Discordant Expression of Circulating microRNA from Cellular and Extracellular Sources
نویسندگان
چکیده
MicroRNA (miRNA) expression has rapidly grown into one of the largest fields for disease characterization and development of clinical biomarkers. Consensus is lacking in regards to the optimal sample source or if different circulating sources are concordant. Here, using miRNA measurements from contemporaneously obtained whole blood- and plasma-derived RNA from 2391 individuals, we demonstrate that plasma and blood miRNA levels are divergent and may reflect different biological processes and disease associations.

Evaluation of Extracellular Circulating Human MicroRNA-197 as a Target Biomarker in Patients with Coronary Artery Disease
Background: Coronary Artery Disease (CAD) refers to the reduction or blockage of all or part of the coronary arteries due to the process of atherosclerosis or the presence of a clot. The aim of this study was to investigate the association of serum miR-197 as a diagnostic index in patients with coronary artery disease. Methods: In this study, 100 patients with CAD were selected. Extraction of...
متن کاملMicroRNAs as a New Molecular Biomarker for Diagnosis and Prognosis of T-cell Acute Lymphoblastic Leukemia (T-ALL): A Systematic Review
MicroRNAs (miRNAs, miRs) are small endogenous non-coding RNAs that regulate the expression of protein-encoding genes at the post-transcriptional level. Several studies have described the role of miRNAs in T-cell acute lymphoblastic leukemia (T-ALL), including tumor suppressor and oncogenic miRNAs. Down-regulation of miRNA expression is a prominent feature of human malignancy. This down-regulati...

Background: The immune-mediated responses in vascular cells may include the increased expression of endothelial adhesion molecules, leukocyte rolling and infiltration, cellular lipid dysregulation and vascular smooth muscle cells (VSMCs) differentiation. Investigating the cellular and molecular events involved in the rolling process is useful for treatment or prevention of the vessel stenosis es...

MicroRNAs (miRNAs) represent a class of small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. They play a crucial role in diverse cellular pathways. Ionizing radiation (IR) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. Recently it has been discovered that mi...

Background and Aims: Polycystic ovary syndrome (PCOS) has a largely unknown etiology and is a common heterogeneous endocrine disorder in women of reproductive age, characterized by polycystic ovaries, hyperandrogenism, insulin resistance, and chronic anovulation. MicroRNAs (miRNAs) are small, noncoding RNA sequences that negatively regulate gene expression at the post-transcriptional level. miR...
