MicroRNAs (miRNAs) are key regulators of hematopoietic cell differentiation and may contribute to altered growth of leukemic stem cells. Using microarray-based miRNA profiling, we found that miRNA 486 (miR-486) is significantly upregulated in chronic myeloid leukemia (CML) compared with normal CD34(+) cells, particularly in the megakaryocyte-erythroid progenitor population. miR-486-5p expressio...
Suppressor of cytokine signaling 3 (SOCS3) plays an important role in mice fetal liver erythropoiesis, but the roles of SOCS3 in human hematopoietic stem cells (HSCs) have not been well investigated. In the present study, lentiviral small interference RNA expression vectors (shRNA) of SOCS3 were constructed and stably transferred into HSCs. We found that SOCS3 knockdown induced erythroid expans...
BACKGROUND/AIM β-Thalassemia/hemoglobin E (β-thal/HbE) is a common hereditary anemia in Thailand. Ineffective erythropoiesis due to apoptosis and decreased lifespan of circulating thalassemic red blood cells are the major causes of anemia. Changes to bone marrow microenvironment could contribute to apoptotic events. This study examined the effects of cytokines interleukin-1β, tumor necrosis fac...
BACKGROUND Sickle cell disease (SCD) is a disorder of red blood cells (RBCs) expressing abnormal hemoglobin-S (HbS) due to genetic inheritance of homologous HbS gene. However, people with the sickle cell trait (SCT) carry a single allele of HbS and do not usually suffer from SCD symptoms, thus providing a rationale to treat SCD. METHODS To validate gene therapy potential, hematopoietic stem c...

B19 human parvovirus is the etiologic agent of transient aplastic crisis. To better understand B19 virus-induced hematopoietic suppression, we studied the host cell range of the virus using in vitro bone marrow cultures. First, B19 virus replication was examined in the presence of various purified cytokines using DNA dot blot analysis. Replication was detected only in erythropoietin-containing ...
Although erythropoietin (Epo) is essential for the production of mature red blood cells, the cooperation with other factors is required for a proper balance between progenitor proliferation and differentiation. In avian erythroid progenitors, steroid hormones cooperate with tyrosine kinase receptors to induce renewal of erythroid progenitors. We examined the role of corticosteroids in the in vi...
