The fates of RNA species in a cell are controlled by ribonucleases, which degrade them by exploiting the universal structural 2′-OH group. This phenomenon plays a key role in numerous transformative...

Transcript’s abundance is typically considered a proxy of the corresponding genes transcriptional activity. Yet, a poorly transcribed gene could see many of its RNA molecules accumulate just because they are highly stable. Conversely, if a gene is very actively transcribed ...

RNA-seq is a well-established method for studying the transcriptome. Popular methods for library preparation in RNA-seq such as Illumina TruSeq® RNA v2 kit use a poly-A pulldown strategy. Such methods can cause loss of coverage at the 5′ end of ...

Transcription of eukaryotic genomes produces protein-coding mRNAs and diverse noncoding RNAs (ncRNAs), including enhancer RNAs (eRNAs). Most ncRNAs are rapidly degraded, difficult to detect, and thus far have not been mappable in their full range. Mapping of transient RNAs is ...

Integrity of the mRNA in clinical samples has major impact on the quality of measured expression levels. This is independent of the measurement technique being next generation sequencing (NGS), Quantitative real-time PCR (qPCR) or microarray profiling. If mRNA is highly ...

The enormous number of public gene expression data sets can turn into research gold when mined for any number of biological questions. But digging into the data of other researchers is often fraught by a lack of metadata. In particular, ...

Histone epigenome data determined by chromatin immunoprecipitation sequencing (ChIP-seq) is used in identifying transcript regions and estimating expression levels. However, this estimation does not always correlate with eventual RNA expression levels measured by RNA sequencing (RNA-seq). Part of the inconsistency ...
