Project description:S. flexneri infected Henle-407 cells were treated with and without 20 mM formate, RNA-seq was used to determine transcriptome changes
Project description:We evaluated the transcriptome changes induced by infection of Hela 229 cells with Shigella flexneri. The sample set consists of a control (mock), total population of infected sample and infected sample sorted into Shigella positive and Shigella negative population.
Project description:Comparison of wild type S. flexneri 2457T gene expression to deletion mutant of S. flexneri 2457T gene S4473 at three growth phases and intracellularly
Project description:Berberine is a natural isoquinoline alkaloid found in Chinese medicinal herbs which is active against a variety of microbial infections. To examine the potential effects of berberine on Shigella flexneri, a whole-genome DNA microarray was constructed and transcriptome analysis of the cellular responses of S.flexneri when exposed to Berberine Chloride (BC) was performed.
Project description:Comparison of wild type S. flexneri 2457T gene expression to deletion mutant of S. flexneri 2457T gene S4473 at three growth phases and intracellularly Broth culture was grown to mid-log in LB, intracellular growth was 3 hours post invasion of HCT-8 cell (colonic epithelial cell line).
Project description:This experiment was designed to identify IFNg-regulated, IRF1-dependent genes during infection with the intracellular pathogen Shigella flexneri. WT and Irf1-/- MEFs were stimulated for 18 hours with IFNg or left unstimulated; all of the cells were subsequently infected for 6 hours with S. flexneri prior to harvest of total RNA.
Project description:In most eukaryotes and bacteria, queuosine (Q) replaces the guanosine at the wobble position of tRNAs harboring a GUN anticodon. To faithfully detect Q-modification in RNAs from Schizosaccharomyces pombe and Shigella flexneri, Q-MaP-Seq was established and applied to tRNAs from S. pombe WT (AEP1) cells and Shigella flexneri WT cells and tgt∆ cells. Q-modification of in vitro-transcribed RNAs and RNAs isolated from S. pombe and S. flexneri followed by reverse transcription using the RT-active DNA polymerase variant RT-KTq I614Y and sequencing of unmodified compared to modified RNAs allowed identification of Q-sites within tRNAs.
Project description:To find the alterations of expression profiles of shigella flexneri, we performed DNA chip analysis and proteomic analysis at the same time.
Project description:We performed a systemic study of the poloxamer P-407-induced chronic hyperlipidemia in C57BL/6J mice. Mice were treated 96 days every third day.The poloxamer mostly elevates plasma triglycerides and cholesterol while change of the liver cholesterol is not significant.
