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)
This study was aimed to investigate the effects of peripheral blood Th17 cells and their secreting IL-17, IL-21 in the occurrence and development of multiple myeloma (MM). A total of 55 patients with MM were divided into non-remission group (group A , n = 30), remission group (group B, n = 25); healthy volunteers were used as control group (group C , n =(More)
Abnormal immunophenotypes of hematopoietic cells can be detected by flow cytometry (FCM) to assist the diagnosis of myelodysplastic syndromes (MDS). We previously established a FCM scoring system for the diagnosis of low-grade MDS. In this study, additional valuable antigens were involved in an updated FCM scoring system (u-FCMSS) for all MDS subtypes. The(More)
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)
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)
Decitabine treatment improves immunological recognition that increases expression of cancer-testis antigens (CTAs) against solid tumors. The mechanisms of decitabine enhancement of immunogenicity when used for patients with myelodysplastic syndromes (MDS) remain unclear. In the present study, we found relatively low baseline expression of MAGE-A1, MAGE-A3,(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)
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)
