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 microarray-based...

Background:

Next-generation sequencing (NGS) advances transcription factor binding site (TFBS) identification.
Bioinformatics analysis of large ChIP-seq datasets presents a significant challenge for researchers.
Extracting biological insights from experimental data is often hindered by complex data analysis.

Purpose of the Study:

To develop integrated peak-calling and analysis software (Sole-Search) for user-friendly ChIP-seq data analysis.
To overcome the roadblock of false positives in TFBS identification.
To provide automated, web-based access to genomic analysis tools for investigators.

Main Methods:

Developed Sole-Search, a web-based, automated software with a user-friendly interface.
Integrated peak-calling and statistical analysis for ranked TFBS identification.
Enabled data conversion for genome browser visualization and comparison of experimental overlaps.

Main Results:

Sole-Search outputs ranked peak locations with reduced false positives.
The software identifies nearest genes, classifies peak locations relative to gene structure, and quantifies binding sites.
Analysis of amplified and deleted genomic regions is performed.
Demonstrated utility with ChIP-seq data for six human transcription factors/cell lines.

Conclusions:

Sole-Search provides a robust, automated solution for ChIP-seq data analysis.
The software facilitates easier and more immediate access to biological insights from genomic experiments.
Sole-Search overcomes key bioinformatics challenges in TFBS identification and analysis.
