In this paper, 4 microRNAs and their targets were predicted through a de novo prediction procedure in the genome of Porcine Reproductive and Respiratory Syndrome virus. Through clustalW analysis, these 4 microRNAs were recognized as novel PRRSV derivate microRNAs. Target prediction results showed PRRSV mir-1, 2 and 4 have total 16 targets in porcine 3’ UTR database. These targets could be divid...

Circulating microRNAs have been recognized as promising biomarkers for the detection of lung cancer. The objective of this study was to evaluate miR-10b, miR-1 and, miR-30a in the plasma samples of lung cancer patients to confirm any possible relevance in the early detection of lung cancer. Plasma samples from 47 non-small-cell lung cancer patients and 41 cancer-free subjects were evaluated for...

it was known that il-1β-induced rapid expression of mir-146a, which regulated the secretion of inflammatory chemokines in human a549 alveolar epithelial cells. however, little is known about the level of primary mir-146a and the downstream biogenesis of mir-146a in a549 cells. we examined the levels of primary mir-146a and mature mir-146a in a549 cells following treatment with pharmacological i...

background: type 1 diabetes (t1d) is caused by cell-mediated autoimmune attack on pancreatic beta-cells. previous studies highlight the role of micrornas (mirnas) in the pathogenesis of t1d. mirnas are small non-coding rnas involved in the regulation of gene expression post-transcriptionally. in this work, mir-18b was chosen and the differential expression of it was measured between t1d patient...

objective(s):micrornas (mirnas) are a class of short rnas that control the biological processes including cell proliferation, apoptosis and development. aberrant expression of mirnas was determined in the different stages of tumor development and metastasis. to study the effect of silibinin on mirnas expression, we evaluated quantitative expression of mir-21 and mir-155 as two oncomirs and seve...

MicroRNAs are non-coding RNAs. Studies have shown that miRNAs are expressed aberrantly in stroke. MiR-1 enhances ischemic damage, and previous study has demonstrated that reduction of miR-1 level has neuroprotective effect on Middle Cerebral Artery Occlusion(MCAO). Since apoptosis is one of the important process in neural protection, possible effect of miR-1 on this pathway has been tested in t...
