1. ABSTRACT

Microarrays are now routinely employed to characterize gene expression of thousands of genes from a single hybridization. The genome wide gene expression profile aids in the understanding of genes that may be regulated in a particular pathological condition. This paper provides an overview of microarray technology and its recent developments followed by its usage in studies of cardiovascular disease and how it pertains to viral and parasitic infections of the heart.
