DDT • Volume 10, Number 18 • September 2005 REVIEWS Using microarray gene signatures to elucidate mechanisms of antibiotic TODAY:TARGETS DRUG DISCOVERY action and resistance Reviews • Michelle and Robert Microarray analyses reveal global changes in gene expression in response to environmental changes and, thus, are well suited to providing a detailed picture of bacterial responses to antibiotic treatment. These responses are represented by patterns of gene expression, termed expression signatures, which provide insight into the mechanism of action of antibiotics as well as the general physiological responses of bacteria to antibiotic-related stresses. The complexity of such signatures is challenging the notion that antibiotics act on single targets and this is consistent with the concept that there are multiple targets coupled with common stress
