Summary
This study implements a caGrid application for designing and analyzing cancer epigenetics microarray experiments. The service-oriented approach enhances flexibility and integration of diverse data sources for research.
Area of Science:
- Bioinformatics
- Cancer Research
- Genomics
Background:
- Designing custom microarray experiments for cancer epigenetics requires integrating diverse data types and datasets.
- Existing infrastructure may lack flexibility for dynamic data integration and analysis.
Purpose of the Study:
- To implement a caGrid-based application supporting the design and analysis of custom microarray experiments for cancer epigenetics research.
- To leverage a service-oriented architecture for flexible integration of data and analytical resources.
Main Methods:
- Utilized caGrid, the service-oriented Grid software infrastructure of the NCI cancer Biomedical Informatics Grid (caBIG).
- Implemented data sources as caGrid Data Services.
- Wrapped analytical resources as caGrid Analytical Services.
Main Results:
- The service-based implementation allows backend resources to be modified or upgraded independently.
- Remote resources can be easily added without centralizing infrastructure.
- Facilitates the synthesis of information from multiple data types and datasets for complex analyses.
Conclusions:
- The caGrid application provides a flexible and scalable platform for cancer epigenetics research using microarray data.
- Service-oriented architecture enhances the adaptability and extensibility of bioinformatics applications.
- This approach supports custom experimental design and analysis by integrating distributed resources effectively.

DNA Microarrays
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...
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...

Genome Annotation and Assembly
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
