The effect of hfq on global gene expression and virulence in Neisseria gonorrhoeae

ABSTRACT: Hfq is an RNA chaperone, which functions as a pleiotropic regulator for RNA metabolism in bacteria. To characterize the role of Hfq in pathogenicity of Neisseria gonorrhoeae we generated a N. gonorrhoeae hfq mutant, MS11hfq.Transcriptional analysis using a custom-made N. gonorrhoeae microarray revealed that 369 open reading frames were differentially regulated in MS11hfq compared to the wild-type (wt) strain (202 were upregulated, 167 were downregulated). Arrays were generated as custom 8x15 K microarrays (Agilent Technologies) covering all open reading frames (ORFs) from N. gonorrhoeae strain FA1090 (accession number AE004969) supplemented with all ORFs from the gonoccoccal genetic island of strain MS11 (accession number AY803022) by 6 specific 60-mer oligonucleotides per gene on average
