Optimal management of patients with thyroid cancer requires the use of sensitive and specific biomarkers. For early diagnosis and effective follow-up, the currently available cytological and serum biomarkers, thyroglobulin and calcitonin, present severe limitations. Research on microRNA expression in thyroid tumors is providing new insights for the development of novel biomarkers that can be used to diagnose thyroid cancer and optimize its management. In this review, we will examine some of the methods commonly used to detect and quantify microRNA in biospecimens from patients with thyroid tumor, as well as the potential applications of these techniques for developing microRNA-based biomarkers for the diagnosis and prognostic evaluation of thyroid cancers...

MicroRNAs (miRNAs) are a class of small noncoding RNAs that act mainly as negative regulators of gene expression. Several studies demonstrated that miRNAs take part in numerous biological processes, such as proliferation, apoptosis, and migration. The dysregulation of miRNAs has been frequently observed in different types of disease, including cancer. Here, we provide a comprehensive review on the human miR-193a-3p by considering its role in both physiological and pathological contexts. Different mechanisms involved in regulating miR-193a-3p expression have been reported, including epigenetic modifications and transcription factors...

In recent years, there has been increasing interest in finding new biomarkers for diagnosis and prognostication of liver diseases. MicroRNAs (miRNAs) are small noncoding RNA molecules involved in the regulation of gene expression and have been studied in relation to several conditions, including liver disease. Mature miRNAs can reach the bloodstream by passive release or by incorporation into lipoprotein complexes or microvesicles, and have stable and reproducible concentrations among individuals. In this review, we summarize studies involving circulating miRNAs sourced from the serum or plasma of patients with nontumoral liver diseases in attempt to bring insights in the use of miRNAs as biomarkers for diagnosis, as well as for prognosis of such diseases...

Quiescence (G0) is defined as an assortment of cell cycle arrested states that exhibit distinct properties. Leukemias harbor a subpopulation of G0 cells that can be enriched by growth factor deprivation or serum starvation. Target site reporters with shortened poly(A) tails show translation activation by microRNAs, via a noncanonical mechanism, when introduced into the nucleus of G0 cells. This is because recruitment by the activation causing FXR1a-microRNA-protein complex (FXR1a-microRNP) is nuclear and requires shortened poly(A) tails to avoid repressive factors and canonical translation...

MicroRNAs (miRNAs) are small RNAs that bind to mRNA targets and regulate their translation. A functional study of miRNAs and exploration of their utility as disease markers require miRNA extraction from biological samples, which contain large amounts of interfering compounds for downstream RNA identification and quantification. The most common extraction methods employ silica columns or the TRIzol reagent but give out low recovery for small RNAs probably due to their short strand lengths. Herein, we fabricated the titanium dioxide nanofibers using electrospinning to facilitate miRNA extraction and developed the optimal buffer conditions to improve miRNA recovery from biological matrices of cell lysate and serum...

Transcatheter aortic valve implantation (TAVI) is the method of choice in patients with high risk or contraindications for conventional aortic valve replacement. However, it is not well understood which parameters predict the overall cardiac function post- procedurally. MicroRNAs (miRNA/ miR) are small non-coding RNA molecules that repress gene expression by different mechanisms and can also be detected in the blood. Recent studies have shown that miRNAs detected in the blood may serve as sensitive and specific biomarkers in various diseases, therefore we examined the levels of different microRNAs in the serum of patients undergoing TAVI...
