context:micrornas (mirnas) are a class of short, endogenously-initiated, non-coding rnas that post-transcriptionally control gene expression via translational repression or mrna turnover. mirnas have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. the molecular mechanisms underlying t...

acute coronary syndrome is the leading cause of mortality worldwide. for prompt diagnosis and management of this disease, several biomarkers have been utilized. recently microrna which are suggestive of tissue damage and some are cardiospecific are paid special attention and might help in dearly diagnosis of this disease and furthermore help in preventing the resultant mortality. in this review...

PURPOSE MicroRNAs are approximately 22 nucleotide noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was (a) to determine a role of microRNA-21 in esophageal squamous cell carcinoma and (b) to elucidate the regulation of the programmed cell death 4 (PDCD4) gene by microRNA-21. EXPERIMENTAL DESIGN MicroRNA-21 expression was investigated in 20 mat...

Purpose. Oncolytic Reoviruses, as a self-limiting virus, can be used in cancer treatment, because they have the ability to replicate tumor cells selectively and destroy them. Studies show that some immune response proteins may interfere with virus life cycle. So, main aim of this bioinformatic study is check which microRNA able target reovirus inhibitory proteins. Experimental Design. By use on...

The aim of this study was to identify potential microRNAs and genes associated with drug resistance in ovarian cancer through web-available microarrays. The drug resistant-related microRNA microarray dataset GS54665 and mRNA dataset GSE33482, GSE28646, and GSE15372 were downloaded from the Gene Expression Omnibus database. Dysregulated microRNAs/genes were screened with GEO2R and were further i...

MicroRNAs play critical roles in the occurrence and progression in various cancers including colorectal cancer. Here, we found that microRNA-30a expression was significantly downregulated in colorectal cancer tissues compared to adjacent noncancerous tissues, and the suppression levels of microRNA-30a were significantly associated with tumor differentiation and lymph node metastasis. We also di...

'miR2Disease', a manually curated database, aims at providing a comprehensive resource of microRNA deregulation in various human diseases. The current version of miR2Disease documents 1939 curated relationships between 299 human microRNAs and 94 human diseases by reviewing more than 600 published papers. Around one-seventh of the microRNA-disease relationships represent the pathogenic roles of ...

Molecular epidemiological studies suggest that microRNA polymorphisms may be associated with an increased risk of coronary heart disease (CHD). However, the results of these studies were inconsistent and inconclusive. To derive a more precise evaluation, we performed a meta-analysis focused on the associations between microRNA polymorphisms and CHD risk. PubMed, Embase, CNKI and Wanfang databas...
