Transcription profiling of human erythroid cell differentiation

Project description:Human mononuclear cells were cultured in 2 phases. In the 1st phase the culture medium contained cyclosporine A the 2nd phase contained SCF and erythropoietin. Cells were collected at 3 stages of differentiation; on day 6, 10, 12 and represented early erythroblasts, medium stage and normoblasts. Experiment Overall Design: RNA was extracted from each sample of cells at a different stage of differentiation and subjected to microarray studies in duplicates.

The NFIA-ETO2 fusion blocks terminal erythroid maturation and induces pure erythroid leukemia (PEL) in cooperation with mutant TP53

Project description:The NFIA-ETO2 fusion is the product of a t(1;16)(p31;q24) chromosomal translocation so far exclusively found in pediatric patients with pure erythroid leukemia (PEL). To address its role for the pathogenesis of the pure erythroid leukemia, we retrovirally expressed the PEL-associated NFIA-ETO2 fusion or an in active NFIA-ETOdeltaNHR4 mutant in primary erythroblasts in fetal liver-derived erythroblasts from either wild-type (C57/B6) or TP53R248Q (HUPKI) mice. Gene expression was determined by RNA sequencing from cells kept in maintenance medium (MM) or 24h in differentiation-inducing medium (DM)

Comparative analysis of therapeutic effects between medium cut-off and high flux dialyzers using metabolomics and proteomics

Project description:This study compared the therapeutic effects of medium cut-off (MCO) and high flux (HF) dialyzers using metabolomics and proteomics. This was a single-center prospective trial of 20 patients receiving maintenance hemodialysis (HD). A consecutive dialyzer membrane was used for 15-week study periods as follows: 1st HF dialyzer, MCO dialyzer, 2nd HF dialyzer, for 5 weeks respectively. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was used to identify proteins.

Project description:The NFIA-ETO2 fusion is the product of a t(1;16)(p31;q24) chromosomal translocation so far exclusively found in pediatric patients with pure erythroid leukemia (PEL). To address its role for the pathogenesis of the pure erythroid leukemia, we retrovirally expressed the PEL-associated NFIA-ETO2 fusion in primary erythroblasts in fetal liver-derived erythroblasts from wild-type (C57/B6) mice. To better characterize alteration in chromatin accessibility due to NFIA-ETO2 expression, we analyzed accessible chromatin state by ATAC sequencing from cells kept in 24h in differentiation-inducing medium (DM)

Transcription profiling of mouse erythroblasts during erythroid differentiation

Project description:The I/11 and R10 erythroid progenitor cell line was cultivated in serum free medium (StemPro34) supplemented with Epo (0,5U/ml), SCF (100ng/ml) and dexamethasone (10-6M). To identify genes specifically regulated by Epo/SCF-induced polysome recruitment, cells were factor deprived for 4h and subsequently treated for 2h with 5U/ml Epo and 200ng/ml SCF or left untreated. Subsequently we isolated both total and polysome bound mRNA from each condition, which was hybridised to oligonucleotide arrays (Affymetrix). Analysis of data with Rosetta Resolver allowed to identify and compare Epo/SCF induced gene expression in total and polysome bound RNA. To assess gene expression during erythroid differentiation, cells were induced to differentiate in presence of 5U/ml Epo and 0.5mg/ml Fe-loaded transferrin. Polysome bound mRNA was isolated from cells proliferating in presence of Epo, SCF and dexamethasone (renewal conditions), and from cells induced to differentiate for 48h or 60h.

