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...

Summary

This summary is machine-generated.

We developed Cell Type Aware analysis of RNA-seq (CARseq) to accurately analyze gene expression in mixed cell samples. CARseq improves differential expression analysis and identifies cell types contributing to disease, like in schizophrenia and autism.

Area of Science:

Bioinformatics
Genomics
Computational Biology

Background:

Tissue samples contain diverse cell types, complicating differential gene expression analysis.
Existing methods struggle to distinguish cell type composition effects from cell type-specific expression changes.

Purpose of the Study:

Introduce Cell Type Aware analysis of RNA-seq (CARseq), a novel computational framework.
Address limitations in analyzing RNA-seq data from heterogeneous tissues.
Improve accuracy in identifying differentially expressed genes and underlying cell type contributions.

Main Methods:

CARseq utilizes a negative binomial distribution for modeling RNA-seq count data.
The framework integrates cell type composition into differential expression analysis.
Simulation studies were performed to evaluate CARseq's performance.

Main Results:

CARseq demonstrates significantly higher statistical power compared to linear model-based approaches.
CARseq provides more accurate rankings of differentially expressed genes.
Application to schizophrenia and autism data identified key cell types involved in these neurodevelopmental diseases.

Conclusions:

CARseq effectively accounts for cell type heterogeneity in RNA-seq data.
The method accurately identifies cell type-specific expression changes and their role in disease.
CARseq findings align with single-cell RNA-seq analyses, validating its utility.
