The complexity of CVDs arises from their multifactorial etiology, including genetic, environmental, and lifestyle factors. Early diagnosis and effective treatment remain critical for reducing mortality and improving patient outcomes, yet conventional methods often fall short in providing precise, timely information for disease management. MicroRNAs are small non-coding RNAs that regulate gene expression and play pivotal roles in various biological processes, including cardiovascular health. Among them, miR-21 has garnered significant attention due to its involvement in cardiac remodeling, fibrosis, inflammation, and hypertrophy. Elevated levels of miR-21 are frequently observed in conditions such as myocardial infarction, heart failure, and coronary artery disease, positioning it as a potential biomarker for early detection and disease progression. Furthermore, therapeutic strategies targeting miR-21, such as antagomirs and innovative delivery systems, have shown promise in preclinical studies, though challenges like off-target effects and delivery inefficiencies persist. This review aims to provide a comprehensive understanding of miR-21′s role in CVDs, addressing its potential as a diagnostic biomarker and therapeutic target. We discuss recent advancements, limitations, and future prospects in miR-21 research, emphasizing the importance of integrating this knowledge into clinical practice to improve CVD management.</div></div>","PeriodicalId":10205,"journal":{"name":"Clinica Chimica Acta","volume":"574 ","pages":"Article 120304"},"PeriodicalIF":3.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842710","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}

This approach provides an in-depth view of cellular activities and protein interactions, offering unprecedented insights into cancer progression and treatment. Unlike traditional methods that investigate specific pathways in isolation, proteomics enables simultaneous analysis of thousands of proteins, generating a comprehensive understanding of cancer biology.

The conventional methods for KP identification are characterized by intricacy and suboptimal efficiency.

To minimize the likelihood of aerosol-based contamination, the RPA components are positioned at the base of the tube, while the CRISPR/Cas12a components are placed at the tube’s cap. The systems are combined post-RPA amplification through a brief centrifugation step, ensuring that RPA reactions are conducted independently to produce an adequate amount of target DNA before interaction with the CRISPR/Cas12a system. This method was validated using both fluorescent and lateral flow strip assays, achieving a limit of detection (LOD) of 10<sup>0</sup> copies/μL and 10<sup>1</sup> copies/μL respectively. The specificity for KP detection was found to be 100 %. Furthermore, the system demonstrated a positivity rate of 78 % (18/23) when directly extracting DNA from sputum samples, corroborated by culture and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS).
