RNA-seq of wild-type Salmonella Typhimurium SL1344 in the presence and absence of chlorpromazine or Phe-Arg-Beta-Napthylamide

The aim of this experiment was to determine the changes in transcription caused by inhibition of efflux pumps by the Phe-Arg-Beta-Naptylamide (PABN) and chlorpromazine. Four biological replicates per condition were grown to mid-log phase in MOPS minimal media (OD600) and were exposed to the known efflux inhibitor PABN, and the proposed efflux inhibitor chlorpromazine at 100 µg/ml and 50 µg/ml, respectively. Exposure lasted for two hours. Total RNA was extracted and DNase-treated. The samples were sent to BGI, Hong Kong for sequencing by Illumina Hiseq 4000.
