Comparative expression profile of Porphyromonas gingivalis parent strain W83 and the HU protein (PG0121) mutant during exponential growth in rich medium.. Porphyromonas gingivalis

HU protein regulates expression of genes involved in cell-division, iron acquisition, and transcriptional regulation in Porphyromonas gingivalis Overall design: Analysis involved RNA extracted from the parent strain W83 and the PG0121 (HU protein) mutant during exponential growth in rich medium. Each of the four experiments used a different preparation of RNA. Comparative expression profiles were determined by hybridizing the microarray slide with a mixture containing equal amount of cDNA generated from each strain. Dye swap experiments were performed.
