Previous studies have shown that many children with some inflammation-related diseases often have short stature, but whether inflammation is the underlying mechanism of ISS has not been studied. Here, we attempt to explore the role of inflammation in the occurrence and development of ISS and to demonstrate an available clinical diagnostic model of ISS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Frozen serum samples were collected from ISS patients (n = 4) and control individuals (n = 4). Isobaric tags for relative and absolute quantitation (iTRAQ) combined with LC-MS\/MS analysis were applied to quantitative proteomics analysis. To assess clusters of potentially interacting proteins, functional enrichment (GO and KEGG) and protein-protein interaction network analyses were performed, and the crucial proteins were detected by Molecular Complex Detection (MCODE). Furthermore, serum levels of two selected proteins were measured by ELISA between ISS patients (n = 80) and controls (n = 80). In addition, experiments<jats:italic>in vitro<\/jats:italic>were used to further explore the effects of crucial proteins on endochondral ossification.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 437 proteins were quantified, and 84 DEPs (60 upregulated and 24 downregulated) were identified between patients with ISS and controls. Functional enrichment analysis showed that the DEPs were primarily enriched in blood microparticle, acute inflammatory response, protein activation cascade, collagen-containing extracellular matrix, platelet degranulation, etc. According to the results of top 10 fold change DEPs and MCODE analysis, C1QA and C1QB were selected to further experiment. The expression levels of C1QA and C1QB were validated in serum samples. Based on the logistic regression analysis and ROC curve analysis, we constructed a novel diagnostic model by serum levels of C1QA and C1QB with a specificity of 91.2% and a sensitivity of 75% (AUC = 0.900, p &amp;lt;0.001). Finally, the western blotting analysis confirmed the expression levels of OCN, OPN, RUNX2, and Collagen X were downregulated in chondrocytes, and the outcome of Collagen II was upregulated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study is the first to demonstrate the significant role of inflammation in the development of ISS. In addition, we identify C1QA and C1QB as novel serum biomarkers for the diagnosis of ISS.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2021.721812","type":"journal-article","created":{"date-parts":[[2021,9,17]],"date-time":"2021-09-17T06:10:00Z","timestamp":1631859000000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["A Novel Diagnostic Predictive Model for Idiopathic Short Stature in Children"],"prefix":"10.3389","volume":"12","author":[{"given":"Jinghong","family":"Yuan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi","family":"Du","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiwen","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanqin","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xigao","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xijuan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyu","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,9,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2008-0509","article-title":"Consensus Statement on the Diagnosis and Treatment of Children With Idiopathic Short Stature: A Summary of the Growth Hormone Research Society, the Lawson Wilkins Pediatric Endocrine Society, and the European Society for Paediatric Endocrinology Workshop","volume":"93","author":"Cohen","year":"2008","journal-title":"J Clin Endocrinol Metab"},{"key":"B2","doi-asserted-by":"publisher","first-page":"71","DOI":"10.1159\/000502901","article-title":"The Challenge of Defining and Investigating the Causes of Idiopathic Short Stature and Finding an Effective Therapy","volume":"92","author":"Inzaghi","year":"2019","journal-title":"Horm Res Paediatr"},{"key":"B3","doi-asserted-by":"publisher","first-page":"e205199","DOI":"10.1001\/jamapediatrics.2020.5199","article-title":"Association of Childhood Growth Hormone Treatment With Long-Term Cardiovascular Morbidity","volume":"175","author":"Tidblad","year":"2021","journal-title":"JAMA Pediatr"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2015.1982","article-title":"Inflammatory Bowel Disease in Children and Adolescents","volume":"169","author":"Rosen","year":"2015","journal-title":"JAMA Pediatr"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1016\/s0022-3476(98)70024-1","article-title":"Growth Status in Children With Cystic Fibrosis Based on the National Cystic Fibrosis Patient Registry Data: Evaluation of Various Criteria Used to Identify Malnutrition","volume":"132","author":"Lai","year":"1998","journal-title":"J Pediatr"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-014-3022-2","article-title":"Growth Abnormalities in Children and Adolescents With Juvenile Idiopathic Arthritis","volume":"34","author":"Bechtold","year":"2014","journal-title":"Rheumatol.
