This study was aimed to investigate the cytogenetic characteristics of hematopoietic cells (HC) and bone marrow mesenchymal stoma cells (BMMSC) isolated from patients with myelodysplastic syndrome (MDS) and healthy individuals as normal controls, and to clarify whether HC and BMMSC are simultaneously involved and participate in pathogenesis and development(More)
AIM This study compared genetic aberrations in hematopoietic cells (HCs) and mesenchymal stem cells of myelodysplastic syndrome (MDS-MSCs) patients. METHODS We obtained chromosomes with aberrations from 22 patients with MDS and chromosomes from 7 healthy individuals. Chromosomal aberrations in both HCs and MSCs were identified using G-banding. We then(More)
The progressive mechanism underlying myelodysplastic syndrome remains unknown. Here we identify ROBO1 and ROBO2 as novel progression-related somatic mutations using whole-exome and targeted sequencing in 6 of 16 (37.5%) paired MDS patients with disease progression. Further deep sequencing detects 20 (10.4%) patients with ROBO mutations in a cohort of 193(More)
The international prognostic index (IPI) has been established as one of the best predictors of outcome, and several different immunologic subtypes have been established as independent predictors of diffuse large B-cell lymphoma (DLBCL). This study was aimed to reassess and re-evaluate the useful value of these prognostic predictors in patients treated with(More)
OBJECTIVE To investigate phenotype, cell differentiation and cytogenetic properties of bone marrow (BM) mesenchymal stem cells (MSC) separated from the myelodysplastic syndrome (MDS) patients. And to analyze cytogenetic aberration of MSC derived from MDS (MDS-MSC) and its mechanism in pathogenesis of MDS. METHODS Adherent MSC from both myelodysplastic (n(More)
Cerebral venous and sinus thrombosis is a rare cerebrovascular disorder, which seldom represents a complication of acute promyelocytic leukemia (APL). As a part of the coagulopathy of APL, thrombosis is a less recognized and underestimated life-threatening manifestation and is overshadowed by the more obvious bleeding complications. Here, we described a(More)
Novel sequencing designs are necessary to supplement the recognized knowledge of myelodysplastic syndrome (MDS)-related genomic alterations. In this study, we sequenced 28 target genes in 320 Chinese MDS patients but obtained 77.2% of recall factors and 82.8% of genetic abnormalities (including karyotype abnormalities). In addition to known relationships(More)
The study was aimed to investigate the biological behavior of stromal cell-derived factor-1 (SDF-1) in migration, adhesion and apoptosis as well as the related signaling transduction pathways in different kinds of acute myeloid leukemia (AML) cell lines. The expression of surface molecules on AML (KG1a, ML1 and U937) cells were analyzed by flow cytometry.(More)