EP001: The interferon transcriptome in uterine NK cells is upregulated during the second trimester of pregnancy allowing extravillous trophoblast invasion

Project description:Uterine Natural Killer (uNK) cells regulate essential developmental processes at the maternal-fetal interface during early pregnancy. Uterine NK cell functions are tightly regulated during early placentation to stimulate trophoblast invasion and remodel uterine spiral arteries. Access to human 1st and 2nd trimester uterine tissues allowed us to investigate the transcriptional changes in uNK cells during the early stages of early human pregnancy. Microarray analysis identified 97 upregulated genes in 2nd compared to 1st trimester purified uNK cells of which the majority (61%) clustered as interferon-stimulated-genes (ISG), with ISG15 and ISG20 being upregulated profoundly. Type I interferons (IFNα/β), but not type II interferon (IFNɣ) increased expression of the identified interferon target genes ISG15 and ISG20 in uNK cells in vitro. Moreover, the cytokine-like protein ISG15 stimulated in vitro trophoblast invasion. Second trimester uNK cells promoted trophoblast invasion in vitro, whereas both 1st and 2nd trimester uNK cells stimulated endothelial tube formation. IFNα but not IFNβ stimulation of 1st trimester uNK cells enhanced their capacity to promote trophoblast invasion. In conclusion, the uNK cell interferon transcriptome is upregulated during the 2nd trimester allowing uNK cells to promote trophoblast invasion. Type I interferon signaling regulates uNK cell-induced trophoblast invasion via induction of effector molecules like ISG15. First trimester uNK cells can be induced to act like second trimester uNK cells by IFNα with respect to promotion of trophoblast invasion. Key words: Gene expression profiling ■ uterine natural killer cells ■ extravillous trophoblast invasion ■ interferon alpha ■ ISG15

Seq-Scope: Submicrometer-resolution spatial barcoding technology that enables microscopic examination of tissue transcriptome at single cell and subcellular levels

Project description:Purpose: we propose Sequence-Scope (Seq-Scope), which can generate ultra-high definition images of sequence-based molecular signatures resolved at a submicrometer scale. Experimental Methods: Seq-Scope experiment is divided into two consecutive sequencing steps: 1st-Seq and 2nd-Seq. 1st-Seq of Seq-Scope starts with the solid-phase amplification of a single-stranded synthetic oligonucleotide library using an Illumina sequencing-by-synthesis (SBS) platform. 2nd-Seq of Seq-scope begins with overlaying the tissue section slice onto the HDMI-array. Computational Methods: Tissue boundaries are detected by using a custom python code to draw a smoothed density plot to visualize the density of HiSeq reads in a given XY space of each tile. Digital gene expression (DGE) matrices are generate using STAR/STARsolo 2.7.5c with Gene,GeneFull, Velocyto, and polyAtrimming options. Data binning is performed by dividing the imaging space into 100 μm2 square grid with 10 μm simple side or 25 μm2 square grid with 5 μm side and collapsing all HDMI-UMI information into one barcode. Binned DGE matrix was analyzed in the Seurat v4 package for clustering analysis.

Transglutaminase 2 regulates terminal erythroid differentiation via cross-linking activity

Project description:To gain the whole picture of terminal erythroid differentiation, bone marrow erythroblasts of different maturation stages including proerythroblasts (Pro),basophilic erythroblasts (Baso), polychromatic erythroblasts (Poly) and orthochromatic erythroblasts (Ortho) were isolated and sorted.Transcriptomic analysis of these four stages of cells was performed.

Polyhexamethylene guanidine aerosol causes irreversible changes in blood proteins that associated with the severity of lung injury

Project description:Humidifier disinfectant (HD)-associated lung injury (HDLI) not only associates with increased acute morbidity and mortality, but also affects long term lung function due to lung fibrosis. However, there have been no validated marker capable of detecting exposure to HDs or severity of HDLI. This study aims to discover the differential abundant plasma proteome between them and develop prediction score platform using plasma proteome data from HD-exposed patients in order to classify the severity of HDLI. A total of 483 samples were used in this study. The samples used were 162 children in the normal group, 76 in the 4th stage, 51 in the 3rd stage, 54 in the 2nd stage, 42 in the 1st stage and 50 female adults in the normal group, 20 in the 4th stage, 7 in the 3rd stage, 6 in the 2nd stage, and 14 in 1st stage. The lower the grade, the greater the severity of HDLI.
