Transcriptional analysis of AI-2 treatment in Yersinia pestis at 30°C

ABSTRACT: Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of autoinducer-2 (AI-2) quorum sensing was investigated by comparing transcript profiles when AI-2 quorum-sensing signal is added in to control. The strain Δpgm (pigmentation-negative) mutant was used as wild type.The control consisted of cells grown and treated under the same conditions without added signals.

Transcriptional analysis of AI-2 treatment in Yersinia pestis at 30Â°C

Project description:Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of autoinducer-2 (AI-2) quorum sensing was investigated by comparing transcript profiles when AI-2 quorum-sensing signal is added in to control. The strain Îpgm (pigmentation-negative) mutant was used as wild type.The control consisted of cells grown and treated under the same conditions without added signals. Six independent RNA samples from Y. pestis CO92 Îpgm cultures were paired with six independent RNA samples from AI-2 signal added in cultures for hybridization to six two-color microarrays. A dye-swap design was used to remove the Cy5 and Cy3 dye bias.

Here, the process of autoinducer-2 (AI-2) quorum sensing was investigated by comparing transcript profiles when AI-2 quorum-sensing signal is added in. The strain M-bM-^HM-^Fpgm(pigmentation-negative) mutant R88 was used as wild type. The control consisted of cells grown and treated under the same conditions without added signals. Six independent RNA samples from Y. pestis CO92 M-bM-^HM-^Fpgm cultures were paired with six independent RNA samples from AI-2 signal added cultures for hybridization to six two-color microarrays. A dye-swap design was used to remove the Cy5 and Cy3 dye bias.

Transcriptional analysis of luxS-null strain in Yersinia pestis CO92 at 37°C

Project description:Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of autoinducer 2 (AI-2) quorum sensing was investigated by comparing transcript profiles when luxS gene was knocked out. The luxS gene encodes S-ribosylhomocysteinase which can produce DPD, a precursor of AI-2. The strain ∆pgm (pigmentation-negative) mutant R88 was called wild type. The ∆pgm ∆luxS mutant was called control.

Project description:Yersinia pestis, the etiological agent of plague, is able to sense cell density by quorum sensing. The function of quorum sensing in Y. pestis is not clear. Here, the process of quorum sensing was investigated by comparing transcript profiles when three quorum-sensing signals are added in. The strain M-bM-^HM-^Fpgm (pigmentation-negative) mutant R88 was used as wild type. The three signals are AI-2, AHLs (N-(3-Oxooctanoyl)-L-homoserine lactone and N-Hexanoyl-DL-homoserine lactone).The control consisted of cells grown and treated under the same conditions without added signals. Six independent RNA samples from Y. pestis CO92 M-bM-^HM-^Fpgm cultures were paired with six independent RNA samples from 3 signals added cultures for hybridization to six two-color microarrays. A dye-swap design was used to remove the Cy5 and Cy3 dye bias.

Transcriptional analysis of ypeIR mutation in Yersinia pestis at 37°C

Project description:The etiologic agent of bubonic plague, Yersinia pestis, senses cell density-dependent chemical signals to synchronize transcription between cells of the population in a process named quorum sensing. Though the closely related enteric pathogen Y. pseudotuberculosis uses quorum sensing system to regulate motility, the role of YpeIR quorum sensing in Y. pestis has been unclear. YpeIR is one of the AHL quorum sensing system in Y. pestis. In this study we performed transcriptional profiling experiments to identify Y. pestis YpeIR quorum sensing regulated functions at 37°C.
