Analysis of bone marrow (BM) mesenchymal stromal cells from adult patients representing MDS subtypes RCMD (refractory cytopenia with multilineage dysplasia) and RAEB (refractory anemia with excess blasts). Results provide insight into molecular changes in the BM microenvironment contributing to MDS.

(Submitter supplied) Myelodysplastic syndrome (MDS) is a group of heterogeneous clonal stem cell disorders. We hypothesize that gene expression changes in the bone marrow (BM) microenvironment might play a fundamental role in the development and progression of MDS. The goal of the present study is to investigate the differences in gene expression profiles of BM mesenchymal stromal cells (MSCs) between MDS patients and normal individuals, as well as between MDS subtypes. more...

(Submitter supplied) Altered bone marrow hematopoiesis and immune suppression is a hallmark of myelodysplastic syndrome (MDS). While the bone marrow microenvironment influences malignant hematopoiesis, the mechanism leading to MDS-associated immune suppression is unknown. We tested whether mesenchymal stromal cells (MSCs) contribute to this process. Here, we developed a model to study cultured MSCs from MDS patients compared to similar aged matched normal controls for regulation of immune function. more...

(Submitter supplied) Myelodysplastic syndromes (MDS) are a group of clonal disorders of hematopoietic stem cells. Mesenchymal stem cells (MSC) are the progenitors of the Bone Marrow (BM) stroma and have been involved in the physiopathology of MDS. The presence of cytogenetic aberrations on MSC from MDS patients is controversial. The aim of the study is to characterize BM derived MSC from patients with MDS using: kinetic studies, immunophenotyping, fluorescent in situ hybridisation (FISH) analysis and genetic changes by array based comparative genomic hybridization (array-CGH). more...

(Submitter supplied) Mesenchymal stromal cells (MSC) are involved in the pathogenesis of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), but how they contribute to the expansion of malignant cells and hematopoietic failure is poorly understood. To further characterize the pathological phenotype we performed RNA sequencing of MSC from patients with MDS and AML. Data analysis revealed a specific molecular signature with a significant overlap of genes commonly deregulated in all MDS subtypes and in AML. more...

(Submitter supplied) Myelodysplastic syndromes(MDS) are a group of heterogeneous disease. Emerging evidence has shown the bone marrow(BM) endothelial progenitor cells(EPCs) are also heterogeneity. To uncover the underlying mechanism of heterogeneous BM EPCs in different types of MDS patients. RNA sequencing(RNA-seq) analyses were performed to analyse BM EPCs at day 7 in culture from lower-risk MDS(N=3), higher-risk MDS(N=3), acute myloid leukemia(AML) patients(N=3) and healthy donors(HDs)(N=3). more...

(Submitter supplied) Prior studies using DNA microarray platforms have shown alterations of gene expression profiles (GEPs) of marrow cells in myelodysplastic syndromes (MDS). Using the increased sensitivity and accuracy of high-throughput RNA sequencing (RNA-Seq) for detecting and quantifying mRNA transcripts, our study has demonstrated novel significant differences in GEPs between MDS and normal CD34+ marrow cells with 41 genes identified as disease classifiers. more...

(Submitter supplied) Myelodysplastic syndromes (MDS) are a heterogenous group of diseases affecting the hematopoietic stem cell that are curable only by stem cell transplantation. Both hematopoietic cell intrinsic changes and extrinsic signals from the bone marrow niche seem to ultimately lead to MDS. Animal models of MDS indicate that alterations in specific mesenchymal progenitor subsets in the bone marrow microenvironment can induce or select for abnormal hematopoietic cells. more...

(Submitter supplied) People with mitochondrial disease are susceptible to metabolic decompensation and neurological symptom progression in response to an infection. Increasing evidence suggests that mitochondrial dysfunction may cause chronic inflammation, which may promote hyperresponsiveness to pathogens and neurodegeneration. We collected whole blood and isolated peripheral blood mononuclear cells from mitochondrial disease patients and healthy controls and examined transcriptional changes to identify common gene signatures of immune dysfunction in mitochondrial disease. more...
