Abstract

Osteoarthritis (OA), or degenerative arthritis, is characterized by mechanical stress-induced changes in cartilage and bone. OA is a leading cause of chronic disability in North America and Europe. A recent study written by Blom and colleagues (Arthritis and Rheumatism 2009; 60:501-12) showed that elevated wnt signaling was observed in experimental OA as well as in patient samples. The authors found that the known wnt target WISP-1 (CCN4) was also overexpressed; CCN4 was sufficient to recapitulate an OA phenotype in vitro and in vivo, suggesting that CCN4 may be a novel target for drug intervention in OA. This commentary summarizes these exciting findings.

摘要

骨关节炎(OA),又称退行性关节炎,其特征为软骨和骨的机械性应激诱导改变。OA 是北美和欧洲慢性失能的主要原因。Blom 及其同事最近发表的一项研究(关节炎与风湿病 2009;60:501-12)显示,实验性 OA 以及患者样本中均观察到升高的 wnt 信号。作者发现,已知的 wnt 靶标 WISP-1(CCN4)也过表达;CCN4 足以在体外和体内重现 OA 表型,表明 CCN4 可能是 OA 药物干预的新靶点。这篇评论总结了这些令人兴奋的发现。
