RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

RNA Editing

RNA Editing

RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Background:

RNA-editing, a post-transcriptional modification by ADAR and APOBEC enzymes, regulates diverse cellular functions.
Over 300,000 RNA-editing sites exist in the human genome, with most occurring under specific conditions.
RNA-sequencing (RNA-seq) is crucial for RNA-editing detection and prediction, but prone to false positives.

Purpose of the Study:

To develop a computational tool for accurate RNA-editing detection from RNA-seq data.
To distinguish true RNA-editing events from technical artifacts.
To facilitate the study of condition-specific RNA-editing.

Main Methods:

Development of RDDpred, a Random Forest classifier for RNA-editing detection.
Utilizing RNA-seq data for prediction.
Automated compilation of condition-specific training examples.

Main Results:

RDDpred successfully identified true RNA-editing sites with high accuracy (90%, 95%) in validation datasets.
The tool demonstrated strong performance in rejecting false discoveries (NPV: 75%, 84%).
RDDpred automates the creation of training data, eliminating the need for experimental validation.

Conclusions:

RDDpred is the first automated machine-learning pipeline for RNA-editing site prediction.
This tool significantly aids in the study of condition-specific RNA-editing.
RDDpred is publicly available for research use.
