Current diagnostic methods for PE typically identify the condition after 20 weeks of gestation, often when the disease has already manifested and reached an advanced stage. The situation underscores the urgent need for early biomarkers capable of effective screening and diagnosis. Our review addresses this challenge by utilizing bioinformatics approaches as an alternative method prior to preclinical and clinical studies. Specifically, we focus on FRAGmentomics-based Methylation Analysis (FRAGMA), targeting the CGCGCGG sequence motif for methylation studies in cell-free DNA (cfDNA). Since cfDNA is largely derived from the placenta, the FRAGMA approach is particularly promising, given that the primary pathophysiology of PE originates in the placenta, and methylation patterns are unique to specific tissues. In the previous research, we identified 66 genes containing this sequence motif that are implicated in the pathophysiology of PE, and only six genes – FN1, ITGA2, ITGA5, ITGB1, ITGB3, and VWF – show potential as early detection biomarkers for PE. These genes still require further investigation to confirm their utility as biomarkers for PE in the future studies.</div></div>","PeriodicalId":10205,"journal":{"name":"Clinica Chimica Acta","volume":"574 ","pages":"Article 120339"},"PeriodicalIF":3.2,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A thorough investigation of these interference mechanisms is necessary to improve assay methodologies, ensuring greater reliability and precision. In recent years, significant advancements in mass spectrometry (MS) technology have sparked increased interest in its application for cTn testing. For instance, liquid chromatography-tandem mass spectrometry (LC-MS/MS) employs multiple reaction monitoring (MRM) to accurately quantify cardiac troponin I (cTnI)-specific tryptic peptides along with their fragment ions. This technique effectively reduces immunoassay interference while improving analytical specificity. Compared to traditional immunoassays, MS-based approaches alleviate matrix effects and analytical interferences while achieving superior specificity. Nonetheless, clinical adoption remains constrained by technical complexity; thus clinicians can obtain more reliable diagnostic insights. This review summarizes the current landscape of cTn detection technologies by examining the prevalence of false-positive results across various methods. It further explores both the practical applications and challenges associated with MS-based techniques in cTn testing.
