The potential use of miRNAs in the diagnosis and prediction of metastatic lung carcinoma.
Lung carcinoma is the "top killer" of all malignancies in the world. Early diagnosis of lung carcinoma significantly improves patient survival. Screening with biomarkers from peripheral blood could detect more patients at an early stage of the disease. MicroRNAs (miRNAs) could be a possible biomarker. These are 21-23 nucleotide long single-stranded RNA molecules playing an important role in the post-transcriptional regulation of gene activity. Individual miRNAs have the potential to regulate genes responsible for cell proliferation, differentiation, apoptosis, regulate cell cycle in cooperation with pro-oncogenes and tumor suppressor genes. In our study, we determined miRNA expression levels in individual samples of lung carcinoma patients and in a healthy control group. We used the reverse transcription method followed by qRT-PCR. The expression levels of the investigated miRNAs were evaluated in the QIAGEN GeneGlobe Data center software. We demonstrated the significance of miR-126 and let-7g as biomarkers of lung carcinoma in all clinical stages studied. We also observed significantly increased expression of miR-143 and miR-145 at the distant metastasis stage, and significantly decreased expression of miR-133a in the N2 disease group of lung carcinoma patients (N2 disease represents disease with metastases in the ipsilateral mediastinal and/or subcarinal lymph nodes or node). The investigated miRNAs showed no clear potential for detecting potentially resectable (N0-N1), locally advanced (N2) and distant organ metastatic (M1) lung carcinoma.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
