This study aimed to explore the mechanisms of early\u2010onset type 2 diabetes mellitus (T2DM) by analyzing proteomic changes at different stages of glucose metabolism.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 40 individuals undergoing routine physical health examinations between December 2016 and April 2017 were enrolled. Subjects were divided into four groups based on fasting blood glucose (FPG) levels: FPG\u2009&lt;\u20095.6\u00a0mmol\/L (group A); FPG\u2009\u2265\u20095.6\u00a0mmol\/L and &lt;6.1\u00a0mmol\/L (group B); FPG\u2009\u2265\u20096.1\u00a0mmol\/L and &lt;7.0\u00a0mmol\/L (group C); and FPG\u2009\u2265\u20097.0\u00a0mmol\/L (group D). Each group had 10 cases. Sera from these 40 subjects were analyzed by label\u2010free quantitative liquid chromatography coupled with tandem mass spectrometry (LC\/MS\/MS). LC\/MS\/MS with selected reaction monitoring mode was also performed for qualitative and quantitative metabolomics analysis. Differentially expressed proteins were identified. Partial least squares discriminant analysis (PLS\u2010DA) and orthogonal partial least squares discriminant analysis (OPLS\u2010DA) were used to analyze the differentially expressed metabolites.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 202 differentially expressed proteins were screened and were identified as mainly secreted proteins. Comparing group A with group B, 32 proteins were up\u2010regulated and 18 proteins were down\u2010regulated. Comparing group A with group C, 24 proteins were up\u2010regulated and 24 proteins were down\u2010regulated. Comparing group A with group D, 19 proteins were up\u2010regulated and 17 proteins were down\u2010regulated. The fold change for up\u2010regulated proteins was &gt;1.2,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05, while the fold change for down\u2010regulated proteins was &lt;\u22121.2,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05. PLS\u2010DA and OPLS\u2010DA revealed 113 differentially expressed metabolites. Correlation analysis of differentially expressed metabolites of group A versus group B revealed that among the down\u2010regulated differential proteins, transforming growth factor \u03b2\u2010induced protein ig\u2010h3 correlated negatively with metabolite L\u2010saccharin, while among the up\u2010regulated differential proteins, apolipoprotein C\u2010IV correlated negatively with metabolite 3\u2010methyloxindole. Among all differentially expressed proteins, 19 proteins were associated with early initiation of chronic inflammation, including CD14 and CSF\u20101R, which were newly identified in the early onset of T2DM.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Many proteins are differentially expressed between prediabetes and after T2DM diagnosis, although the specific mechanism remains unclear. The expression level of CD14 was significantly up\u2010regulated and that of CSF\u20101R was significantly down\u2010regulated when FPG was \u22655.6\u00a0mmol\/L, suggesting that CD14 and CSF\u20101R may be important markers for early\u2010onset T2DM and may serve as new targets for T2DM treatment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/rcm.9448","type":"journal-article","created":{"date-parts":[[2022,12,2]],"date-time":"2022-12-02T19:31:35Z","timestamp":1670009495000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Analysis of protein expression changes in patients with prediabetes using proteomics approaches"],"prefix":"10.1002","volume":"37","author":[{"given":"Huan","family":"Li","sequence":"first","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2109-0063","authenticated-orcid":false,"given":"Xiaomin","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huili","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Qiang","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan Ting","family":"He","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guirong","family":"Bai","sequence":"additional","affiliation":[{"name":"Department of Endocrinology First People's Hospital of Yinchuan  Yinchuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12,27]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"IDF.IDF Diabetes Atlas 9th edition 2019.
