Here, the weighted gene co-expression network analysis (WGCNA) was used to identify the specific modules and hub genes that are related to neuropathic pain. The microarray dataset of a neuropathic rat model induced by tibial nerve transection (TNT), including dorsal root ganglion (DRG) tissues from TNT model (n=7) and sham (n=8) rats, was downloaded from the ArrayExpress database (E-MTAB-2260). The co-expression network modules were identified by the WGCNA package. The protein\u2013protein interaction (PPI) network was constructed, and the node with highest level of connectivity in the network were identified as the hub gene. A total of 1739 genes and seven modules were identified. The most significant module was the brown module, which contained 215 genes that were primarily associated with the biological process (BP) of the defense response and molecular function of calcium ion binding. Furthermore, C\u2013C motif chemokine ligand 2 (Ccl2), Fos and tissue inhibitor of metalloproteinase 1 (Timp1) which were identified as the hub genes in the PPI network and two subnetworks separately. The in vivo studies validated that mRNA and protein levels of Ccl2, Fos and Timp1 were up-regulated in DRG and spinal cord tissues after TNT. The present study offers novel insights into the molecular mechanisms of neuropathic pain in the context of peripheral nerve injury.<\/jats:p>","DOI":"10.1042\/bsr20191511","type":"journal-article","created":{"date-parts":[[2019,10,18]],"date-time":"2019-10-18T10:32:30Z","timestamp":1571394750000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Weighted gene co-expression network analysis reveals specific modules and hub genes related to neuropathic pain in dorsal root ganglions"],"prefix":"10.1042","volume":"39","author":[{"given":"Nan","family":"Cheng","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yue","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuo-Lin","family":"Qiu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing-Yi","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zi-Qing","family":"Hei","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4997-9339","authenticated-orcid":false,"given":"Xiang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, The Third Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2019,11,13]]},"reference":[{"key":"2021111619531559700_B1","doi-asserted-by":"publisher","first-page":"1630","DOI":"10.1212\/01.wnl.0000282763.29778.59","article-title":"Neuropathic pain: redefinition and a grading system for clinical and research purposes","volume":"70","author":"Treede","year":"2008","journal-title":"Neurology"},{"key":"2021111619531559700_B2","doi-asserted-by":"publisher","first-page":"825","DOI":"10.1097\/j.pain.0000000000001164","article-title":"Systematic review and meta-analysis of genetic risk factors for neuropathic pain","volume":"159","author":"Veluchamy","year":"2018","journal-title":"Pain"},{"key":"2021111619531559700_B3","doi-asserted-by":"publisher","first-page":"559","DOI":"10.1186\/1471-2105-9-559","article-title":"WGCNA: an R package for weighted correlation network analysis","volume":"9","author":"Langfelder","year":"2008","journal-title":"BMC Bioinformatics"},{"key":"2021111619531559700_B4","doi-asserted-by":"publisher","first-page":"124","DOI":"10.7150\/ijbs.22619","article-title":"Ten hub genes associated with progression and prognosis of pancreatic carcinoma identified by co-expression analysis","volume":"14","author":"Zhou","year":"2018","journal-title":"Int.
