A new study suggests that gene expression profiling may allow researchers to track the progression of bovine spongiform encephalopathy (BSE) in cattle and ultimately predict their infectious status.

The findings are detailed in the September issue of the Journal of Virology.

"Gene expression profiling in the BSE time course study revealed a broad correlation between the expression of genes and the progression of BSE," say the researchers. "Evidence is presented to suggest that it is possible to predict the infectious status of animals using the expression profiles from this study."
