After intersection with GSE63514, we found the obvious tendency in different histological grades. Then we screened the top 24 genes, and confirmed the top 8 genes in human cervix tissues. Immunohistochemical (IHC) results confirmed that keratin 17 (KRT17) was not expressed in normal cervical tissues and was over\u2010expressed in cervical cancer. Cysteine\u2010rich secretory protein\u20102 (CRISP2) was less expressed in high\u2010grade squamous intraepithelial lesions (HSILs) than in other histological grades.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>For the good repeatability and consistency of KRT17 and CRISP2, they may be good candidate biomarkers. Combined analysis of KRT17, CRISP2 expression at both genetic and protein levels can determine different histological grades of cervical squamous cell carcinoma. Such combined analysis is capable of improving diagnostic accuracy of cervical cancer.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cam4.3799","type":"journal-article","created":{"date-parts":[[2021,2,24]],"date-time":"2021-02-24T05:57:59Z","timestamp":1614146279000},"page":"2063-2074","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Discovery
