(Submitter supplied) This data set is part of a larger study: Variants of microRNAs, (isomiRs) are commonly reported in deep-sequencing studies; however the functional significance of these variants remains controversial. To assess their biological relevance, we have performed ultra-deep miRNA-seq on ten adult human tissues, and created an analysis pipeline (miRNA-MATE) to align, annotate, and analyze miRNAs and their isomiRs. more...

(Submitter supplied) Variants of microRNAs, (isomiRs) are commonly reported in deep-sequencing studies; however the functional significance of these variants remains controversial. To assess their biological relevance, we have performed ultra-deep miRNA-seq on ten adult human tissues, and created an analysis pipeline (miRNA-MATE) to align, annotate, and analyze miRNAs and their isomiRs. We find that isomiRs share sequence and expression characteristics with canonical miRNAs, and are generally strongly correlated with canonical miRNA expression. more...

(Submitter supplied) We performed deep sequencing of small RNA from mouse insulinoma (MIN6) cells cultured in 25mM glucose. We then developed and implemented an in-house short-read mapping strategy to analyze isomiR diversity.

(Submitter supplied) MicroRNAs (miRNAs) are a class of small RNA molecules that regulate expression of specific mRNA targets. They can be released from cells, often encapsulated within extracellular vesicles (EVs), and therefore have the potential to mediate intercellular communication. It has been suggested that certain miRNAs may be selectively exported, although the mechanism has yet to be identified. Manipulation of the miRNA content of EVs will be important for future therapeutic applications. more...

(Submitter supplied) Mouse Embryonic Stem (ES) cells express a unique set of microRNAs (miRNAs), the miR-290-295 cluster. To elucidate the role of these miRNAs and how they integrate into the ES cell regulatory network requires identification of their direct regulatory targets. The difficulty, however, arises from the limited complementarity of metazoan miRNAs to their targets, with the interaction requiring as few as six nucleotides of the miRNA seed sequence. more...

(Submitter supplied) MicroRNAs (miRNAs) are single-stranded non-coding RNAs that negatively regulate target gene expression through mRNA cleavage or translational repression. There is mounting evidence that they play critical roles in heart disease. The expression of known miRNAs in the heart has been studied at length by microarray and quantitative PCR but it is becoming evident that microRNA isoforms (isomiRs) are potentially physiologically important. more...

(Submitter supplied) We performed extensive transcriptome analysis of the tiger pufferfish (Takifugu rubripes) using the next-generation sequencer SOLiD III, and profiled millions of small RNA sequences in somatic tissues and gonads, as well as identifying thousands of miRNAs. The number of miRNAs identified was the highest in fish species reported to date. We also report highly variable isomiR features.

(Submitter supplied) Pig mRNAs Ensembl transcripts (Ver. 56) and UniGene (Ver. 38) sequences were used to produce a dedicated microarray platform to analyze mRNAs gene expression. Based on sequence similarity we rejected UniGene features that overlapped more than 40% with an Ensembl transcript. After this filter we obtained 40,267 UniGene clusters and 19,603 Ensembl transcripts (protein coding + pseudogenes + retrotransposed elements). more...

(Submitter supplied) The short length of miRNAs results in a high dynamic range of melting temperatures and therefore impedes a proper selection of detection probes or optimized PCR primers. While miRNA microarrays allow for massive parallel and accurate relative measurement of all known miRNAs, they have so far been less useful as an assay for absolute quantification. Here we developed a new method based not only to the hybridization process that presents the limits before described, but integrating the hybridization to an enzymatic reaction. more...

(Submitter supplied) We applied a new computational approach to predict specie-specific and conserved miRNAs, than experimentally confirmed by a modified RNA-primed Array-based Klenow Extension (RAKE) method. We identified 489 conserved and 1,178 pig-specific novel miRNAs increasing our tally of confirmed miRNAs to 1,667 novel miRNAs. In addition, RAKE allowed the identification of miRNA isoforms (isomiRs) that we demonstrated to be differentially expressed across tissues suggesting that subtle variability in isomiR expression is regulated and biologically meaningful.
