RATIONALE MicroRNAs modestly suppress their direct mRNA targets, and these direct effects are amplified by modulation of gene transcription pathways. Consequently, indirect mRNA modulatory effects of microRNAs to increase or decrease mRNAs greatly outnumber direct target suppressions. Because microRNAs are products of transcription, the potential exists for microRNAs that regulate transcription...
identification and characterization of liver micrornas of the chinese tree shrew via deep sequencing
conclusions according to the liver microrna data of chinese tree shrew, characteristics of the mir-122 and let-7 families further highlight the suitability of tree shrew as the animal model in hcv research. objectives this study aimed to construct a liver microrna (mirna) data of the tree shrew. materials and methods three second filial generation tree shrews were used in this study. total rna ...
Abstract Introduction MicroRNAs are promising biomarkers of renal disease, however the cellular origin their expression is usually unclear limiting interpretation when measured in biopsies and urine. We hypothesised that by first defining cell-enriched microRNAs, we could select based on expected histopathological profile. Method Small RNA-sequencing cortical, proximal tubular (LTL), macrophage...
micrornas (mirnas) are non-coding small rna molecules with 21–25 nucleotides. it plays significant role in control of gene expression at posttranscriptional/translational level. they are commonly dysregulated in human cancers, whereas they may behave either as oncogenes or as tumor-suppressor genes. both genetic and epigenetic events in deregulation of mirna can lead to cancer development. gene...
MicroRNAs are abundant small non-coding RNA with a variety of known functions, including transcriptional activation and inhibition. Recent evidence has suggested that microRNA expression may influence the responsiveness some cancers to chemotherapy, liver lung cancers. Some now specific microRNAs, such as miR-21, miR-155, miR-375, oral cancer chemotherapy – although much remains be discovered. ...
mirs are 17-25 nucleotide non-coding rnas. these rnas target approximately 80% of protein coding mrnas. mirs control gene expression and altered expression of them affects the development of cancer. mirs can function as tumor suppressor via down-regulation of proto-oncogenes and may function as oncogenes by suppressing tumor suppressors. myeloproliferative neoplasias (formerly known as chronic ...
Amniotic fluid (AF) continuously exchanges molecules with the fetus, playing critical roles in fetal development especially via its complex components. Among these components, microRNAs are thought to be transferred between cells loaded in microvesicles. However, the functions of AF microRNAs remain unknown. To date, few studies have examined microRNAs in amniotic fluid. In this study, we emplo...
