MicroRNAs (miRNAs) are ~22-nucleotide-long small non-coding RNAs that regulate the expression of protein-coding genes by base pairing to partially complementary target sites, preferentially located in the 3´ untranslated region (UTR) of target mRNAs. The expression and function of miRNAs have ...

Massively parallel strand-specific sequencing of RNA (ssRNA-seq) has emerged as a powerful tool for profiling complex transcriptomes. However, many current methods for ssRNA-seq suffer from the underrepresentation of both the 5′ and 3′ ends of RNAs, which can be attributed ...

The past decade has seen an explosion of interest in cataloging the small RNA repertoires of animal and plant species, and in understanding the biological function of small RNAs. Small RNAs include not only microRNAs, but also piRNAs and other ...
Read More »miRNEST 2.0 – a database of plant and animal microRNAs
Ever growing interest in microRNAs has immensely populated the number of resources and research papers devoted to the field and, as a result, it becomes more and more demanding to find miRNA data of interest. To mitigate this problem, researchers ...
Read More »Significant Technical Variations in Low-Input RNA-seq Methodologies
Recent advances in RNA-seq methodologies from limiting amounts of mRNA have facilitated the characterization of rare cell-types in various biological systems. So far, however, technical variations in these methods have not been adequately characterized, vis-à-vis sensitivity, starting with reduced levels ...
