Genomic Location and Intensity of Transcription of Non-coding RNA Regulation Candidates in Porphyromonas gingivalis

Many pathogens are bacteria and antibiotic resistance is increasing. The development of novel treatments is hampered by a poor understanding of the mechanisms of their regulation. Specifically, non-coding RNAs play an important role in the internal regulation of bacteria. To further the investigation of non-coding RNA and pathogenicity, RNA sequencing data for PorX/PorY dependent regulation in P. gingivalis, a Gram negative oral pathogen was studied. The PorX/PorY two component regulatory system controls phenotypes for this bacteria's virulence including an important type IX secretion system for gingipain proteases, which degrades host cytokines, down regulating the host response by reducing inflammation. This study compared transcription of non-coding RNA in wild type and PorX knockout mutant strain, in the 33277 strain and the more virulent W83 strain in both liquid and solid cultures to identify and categorize loci of genomic sequence for further study of porX/porY regulation.
