Lectins (carbohydrate-binding proteins) are able to distinguish different patterns of glycosylation on cell surfaces. This study investigated the effects lectins from Alpinia purpurata inflorescence (ApuL) and Schinus terebinthifolia leaf (SteLL) viability human leukemia cells (K562, chronic myeloid leukemia; JURKAT, acute lymphoblastic leukemia) mesenchymal stem (MSCs) umbilical cords. In addi...

BACKGROUND CD33 is a well-known stem cell target in acute myeloid leukemia. So far, however, little is known about expression of CD33 on leukemic stem cells in chronic leukemias. DESIGN AND METHODS We analyzed expression of CD33 in leukemic progenitors in chronic myeloid leukemia by multi-color flow cytometry and quantitative polymerase chain reaction. In addition, the effects of a CD33-targe...

synthesis, characterization, spectral and theoretical calculations of sodium tetrafluoroborate (iii) (stfb) has been studied in this research. sodium tetrafluoroborate (iii) was synthesized by a sonochemical method and characterized by ir, uv/vis, 11b-nmr and mass spectrometer techniques. the nano compound was characterized by scanning electron microscopy (sem), x-ray powder diffraction (xrd) a...

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clin...

Imatinib is actively transported by organic cation transporter-1 (OCT-1) influx transporter, and low OCT-1 activity in diagnostic chronic myeloid leukemia blood mononuclear cells is significantly associated with poor molecular response to imatinib. Herein we report that, in diagnostic chronic myeloid leukemia mononuclear cells and BCR-ABL1+ cell lines, peroxisome proliferator-activated receptor...

Leukemia is thought to arise from malignant stem cells, which have been described for acute and chronic myeloid leukemia (AML and CML) and for acute lymphoblastic leukemia (ALL). Leukemia stem cells (LSCs) are relatively resistant to current chemotherapy and likely contribute to disease relapse and progression. Consequently, the identification of drugs that can efficiently eradicate LSCs is an ...

ALOX5 is implicated in chronic myeloid leukemia development in mouse leukemic stem cells, but its importance in human chronic myeloid leukemia is unknown. Functional ALOX5 was assessed using an LTB4 ELISA and ALOX5, and LTB4R1 mRNA expression was determined via a TaqMan gene expression assay. LTB4R1 and 5-LOX protein levels were assessed by cell surface flow cytometry analysis. At diagnosis ALO...

Chronic myeloid leukemia (CML) is a malignant myeloproliferative disorder originating from a pluripotent hematopoietic stem cell that acquires a Philadelphia (Ph) chromosome encoding the BCR-ABL oncogenic fusion protein. This molecular abnormality that is thought to be causative in CML was the first acquired chromosome translocation associated with a human malignancy. This chromosomal transloca...
