MicroRNAs have emerged as important regulators of the metastatic process. In addition, circulating miRNAs appear to be surprisingly stable in peripheral blood making them ideal noninvasive biomarkers for disease diagnosis. Here, we performed a proof-of-principle study investigate expression profile and their association with lymph node status early breast cancer patients. Sentinel was detected ...

The Ras homolog (Rho) family of small GTPases comprise several proteins with prominent roles in regulation cell cycle transition, migration, and remodeling actin cytoskeleton. Expression these is regulated by factors among them are long non-coding RNAs (lncRNAs). impact lncRNAs on Rho signaling can be exerted through direct modulation expression or influencing miRNAs that negatively regulate GT...

Objective(s): To investigate the effect of miR-103 on the angiogenesis of ischemic stroke rats via targeting vascular endothelial growth factor (VEGF) at the molecular level. Materials and Methods: Rat models had received the middle cerebral artery occlusion (MCAO) or sham operation before grouping, and cell models of oxygen-glucose deprivation (OGD) were performed. FITC-dextran, matrigel, and ...

Background and Aims: Chronic lymphocytic leukemia (CLL) is the most common adult human leukemia. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression. Research has shown that in CLL, microRNAs can have function as oncogenes or tumor suppressors. Some studies demonstrated that the expression of microRNA-93 (miR-93) and microRNA-330 (miR-330) have been changed in several can...

ackground: Gene expression profiling distinguishes the absence or presence of moderate to severe grades of acute cellular rejection in cardiac allograft recipients using a 20-gene classifier. We explored the hypothesis that the rejection classifier also differentiates various forms of mild rejection and we performed sub-analyses based on time post-transplant and confirmatory pathology interpret...

Identifying immunocompromised women who are at risk of developing cervical cancer remains a challenge for clinicians. In an effort to identify the role HIV in carcinogenesis, this study evaluated levels normally downregulated oncomirs (miR-21, miR-146a, miR-155, miR-182, and miR-200c) upregulated tumor suppressors (miR-let-7b, miR-125b, miR-143, miR-145, p53 expression) associated with serum li...

One of the mechanisms for development autoimmune diseases is changes in epigenetic regulation, root causes which have not yet been established. At same time, data on role transposons as sources long noncoding ribonucleic acids (RNA) and microRNAs involved immune pathology accumulated. In evolution, transposable elements become basis emergence V(D)J recombination regulation HLA genes. Pathologic...

Breast cancer is a leading cause of related death among women worldwide and it complex disease characterized by its heterogeneity. The heterogenous characteristic the breast responsible for aggressiveness treatment resistance. stem cells (BCSCs) are population with increased propensity proliferation, differentiation, migration, invasion mammosphere formation resistance to treatment. They have a...
