Global gene expression profiling of M. tuberculosis H37Rv and the isogenic regX3-inactivated mutant (DregX3) grown in phosphate enriched or phosphate-limited medium. Global gene expression profiling of M. tuberculosis H37Rv and the isogenic regX3-inactivated mutant (DregX3) grown in phosphate enriched or phosphate-limited medium

In order to understand the repertoire of genes regulated by RegX3, we performed microarray analysis of gene expression in M. tuberculosis (WT) or DregX3 grown in phosphate-enriched or phosphate limited medium. The differentially regulated genes provide insight into the role of RegX3 in gene regulation in Mtb. Overall design: Gene expression profiling was performed in replicates for both the wild type and the isogenic DregX3 grown in phosphate enriched or phosphate limited conditions.
