It seems to play a prominent role in development of the intervertebral disc (IVD) and in postnatal maintenance. There is little work on IHH in the IVD. Hence the aim of the current study was to investigate the role of Indian Hedgehog in the pathology of facet joint (FJ) OA. 24 patients diagnosed with lumbar intervertebral disk herniation or degenerative spinal stenosis were included. Preoperative magnetic resonance imaging (MRI) and Osteoarthritis Research Society International (OARSI) histopathology grading system was correlated to the mRNA levels of <jats:italic>GLI1<\/jats:italic>, <jats:italic>PTCH1<\/jats:italic> and <jats:italic>HHIP<\/jats:italic> in the FJs. The Weishaupt grading and OARSI scores showed high positive correlation (r\u2009=\u20090.894) (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01). MRI Weishaupt grades showed positive correlation with <jats:italic>GLI1<\/jats:italic> (r\u2009=\u20090.491), <jats:italic>PTCH1<\/jats:italic> (r\u2009=\u20090.444) and <jats:italic>HHIP<\/jats:italic> (r\u2009=\u20090.654) mRNA levels (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05 in each case). OARSI scores were also positively correlated with <jats:italic>GLI1<\/jats:italic> (r\u2009=\u20090. 646), <jats:italic>PTCH1<\/jats:italic> (r\u2009=\u20090. 518) and <jats:italic>HHIP<\/jats:italic> (r\u2009=\u20090.762) mRNA levels (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01 in each case). Cumulatively our findings indicate that Indian HH signaling is increased in OA and is perhaps a key component in OA pathogenesis and progression.<\/jats:p>","DOI":"10.1038\/srep10290","type":"journal-article","created":{"date-parts":[[2015,5,20]],"date-time":"2015-05-20T15:31:02Z","timestamp":1432135862000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Indian Hedgehog signaling pathway members are associated with magnetic resonance imaging manifestations and pathological scores in lumbar facet joint osteoarthritis"],"prefix":"10.1038","volume":"5","author":[{"given":"Feng","family":"Shuang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu-Xun","family":"Hou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia-Liang","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun-Li","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia-Guang","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2015,5,20]]},"reference":[{"key":"BFsrep10290_CR1","doi-asserted-by":"publisher","first-page":"216","DOI":"10.1038\/nrrheum.2012.199","volume":"9","author":"AC Gellhorn","year":"2013","unstructured":"Gellhorn, A.
