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...

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...

Background:

Ribosome profiling (Ribo-seq) is crucial for studying translation regulation.
It measures translation efficiency and reveals local regulatory patterns.
Existing computational tools lack methods for differential pattern testing in Ribo-seq data.

Purpose of the Study:

To introduce RiboDiPA, a novel R package for Differential Pattern Analysis of Ribo-seq data.
To enable rigorous statistical testing of ribosome footprint pattern differences.
To identify genes with significant changes in ribosome occupancy patterns.

Main Methods:

Development of a novel computational approach for Ribo-seq data analysis.
Implementation of the approach as an R package named RiboDiPA.
Validation using simulated and benchmark Ribo-seq datasets.

Main Results:

RiboDiPA enables rapid identification of differential ribosome occupancy patterns.
Differential pattern analysis provides complementary information to translation efficiency analysis.
The method successfully uncovers meaningful pattern differences across biological conditions and at single codon resolution.

Conclusions:

RiboDiPA offers a robust method for analyzing Ribo-seq data patterns.
It enhances the understanding of translational regulation beyond efficiency metrics.
The tool is applicable to various model organisms from yeast to mammals.
