This study makes a significant advancement on a microRNA amplification technique previously used for expression analysis and sequencing in animal models without annotated mature microRNA sequences. As research progresses into the post-genomic era of microRNA prediction and analysis, the need for a rapid and cost-effective method for microRNA amplification is critical to facilitate wide-scale an...

miRBase is the primary online repository for all microRNA sequences and annotation. The current release (miRBase 16) contains over 15,000 microRNA gene loci in over 140 species, and over 17,000 distinct mature microRNA sequences. Deep-sequencing technologies have delivered a sharp rise in the rate of novel microRNA discovery. We have mapped reads from short RNA deep-sequencing experiments to mi...

It has been reported that increasingly microRNAs are associated with diseases. However, the patterns among the microRNA-disease associations remain largely unclear. In this study, in order to dissect the patterns of microRNA-disease associations, we performed a comprehensive analysis to the human microRNA-disease association data, which is manually collected from publications. We built a human ...

Purpose: To investigate the effect of microRNA-16 (miR-16) on glioma cell migration and invasiveness, mechanism involved.Methods: MicroRNA-16 mimic or inhibitor was transfected into human (SHG44) cells. Cell migration, invasiveness morphology were determined using scratch test, Transwell invasion assay, immunohistochemical staining, respectively. Expressions bcl-2, MMP-9 MMP-2, NF-κB1 proteins ...

Accumulating evidence indicates that numerous microRNAs are involved in the tumorigenesis and progression of gastric cancer, while the clinical significance of microRNA-214 in gastric cancer is poorly understood and the exact role of microRNA-214 in gastric cancer remains obscure. In the present study, expression levels of microRNA-214 in 80 gastric carcinoma tissues, 18 nontumourous gastric ti...

MicroRNAs have been appreciated in various cellular functions, including the regulation of angiogenesis. Mesenchymal-stem-cells (MSCs) transplanted to the MI heart improve cardiac function through paracrine-mediated angiogenesis. However, whether microRNAs regulate MSC induced angiogenesis remains to be clarified. Using microRNA microarray analysis, we identified a microRNA expression profile i...

background: microrna is a type of small rna of about 22 nucleotide length. most popular mirnas are found in the liver and are extensively important in determining the biological and clinical functions. microrna, in host cells, may impact the replication of viruses either positively or negatively. in this study the mir-122 expression was examined and compared in three groups, two sample groups o...

micrornas are tiny, 18-25 nucleotides in length, non-coding rna molecules preserved throughout evolution. these molecules primarily control gene expression at the post-transcriptional and transcriptional levels. micrornas control target gene expression by a phenomenon known as rna interference. rna interference based therapeutics that utilize target gene silencing/degradation by specific micror...
