Gene expression informatics - it's all in your mine

Technologies for whole-genome RNA expression studies are becoming increasin gly reliable and accessible. However, universal standards to make the data more suitable for comparative analysis and for inter-operability with other information resources have yet to emerge. Improved access to large electro nic data sets, reliable and consistent annotation and effective tools for ' data mining' are critical. Analysis methods that exploit large data warehou ses of gene expression experiments will be necessary to realize the full po tential of this technology.
