RNA Interference

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Ribosomal RNA Synthesis

Ribosomal RNA Synthesis

Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Experimental RNAi

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Background:

Short RNA sequencing data reveals post-transcriptional processing events.
MicroRNA arm switching exemplifies differential processing across tissues.

Purpose of the Study:

To analyze short RNA genomic loci for differential or coherent processing across nine ENCODE cell lines.
To identify novel instances of differential RNA processing.

Main Methods:

Analysis of short RNA sequencing data from ENCODE cell lines.
Computational pipeline for identifying differential and coherent processing patterns.

Main Results:

Differential processing was predominantly observed in microRNAs (miRNAs), small nucleolar RNAs (snoRNAs), and transfer RNAs (tRNAs).
Four known differentially processed miRNAs were recovered, and several novel cases were identified.
Coherent processing was widespread in both annotated and unannotated regions, with unannotated loci showing enrichment for ~17 nt RNAs characteristic of transcription initiation RNAs.

Conclusions:

The study successfully identified differential and coherent RNA processing events using a novel computational pipeline.
The findings expand the understanding of RNA processing variations and their potential regulatory roles.
The developed pipeline is applicable to other RNA sequencing datasets for broader transcriptome-wide studies.
