Currently, the sensitivity and specificity of diagnostic markers for GC are low, so it is urgent to find new biomarkers with higher sensitivity and specificity. tRNA-derived small RNAs are a kind of small non-coding RNAs derived from tRNAs. It is abundant in cancer cells and body fluids. Our goal is to find the differentially expressed tRNA-derived small RNAs in GC to explore their potential as a GC biomarker.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Quantitative real-time PCR was used to detect the expression level of hsa_tsr016141. The molecular characteristics of hsa_tsr016141 were verified by agarose gel electrophoresis, Sanger sequencing, Actinomycin D Assay, and Nuclear and Cytoplasmic RNA Separation Assay. The diagnostic efficiency of hsa_tsr016141 was analyzed through receiver operating characteristic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The expression level of hsa_tsr016141 in GC tissues and serum was significantly increased. The serum expression level showed a gradient change between GC patients, gastritis patients, and healthy donors and was positively correlated with the degree of lymph node metastasis and tumor grade. ROC analysis showed that the serum expression level of hsa_tsr016141 could significantly distinguish GC patients from healthy donors or gastritis patients. Besides, the expression level of hsa_tsr016141 in GC patients decreased significantly after the operation (P&amp;lt;0.0001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Serum hsa_tsr016141 has good stability and specificity and can be used for dynamic monitoring of GC patients, suggesting that serum hsa_tsr016141 can be a novel biomarker for GC diagnosis and postoperative monitoring.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fonc.2021.679366","type":"journal-article","created":{"date-parts":[[2021,5,13]],"date-time":"2021-05-13T07:12:14Z","timestamp":1620889934000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":35,"title":["Serum hsa_tsr016141 as a Kind of tRNA-Derived Fragments Is a Novel Biomarker in Gastric Cancer"],"prefix":"10.3389","volume":"11","author":[{"given":"Xinliang","family":"Gu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuo","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Liang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoqing","family":"Ju","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,5,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2019.07.045","article-title":"Burden of Gastric Cancer","volume":"18","author":"Thrift","year":"2020","journal-title":"Clin gastroenterology hepatology Off Clin Pract J Am Gastroenterological Assoc"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.Epi-13-1057","article-title":"Gastric Cancer: Descriptive Epidemiology, Risk Factors, Screening, and Prevention","volume":"23","author":"Karimi","year":"2014","journal-title":"Cancer epidemiology Biomarkers Prev Publ Am Assoc Cancer Research cosponsored by Am Soc Prev Oncol"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.31937","article-title":"Estimating the Global Cancer Incidence and Mortality in 2018: GLOBOCAN Sources and Methods","volume":"144","author":"Ferlay","year":"2019","journal-title":"Int J Cancer"},{"key":"B4","doi-asserted-by":"publisher","first-page":"119","DOI":"10.1186\/s12943-020-01231-4","article-title":"Circrnas: Biogenesis, Functions, and Role in Drug-Resistant Tumours","volume":"19","author":"Ma","year":"2020","journal-title":"Mol Cancer"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1177\/0004563216649377","article-title":"Micorna-425-5p is a Potential Prognostic Biomarker for Cervical Cancer","volume":"54","author":"Sun","year":"2017","journal-title":"Ann Clin Biochem"},{"key":"B6","doi-asserted-by":"publisher","first-page":"00065\u20134","DOI":"10.1007\/s10620-020-06819-w","article-title":"HIF1A-AS2 Promotes the Proliferation and Metastasis of Gastric Cancer Cells Through Mir-429\/PD-L1 Axis","author":"Mu","year":"2021","journal-title":"Digestive Dis Sci"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymthe.2021.01.031","article-title":"Circehbp1 Promotes Lymphangiogenesis and Lymphatic Metastasis of Bladder Cancer Via Mir-130a-3p\/Tgf\u03b2r1\/VEGF-D Signaling","author":"Zhu","year":"2021","journal-title":"Mol Ther J Am Soc Gene Ther"},{"key":"B8","article-title":"High Turnover Rate of Transfer RNA in Tumor Tissue","volume":"37","author":"Borek","year":"1977","journal-title":"Cancer Res"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197912)44:6<2120::aid-cncr2820440623>3.0.co;2-6","article-title":"Trna Breakdown Products as Markers for Cancer","volume":"44","author":"Speer","year":"1979","journal-title":"Cancer"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(93)90529-y","article-title":"The C.
