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...

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features....

Simulation of ChIP-seq data using known binding templates.
Validation with publicly available datasets (Oct4, Sox2).
Compatibility testing with multiple sequencing platforms (Illumina, Roche454, Ion Torrent, SOLiD) and ChIP-Exo.

Main Results:

isChIP accurately approximates real ChIP-seq protocols and generates similar data.
The software successfully modeled diverse binding events, including transcription factors and chromatin modifiers.
Comparative analysis demonstrated isChIP's superiority over existing simulators.
isChIP supports various sequencing platforms and ChIP-Exo.
