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...

iChip

iChip

The cultivation of environmental microorganisms has long been hindered by the inability to replicate complex native conditions in vitro. The isolation chip (iChip) addresses this limitation by facilitating the growth of previously uncultivable microorganisms through in situ incubation. Designed for high-throughput microbial cultivation, the iChip comprises hundreds of microchambers, each capable of housing a single microbial cell. These microchambers are loaded with a mixture of molten agar and...

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.

Background:

Chromatin immunoprecipitation (ChIP) is crucial for understanding genome regulation.
Analyzing ChIP data, especially from ChIP-sequencing (ChIP-seq), requires specialized bioinformatics tools.
Existing tools may not fully address the complexities of both ChIP-chip and ChIP-seq data.

Purpose of the Study:

To introduce CisGenome, a comprehensive software system for genome-wide ChIP data analysis.
To provide integrated tools for visualization, normalization, peak detection, and motif analysis.
To support both ChIP-chip and ChIP-seq methodologies, including advanced statistical methods for ChIP-seq.

Main Methods:

Development of a modular software system, CisGenome.
Implementation of statistical methods for ChIP-seq data analysis.
Integration of a built-in browser for visualizing various genomic data types.

Main Results:

CisGenome offers a user-friendly graphic interface and batch-mode computation.
The software successfully visualizes array images, signals, gene structure, conservation, and sequence/motif information.
Demonstrated utility through comparative ChIP-chip/ChIP-seq analysis and motif discovery.

Conclusions:

CisGenome provides a versatile platform for analyzing genome-wide ChIP data.
The software facilitates comprehensive analysis from raw data to motif discovery.
CisGenome supports both established and novel ChIP-based genomic research.
