Project description:In this project we investigated the effect of sub lethal doses of the novel antibiotic 3-bromo-PP on the proteome of S. aureus Mu50.
Project description:We have used a Schistosoma japonicum infected murine model with in vivo sub-lethal dosages of praziquantel against adult parasites. Differential gene expression of parasites was followed between 30 minutes and 24 hours post- drug administration, using a whole transcriptome microarray platform. Differential gene expression was considered separately between parasite gender.

Differential gene expression of parasites was followed between 30 minutes and 24 hours post- drug administration, using a whole transcriptome microarray platform. Differential gene expression was considered separately between parasite gender. Total RNA was isolated from adult (7 week post cercarial challenge) Schistosoma japonicum male and females. Gene expression was determined through hybridisation on an Agilent custom designed oligo microarray.
Project description:The continued emergence of Neisseria gonorrhoeae (Ng) isolates resistant to first-line antibiotics has focused efforts on understanding how alternative therapies such as expanded use of gentamicin (Gen) might counteract this global public health problem. Focusing on Gen as a possible alternative antibiotic for treatment of gonorrheal infections, we used RNA-Seq to determine if sub-lethal levels of Gen might impact gonococci on a transcriptional level. We found that sub-lethal Gen altered expression of a finite number of genes in gonococcal strain FA19. Many of the differentially regulated genes were associated with known stress responses elaborated by Ng under different harmful conditions. Within the Gen regulon, we found that the hicAB operon, which encodes the putative HicAB toxin-antitoxin system, was transcriptionally activated in response to Gen.
Project description:Transcriptional profiling of SMMC-7721 cells comparing control untreated with sub-lethal heat treated cells (50°C for 10 min). Differentially expressed lncRNA and mRNA were measured with an Agilent Human lncRNA+mRNA Array V4.0 (4 × 180 K format) containing 41,000 lncRNAs and 34,000 mRNAs. Goal was to determine the effects of sub-lethal heat treatment on global hepatoma carcinoma cells gene expression.
Project description:To see the effect of sub-lethal concentration of tobramcyin on PAO1 under anaerobic conditions. RNA was isolated from 5 biological repeats of PAO1 grown to mid-log phase in cationic adjusted mueller hinton broth containing 15mM KNO3 and 5 biological repeats of PAO1 grown to mid-log phase in cationic adjusted mueller hinton broth containing 15mM KNO3 and then treated for 30 minutes with 2 ug/ml tobramycin. All flasks were sealed to create anaerobic conditions. null
