Abstract

BACKGROUND: The rising drug resistance in pathogenic bacteria and inefficiency of current antibiotics to meet clinical requirements has augmented the need to establish new and innovative approaches for antibacterial drug discovery involving identification of novel antibacterial targets and inhibitors. Being obligatory for bacterial growth, essential gene products are considered vital as drug targets. The bacterial protein YidC is highly conserved among pathogens and is essential for membrane protein insertion due to which it holds immense potential as a promising target for antibacterial therapy. METHODS/PRINCIPAL FINDINGS: The aim of this study was to explore the feasibility and efficacy of expressed antisense-mediated gene silencing for specific downregulation of yidC in Escherichia coli. We induced RNA silencing of yidC which resulted in impaired growth of the host cells. This was followed by a search for antibacterial compounds sensitizing the YidC depleted cells as they may act as inhibitors of the essential protein or its products. The present findings affirm that reduction of YidC synthesis results in bacterial growth retardation, which warrants the use of this enzyme as a viable target in search of novel antibacterial agents. Moreover, yidC antisense expression in E. coli resulted in sensitization to antibacterial essential oils eugenol and carvacrol. Fractional Inhibitory Concentration Indices (FICIs) point towards high level of synergy between yidC silencing and eugenol/carvacrol treatment. Finally, as there are no known YidC inhibitors, the RNA silencing approach applied in this study put forward rapid means to screen novel potential YidC inhibitors. CONCLUSIONS/SIGNIFICANCE: The present results suggest that YidC is a promising candidate target for screening antibacterial agents. High level of synergy reported here between yidC silencing and eugenol/carvacrol treatment is indicative of a potential antibacterial therapy. This is the first report indicating that the essential gene yidC is a therapeutic target of the antibacterial essential oils eugenol and carvacrol in E. coli.

  • Decreasing YidC expression made E. coli more sensitive to the activity of carvacrol and eugenol.

    “Patil et al. [91] explored the feasibility and efficacy of using antisense-mediated gene silencing to specifically down-regulate YidC in E. coli and found that decreasing YidC expression made the microorganism more sensitive to the activity of carvacrol and eugenol.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
