Project description:We used next generation sequencing to analyze the effects of Zika virus (ZIKV) strains Uganda and French Polynesia on intracellular and extracellular vesicle (EV) derived miRNA profiles of induced pluripotent stem cell-derived human neural stem cells (long-term self-renewing neuroepithelial-like stem (lt-NES®) cells) - particularly to identify dysregulated miRNAs which are associated with the microcephaly phenotype.
Project description:We used whole genome expression profiling to analyze the effects of Zika virus (ZIKV) strains Uganda and French Polynesia on the mRNA transcriptome of induced pluripotent stem cell-derived human neural stem cells (long-term self-renewing neuroepithelial-like stem (lt-NES®) cells) - particularly to identify differentially expressed genes which are associated with microcephaly phenotype.
Project description:Non-targeted LC-MS/MS of PPL extracts from experimental and environmental seawater samples from coral reefs from Mo'orea (French Polynesia), collected in May 2019.
Project description:Antibiotic resistance associated with the expression of the clinically significant carbapenemases, IMP, KPC, and NDM and OXA-48 in Enterobacteriaceae is emerging as a worldwide calamity to health care. In Australia, IMP-producing Enterobacteriaceae is the most prevalent carbapenemase-producing Enterobacteriaceae (CPE). Genomic characteristics of such carbapenemase-producing Enterobacteriaceae (CPE) are well described, but the corresponding proteome is poorly characterised. We have thus developed a method to analyse dynamic changes in the proteome of CPE under antibiotic pressure. Specifically, we have investigated the effect of meropenem at sub-lethal concentrations to develop a better understanding of how antibiotic pressure leads to resistance. Escherichia coli, producing either NDM, IMP or KPC type carbapenemase were included in this study, and their proteomes were analysed in growth conditions with or without meropenem.
Project description:The increasing resistence and/or bacterial tolerance to bactericides, such as chlorhexidine, causes worrisome public health problems. Using transcriptomical and microbiological studies, we analysed the molecular mechanisms associated with the adaptation to chlorhexidine in two carbapenemase-producing strains of Klebsiella pneumoniae belonging ST258-KPC3 and ST846-OXA48.
