Iron chelation shifts endothelial phenotypes

ABSTRACT: Iron deficiency is a highly prevalent nutrient deficiency and the most common cause of anemia. Although iron deficiency exacerbates cardiovascular disease, the direct impact of iron deficiency on the vasculature remains unstudied. Human lymphatic and arterial endothelial cells were treated with deferoxamine for 24 hours to assess the impact of iron deficiency on endothelial cell phenotypes. We found iron chelation upregulated the expression of arterial makers in both cell types. In lymphatic endothelial cells, iron chelation decreased the expression of lymphatic markers. These data suggest iron chelation shifts endothelial cells toward an arterial phenotype.

Treatment of a human lymphoblastoid cell line with the iron chelator deferoxamine

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.

Change expression of genes in iron chelation and deficient conditions

Project description:Firstly, cell senescence and anti-oxidant genes were down-regulated by iron deficient mice and iron-specific chelator deferoxamine (DFO) using a DNA microarray. Our data suggested that down-regulation of anti-oxidant genes and cell senescence gene induced oxidative stress in iron-deficient and -specific chelated condition.

CITE-seq of LSK cells from aged mice after long-term iron chelator regimen

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.

Iron chelation therapy elicits innate immune control of metastatic ovarian cancer

Project description:Iron accumulation in cancer cells contributes to malignant progression and chemoresistance. While disrupting this process can influence various hallmarks of cancer, the immunomodulatory effects of chelating iron in tumors remain undefined. Here, we report that treatment with deferiprone, an FDA-approved iron chelator, elicits innate immune responses that control metastatic ovarian cancer. Deferiprone reprogrammed ovarian cancer cells towards an immunostimulatory state characterized by enhanced production of type I interferon (IFN) and surface overexpression of molecules that activate natural killer (NK) cells. Mechanistically, this reprogramming was driven by innate sensing of mitochondrial DNA in the cytosol and concomitant activation of nuclear DNA damage responses evoked upon iron chelation. Deferiprone administration synergized with chemotherapy and prolonged the survival of mice bearing metastatic ovarian cancer by bolstering intratumoral NK cell infiltration and type I IFN responses. Iron chelation may represent an alternative immunotherapeutic approach for malignancies that are normally refractory to T cell-centric modalities.

Transcription profiling of H. pylori stationary (Stat Chelate and Stat.iron.survival)and exponential (Log Chelate and Log.iron.survival) subjected to chelation using DPP

Project description:This data set was used to determine genes that are regulated by iron availability and to access the growth phase dependence on that regulation. Stationary (Stat Chelate and Stat.iron.survival)and exponential (Log Chelate and Log.iron.survival)were subjected to chelation using DPP. Growth status of the cultures was confirmed by determing the correlation coefficient of the Stat chelate T=0/control and Log Chelate T=0/control vs data generated in the TC Motility series. Arrays used for iron addback experiments are listed as FeAddBack-1-time or FeAddBack-2-time.

Proteomic analyses of iron deprived NK92 cells with deferoxamine or PPMX-T003

Project description:This work aims to detect the differentially expressed proteins between transferrin receptor 1 inhibition and iron chelation in a natural killer cell lymphoma-derived cell line NK92. Cells were treated with 500 μM deferoxamine or 10 μg/mL PPMX-T003 (an anti-transferrin receptor 1 inhibitory antibody) for 24 hours and lysed with RIPA buffer supplied with a proteasome inhibitor cocktail and a phosphatase inhibitor.

Expression changes in the XY fetal gonads due to iron deficiency

Project description:Iron plays an important role in epigenome regulation by acting as a cofactor.We developed a method to enrich pre-Sertoli (Nr5a1 positive(+)) cells from mouse embryonic gonads carrying Nr5a1-hCD271 transgene. To examine mRNA expression in pre-Sertoli cells treated with the iron chelator Deferoxamine (Dfo), pre-Sertoli cells were purified and introduced into RNA seq analyses. As a result, we found that the expression of many genes, including Sry, changes due to iron deficiency.

Iron Chelators Treatment on MCF-7 Human Breast Cancer Cell

Project description:Iron-deficiency affects 500 million people, yet the molecular role of iron in gene expression remains poorly characterized. Moreover, the alterations in global gene expression after iron chelation remains unclear and are important to assess for understanding the molecular pathology of iron-deficiency and the biological effects of iron chelators. We assessed the effect on whole genome gene expression of two iron chelators (desferrioxamine and 2-hydroxy-1-napthylaldehyde isonicotinoyl hydrazone) that have markedly different permeability properties. Sixteen genes were significantly regulated by both chelators, while a further 50 genes were regulated by either ligand. Most of the genes identified in this study have not been previously described to be iron-regulated and are important for understanding the molecular and cellular effects of iron-deficiency.
