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...

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...

Area of Science:

Genomics
Molecular Biology
Bioinformatics

Background:

Long-read single-cell RNA sequencing (scRNA-seq) offers advanced gene expression insights beyond gene-level analysis.
Existing analytical methods for scRNA-seq are limited, necessitating new tools for isoform analysis.

Purpose of the Study:

To introduce IsoDiffR, a novel computational tool for identifying RNA isoforms with distinct expression patterns in scRNA-seq data.
To enable identification of cell-type-specific isoforms and facilitate comparisons across multiple cell types.

Main Methods:

Development of IsoDiffR, an R package for analyzing long-read scRNA-seq data.
Benchmarking IsoDiffR using simulated data.
Application of IsoDiffR to scRNA-seq data from Macaca fascicularis corneal limbus and human frontal cortex.

Main Results:

IsoDiffR successfully identified previously unrecognized cell-type-specific isoforms in both animal and human datasets.
The tool detected isoforms not discernible through conventional analytical approaches.
Exploration of identified isoforms' structural and functional properties revealed potential biological roles.

Conclusions:

IsoDiffR provides a robust methodological framework for investigating isoform-specific functions at the single-cell level.
The findings offer new perspectives on gene expression regulation and isoform diversity in complex biological systems.
