MiRNAs high throughput sequencing profiling of basals cells and columnar cells

ABSTRACT: The airway mucociliary epithelium is consituted of three main cell types : columnar ciliated plus secretory cells and basal cells. Columnar cells are represented by a great majority of ciliated cells. We used Cell sorting by FACSaria to separate basal cells from ciliated and secreting columnar cells. Then, we performed microRNA high throughput sequencing to investigate the specific signature of microRNA of basal and columnar cells.

miRNAs high throughput sequencing profiling of regenerating human airway epithelial cells

Project description:The regeneration of the airway mucociliary epithelium involves several sequential events including migration, proliferation, polarization and final differentiation (i.e ciliogenesis). The airway mucociliary epithelium is consituted of three main cell types : ciliated cells, secretory cells and basal cells. We used microRNA microrrays to investigate the signature of microRNA during the four step of regeneration of the airway epithelium.

microRNAs signatures of Xenopus laevis embryo epidermis at stage 11 (non ciliated) and 26 (ciliated) using high throughput sequencing

Project description:Epidermis of Xenopus embryos forms a mucociliary epithelium constituted of basal, scattered, secreting and ciliated cells and is histologically similar to human airway mucociliary epithelium. We compared microRNAs signatures of epidermis of Xenopus embryos at stage 11.5 (gastrula, non ciliated epidermis) and at stage 26 (tailbud, ciliated epidermis). 2 technical replicates of a pool of 50 explants for each stage 11.5 (non ciliated) and 26 (ciliated) of Xenopus laevis development

PAX2-null progenitors define multiple lineages with common expression signatures in benign and neoplastic oviductal epithelium

Project description:The oviducts contain high grade serous cancer precursors, which are M-NM-3-H2AXp and p53 mutation positive. Secretory cell outgrowths (SCOUTs) are associated with older age and serous cancer. We evaluated PAX2 expression in proliferating oviductal cells, normal mucosa, SCOUTs, Walthard cell nests, STINs and HGSCs. Non-ciliated cells in normal mucosa were PAX2 positive but became PAX2 negative in multilayered epithelium. PAX2 negative SCOUTs fell into two groups; Type I were secretory or secretory/ciliated with a M-bM-^@M-^\tubalM-bM-^@M-^] phenotype and were ALDH1 negative. Type II displayed a columnar to pseudostratified phenotype, with an EZH2,ALDH1, M-NM-2-catenin, Stathmin, LEF1, RCN1 and RUNX2 expression signature . This study, for the first time, links PAX2 negative with proliferating fetal and adult oviductal cells undergoing basal and ciliated differentiation and shows that this expression state is maintained in SCOUTs, STINs and HGSCs. All three entities can demonstrate a consistent perturbation of genes involved in potential tumor suppressor gene silencing (EZH2), transcriptional regulation (LEF1), regulation of differentiation (RUNX2) calcium binding (RCN1) and oncogenesis (Stathmin). This shared expression signature between benign and neoplastic entities links normal progenitor cell expansion to abnormal and neoplastic outgrowth in the oviduct and exposes a common pathway that could be a target of early prevention. 17 total samples are analyzed. 4 for TYPE 1 SCOUTs, 3 for TYPE 2 SCOUTs, 7 for paired normal epithelium, 3 for tumor

Expression data from airway basal cells and mucociliary-differentiated epithelium of COPD patients and normal subjects

Project description:Continuous stress caused by smoking induces changes in the cell population of small airway epithelium, with basal cell hyperplasia and goblet cell metaplasia at the expense of ciliated cells, and there is now compiling evidence that basal cells play a key role in the early pathogenesis of Chronic Obtructive Pulmonary Disease (COPD). We hypothesized that COPD airway basal cells undergo transcriptomic changes during differentiation that are different from those observed in normal cells and can explain the formation of an abnormal epithelium. We performed microarray analysis of basal cells obtained from healthy non-smoker and COPD subjects and also mucociliary-differentiated cell cultures from the same basal cells. We compared the transcriptome of normal and COPD basal cells, mucociliary-differentiated normal and COPD cell cultures and also of basal cells with corresponding mucociliary-differentiated cultures for both normal and COPD.
