increasing number of lncRNAs have been implicated as candidate regulators of inflammatory pathways associated with osteoarthritis pathology. In addition, more and more studies have found that lncRNAs are differentially expressed in osteoarthritic joint tissues. However, there are few reports on the correlation between lncRNAH19 and osteoarthritis (OA). Based on the latest research at home and abroad, this review focued on the regulatory mechanism of lncRNAH19 in osteoarthritis, including Notch signaling, wingless(Wnt)signaling, endogenous competitive RNAs (ceRNA), lnc-RNA/microRNA/messenger RNA(mRNA), etc. Determining the expression and functional roles of lncRNAs in osteoarthritis can not only advance the understanding of epigenetics underlying osteoarthritis pathology, but may ultimately help identify novel targets for therapeutic intervention.
