LC SciencesIn the past, differential profiling and functional studies of microRNA (miRNA) has been performed mainly using tissues samples collected by invasive methods. However, in a clinical setting, more convenient and non-invasive methods are required, such as collection of peripheral blood or other bodily fluids. Recently, it has been demonstrated that miRNAs are present in circulating blood plasma, both free circulating and within exosomes, as well as within other biofluids such as cerebral spinal fluid, urine and even breast milk. These circulating miRNAs represent a potential new approach for diagnostic screening.

LC Sciences and Norgen Biotek are conducting a free webinar focusing on the recent developments and current practices for profiling of extracellular microRNAs.

Implication of Sperm RNA in Transgenerational Inheritance of the Effects of Early Trauma in Mice

Recent studies have suggested that early-life stressors and traumatic experiences can cause heritable changes in gene expression in future generations. Researchers at the University of Zurich’s Brain Research Institute hypothesized that early-life stressors in male mice may cause heritable changes in the small, non-coding RNA content (including miRNAs) in the sperm of traumatized mice and that this may induce behavioral changes in future progeny. Using RNA-Seq, global miRNA content in male sperm of controls and a model system of males subjected to unpredictable maternal separation combined with unpredictable maternal stress (MSUS) had significantly altered expression patterns. Additionally, miRNA in the sperm of MSUS mice exhibited altered miRNA expression in the serum and hippocampus. The changes in miRNA expression were similar in the serum and the hippocampus of F2 progeny of the MSUS males compared to control. However, the miRNA expression levels in F2 sperm were similar to normal controls. Despite this, F2 and F3 progeny exhibited [click to continue…]


mrSNP workflowmrSNP is a highly adaptable and performing web based tool for predicting the effect a 3′UTR SNP will have on miRNA binding. This tool has advantages over existing algorithms because it can assess the effect of novel SNPs on miRNA binding without requiring significant hands on time.

MicroRNAs (miRNAs) bind to sites in the 3′untranslated regions (3′UTR) of a targeted messenger RNA (mRNA). Binding leads to degradation of the transcript or blocked translation resulting in decreased expression of the targeted gene. Single nucleotide polymorphisms (SNPs) have been found in 3′UTRs that disrupt normal miRNA binding or introduce new binding sites and some of these have been associated with disease pathogenesis. This raises the importance of detecting miRNA targets and [click to continue…]


Next-gen Sequencing and ncRNA, small RNA, miRNA data analysis workshopThe organizers are happy to announce the upcoming “NGS and non-coding RNA data analysis” workshop II (2014) 15-16 May, Plovdiv, Bulgaria

The SeqAhead COST action BM1006 is organizing a 2 day workshop with presentations on non-coding RNA (ncRNA) research, bioinformatics, data analysis and stimulating discussions between biologists and bioinformaticians. The registration for this COST WS is now open.

The Workshop will concentrate on current topics in NGS and non-coding RNAs, with special emphasis on data analysis. The ultimate goal of the workshop is to bring software developers, bioinformaticians and experimental scientists together, bridging the gap between users’ needs and developers’ goals.

Workshop Target:

-biologists with research in ncRNA (ncRNA, small RNAs, miRNAs) applying or planning to apply Next Generation Sequencing technologies
-bioinformaticians involved in data analysis or developing algorithms for data analysis of ncRNA data.

The workshop is open for everybody in the ncRNA and NGS field. The workshop is free of charge and participants have to pay their own hotel and travel. COST will offer travel reimbursement to some selected researchers and you will need to provide a poster abstract.

MicroRNA 491-3p & Pharmacogenetics: Regulation of UDP-Glucuronosyltransferase 1A1 Expression and Activity

February 10, 2014

The goal of pharmacogenetics is to better understand human response to both environmental toxins and drug treatment. Recently, several laboratories have investigated the hypothesis that microRNA regulation of drug metabolizing enzymes may influence their expression and ultimately effect enzymatic activity and patient drug toxicities. Researchers at the Pennsylvania State Hershey College of Medicine and Washington […]
