ABSTRACT: Transcription profiling by array of human gingival epithelial cells infected with Aggregatibacter actinomycetemcomitans or Porphyromonas gingivalis
Project description:In this study, we performed a miRNA global profiling in human lung epithelial cells (A549) infected by two different subtypes of human influenza A viruses (H1N1 and H3N2). A549 cells were either mock-infected or infected at a multiplicity of infection (MOI) of 1 with H1N1 or H3N2 viruses, and total RNAs were isolated at 24 hours post-infection (hpi). An MOI of 1 was performed to ensure that 100% of the cells were infected at 24 hpi, a strategy that we have previously validated and used for a transcriptional profiling study of infected cells (Josset et al. , 2010). The purified RNAs were subjected to reverse transcription using a pool of miRNA RT primers (Human pool A v2.1, Applied Biosystems) and subsequently amplified and quantified by RT-qPCR in a TaqMan array MicroRNA card (Applied biosystems).
Project description:Real-time quantitative PCR analysis of human epithelial cells The activity of Malva sylvestris extract and fractions infected by A. actinomycetemcomitans were investigated using an adapted dual chamber model, oral human epithelial cells were used in the co-culture model. One microgram of RNA was converted in cDNA using RT2 First Strand Kit. 84 genes were analyzed using inflammatory response & Autoimmunity Array RT2 profiler (Qiagen Sabiosciences, Valencia, CA, USA) with buffers supplied by the manufacturer qPCR gene expression profiling. Oral human epithelial cells were infected by A. Actinomycetemcomintans and treated with Malva sylvestris extract and fractions prior to gene expression analysis.
Project description:Human coronary artery endothelial cells were infected with Chlamydophila pneumoniae. We monitor cellular gene expression profiling altered by life cycle of Chlamydophila pneumoniae using Affymetrix Human Genome U133 Plus 2.0 Array.

Project description:In the present study, we discovered an unexpected interplay between immunometabolism and antiviral immunity. Profiling of human bronchial epithelial BEAS-2B cells was performed using Agilent’s SurePrint G3 human gene expression microarray kit. A single-color design provided two types of comparison: (i) IAV-infected versus mock-infected cells, and (ii) succinate-treated infected cells versus mock-infected cells.
