Small RNA Modifications: Integral to Function and Disease

Small RNA-mediated epigenetic modifications in plants.

Epigenetic modifications in plants can be directed and mediated by small RNAs (sRNAs). This regulation is composed of a highly interactive network of sRNA-directed DNA methylation, histone, and chromatin modifications, all of which control transcription. Identification and functional characterization of components of the siRNA-directed DNA methylation pathway have provided insights into epigene...

Small interfering RNA; principles, applications and challenges--

Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...

Chimira: analysis of small RNA sequencing data and microRNA modifications

UNLABELLED Chimira is a web-based system for microRNA (miRNA) analysis from small RNA-Seq data. Sequences are automatically cleaned, trimmed, size selected and mapped directly to miRNA hairpin sequences. This generates count-based miRNA expression data for subsequent statistical analysis. Moreover, it is capable of identifying epi-transcriptomic modifications in the input sequences. Supported m...
