Analytical challenges and technical limitations in assessing circulating miRNAs.
نویسندگان
چکیده
MiRNAs are emerging as promising biomarkers in cardiovascular diseases and may constitute a novel mechanism of intercellular communication. Accurate quantification of circulating miRNAs is essential. A variety of technological approaches and platforms have been developed with increased sensitivity and specificity for the detection and quantification of circulating miRNAs. In this review, we focus on the technical aspects and discuss the analytical challenges in profiling circulating miRNAs.

A Review of the Function of Circulating Cell Free miRNAs as Promising Biomarkers in Cancer Diagnosis, Treatment, and Metastasis
Cell Free miRNAs are small, non-coding molecules that can be secreted into the bloodstream in very stable forms. These types of miRNAs, like intracellular miRNAs, participate in the control of many biological processes and are expressed in both natural and pathological conditions. Quantitative and qualitative changes in expression of circulating miRNAs are associated with the onset and progress...
متن کاملChallenges in Using Circulating miRNAs as Cancer Biomarkers
In the last years, circulating miRNAs have emerged as a new class of promising cancer biomarkers. Independent studies have shown the feasibility of using these small RNAs as tools for the diagnosis and prognosis of different types of malignancies as well as for predicting and possibly monitoring treatment response. However, despite an initial enthusiasm for their possible clinical application, ...

MicroRNAs (miRNAs) are severely protected sequences and single stranded structures approximately 18 to 25 nucleotides in length. The crucial role of miRNAs has been previously proved in the regulation of the gene expression in post transcriptional modification events of messenger RNA. The precise mechanism by which miRNAs modulate translational repression of mRNAs is not fully determined. Howev...
