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...

Background:

High-throughput RNA sequencing generates dynamic expression data crucial for understanding cellular responses.
Current analysis methods for RNA sequencing data often treat selection, clustering, and functional analysis as independent steps.
This fragmented approach fails to fully leverage the integrated information across analysis stages.

Purpose of the Study:

To develop an integrated R package, FunPat, for analyzing time series RNA sequencing data.
To combine gene selection, clustering, and functional annotation into a unified analytical framework.
To enhance the identification of differentially expressed genes by exploiting functional annotations and common dynamic expression profiles.

Main Methods:

FunPat is an R package designed for time series RNA sequencing data analysis.
It integrates gene selection, clustering, and functional annotation into a single pipeline.
The package performs integrated selection-clustering analysis for each functional term to identify differentially expressed genes with shared temporal profiles and annotations.

Main Results:

FunPat improves recall in gene selection without increasing the false discovery rate compared to standalone selection.
The package demonstrates high precision and recall in identifying correct temporal expression patterns, outperforming other clustering methods.
FunPat provides reproducible gene lists even in the absence of biological replicates and enhances result interpretability.

Conclusions:

A novel analysis pipeline, FunPat, was developed to identify temporal patterns in functionally annotated gene sets.
The integration of differential expression evidence, temporal profiles, and functional annotations enhances gene selection sensitivity.
FunPat improves result readability by associating significant genes with informative functional terms and representative temporal patterns.
