Project description:We analyzed ~27nt small RNAs from Entamoeba histolytica trophozoites in basal conditions and after heat shock or oxidative stress E. histolytica trophozoites were treated with 1mM H2O2 for 1hr, or heat shocked at 42°C for 1hr and RNA was isolated and small RNA populations were compared to small RNA populations from untreated trophozoites
Project description:We analyzed ~27nt small RNAs from Entamoeba invadens trophozoites, 24h cysts, 72h cysts, and excysting cells (8h) E. invadens trophozoites were induced to encyst by incubation in low glucose media, and parasites harvested at 0, 24 and 72h. A subset of the 72h cysts were induced to excyst, and parasites harvested at 8h. Total RNA was extracted for each sampleand small RNA libraries constructed and sequenced as below
Project description:We provided a full spectrum analysis for E. histolytica AGO2-2 associated 27nt small RNAs. Additionally, comparative analysis of small RNA populations from virulent and non-virulent amebic strains indicates that small RNA populations may regulate virulence genes. AGO2-2 bound small RNAs from E. histolytica strain HM-1:IMSS were immunoprecipitated and sequenced using 454 technology. Three independant sequencing runs were perfomed using the same RNA sample. In addition, size selected small RNAs from E. histolytica strain Rahman were sequenced with the same technology. One sequencing run was performed on this sample.
Project description:Tn insertion library was used for recipient for conjugative transfer of pESBL, F, and R388 plasmids. For both recipient and the resulting exconjugant libraries, Tn insertion sites were determined by illumina sequencing
Project description:incubation for 15 min and 30 min of human liver sinusoidal cell cultures with virulent or virulence-attenuated Entamoeba histolytica or incubation without parasites added
Project description:2 million E. histolytica HM1:IMSS was treated with 0.5% DMSO for 3 h and 2 million E. histolytica HM1:IMSS was treated with 1 M-5M auranofin for 3 h
Project description:The main goal of this study was to analyse gene expression change of virulent amoebic strain (i.e. HM1:IMSS) in different environmental contexts, including isolation from animal liver, contact with the human colon and short prolonged in vitro culture.
Project description:Honey bee drones, queens and workers have vastly different phenotypes. Here we profile the the expression level of mRNAs and microRNAs of honeybee, drones, queens and workers at the L5 larval stage (91 hours +/- 1). For both mRNA and miRNA, we analyse five replicates for drones, queens and workers (15 replicates for mRNA and 15 for miRNA).
