Overall goal

Development of a dedicated bioinformatics platform, loaded with tools and methods which allow wetlab biologists to interpret their own high-throughput experiments (mircoarray data,chip on chip, whole genome sequencing). 

Reaching this goal

R2 is our in house developed web-based bioinformatics analysis and visualization platform that enables analysis of probable targets in the context of (tumor) microarray data (url: http://r2.amc.nl). Specifically focusing at biologists, R2 aids in the analysis and visualization of microarray data (tumor series, experiments) and their annotated features (such as clinical information). R2 contains an expanding set of analyses which are heavily inter-connected, allowing users to quickly hop from one view (representation of the data) to another. Currently R2 supports all major chip designs for human, mouse and rat and harbors nearly 30.000 microarray samples (divided over more than 250 datasets). R2 is also being employed in the integration, analysis and visualization of aCGH / ChIP on chip / Whole genome sequence information.

Public use of the project results

The main research-objective of our group is the fast translation of probable drug targets for childhood tumors from the wet-lab to the clinic. The tools developed are used to determine these targets.
