Project description:We found that iron chelation restored functional defects in aged HSC, including engraftment potential and platelet bias. To gain molecular insights into iron-dependent mechanism for sustaining HSC identity during aging, we performed Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) with lineage (Lin)− Sca-1+ cKit+ (LSK) cells isolated from aged mice after long-term regimens with iron chelator Deferoxamine or vehicle control.
Project description:We performed cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) of the LSK compartment of TdT-reporter and TdT-fate mapping mice, in order to elucidate the heterogeneity and developmental trajectories within the MPP (lymphoid-primed multipotent progenitor) and HSC (hematopoietic stem cell) compartments.
Project description:We treated lymphoblast cells with the iron chelator deferoxamine (DFO) for 60 hours to determine if iron chelation would affect the levels of intron lariats.
Project description:Using bulk RNA-seq, the transcriptional profile of two cell lines with high or low metastatic properties derived from single clones of the murine 4T1 cell line treated or untreated with iron chelator DFX was analyzed in order to determine the mechanism underlying the inhibition preference of DFX for highly metastatic 4T1 cells.
Project description:HeLa cells grown to subconfluent density and CaCo-2 cells grown to high density were either treated with an iron source (hemin) or an iron chelator (desferal). Cells were harvested and RNA was prepared by RNA-Clean (Hybaid-AGS) and the RNA was subjected to a subsequent clean up using the RNeasy (Qiagen) clean up procedure.
Project description:We report here the analysis of young and aged hematopoietic stem and progenitor cells (HSPCs) by transcriptional profiling (bulk RNA-Seq, CITE-Seq) and chromatin profiling (ATAC-Seq, scATAC-Seq). We use here a Clca3a1 as a surface marker to further fractionate HSPCs. HSPCs were sorted by flow cytometry. During the staining procedure for flow cytometry, the antibody cocktail also included antibodies labelled with oligos (antibody-derived tags =ADTs) which can later be analyzed by the 10x Chromium controller.

We use here a Clca3a1 as a surface marker to further fractionate HSPCs. HSPCs were sorted by flow cytometry. Where indicated, LT-HSCs were further fractionated into a Clca3a1 high or low population using a monoclonal antibody (10.1.1) purchased from the Developmental Studies Hybridoma Bank - DSHB. We report here the analysis of old LSK cells after Taz S89A overexpression. LSK cells were sorted by flow cytometry. The cells were infected in vitro with the indicated constructs and subjected to RNA-Seq analysis. We report here the analysis of BM-HPC#5 cells after PU1 knockdown. BM-HPC#5 cells with the indicated constructs were subjected to RNA-Seq analysis.
