Both qPCR and Western blotting were utilized to investigate the levels of PTPRK in placentas of 20 PE and 20 normal pregnancies.</p><p><strong>Results: </strong>The allele frequency of <i>PTPRK</i> rs3190930 differed significantly between PE and controls and was particularly significant in severe PE subgroup and early-onset PE subgroup. PTPRK is primarily localized in placental trophoblast cells. The mRNA and protein levels of PTPRK in PE were significantly higher than those in controls.</p><p><strong>Conclusion: </strong>These results suggest that PTPRK appears to be a previously unrecognized susceptibility gene for PE in Han Chinese women, and its expression is also associated with PE, while <i>ROS1</i> rs9489124 has no apparent correlation with PE risk.</p>","PeriodicalId":14132,"journal":{"name":"International Journal of Hypertension","volume":"2021 ","pages":"3275081"},"PeriodicalIF":1.9,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8505056/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39515696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
