HLA-identical bone marrow transplantation (BMT) is associated with both graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) reactivity. Different T-cell subsets from the bone marrow (BM) graft may be responsible for GVHD and GVL reactivity after BMT. In the etiology of GVHD, not only CD8+ but also CD4+ donor T lymphocytes may play an important role. Here we report a patient with ch...
The small molecule inhibitor of the MDM2/p53 interaction Nutlin-3 significantly up-regulated the steady-state mRNA and protein levels of Notch1 in TP53(wild-type) (OCI, SKW6.4) but not in TP53(deleted) (HL-60) or TP53(mutated) (BJAB) leukemic cell lines. A direct demonstration that NOTCH1 was a transcriptional target of p53 in leukemic cells was obtained in experiments carried out with siRNA fo...
OBJECTIVE The aim of this study was to investigate the anti-leukemic activity of the Bruton tyrosine kinase inhibitor Ibrutinib in combination with the small molecule MDM-2 inhibitor Nutlin-3 in preclinical models. METHODS The potential efficacy of the Ibrutinib/Nutlin-3 combination was evaluated in vitro in a panel of B leukemic cell lines (EHEB, JVM-2, JVM-3, MEC-1, MEC-2) and in primary B-...
The aimed of this study was to evaluate curcumin as anticancer agent. The apoptogenic and Cytotoxic activity of curcumin were investigated against two human leukemic cell lines-U937 and Molt4. Cytotoxic activity was performed by using [3-[4, 5-dimethylthiazol-2yl] 2, 5 diphenyltetrazolium bromide] MTT assay. Also 4, 6-diamidino-2-phenylindole di-hydrochloride [DAPI] staining was used as a DNA-b...
Anti-thymocyte globulin (ATG), a horse antiserum to human thymus tissue, has been shown to induce granulocytic differentiation of the HL-60 human leukemia cell line. In this paper we describe the effect of ATG on leukemic blasts and its effect on other human leukemia cell lines in vitro. The in vitro differentiation effect of ATG was observed in blasts from two patients with leukemia and the hu...
The anti-leukemic activity of the mitochondria-targeting small molecule sodium dichloroacetate (DCA), used alone and in association with the small molecule inhibitor of the p53/MDM2 interaction Nutlin-3, was analyzed in primary B-chronic lymphocytic leukemia (B-CLL) samples (n=22), normal peripheral blood cells (n=10) and in p53wild-type EHEB, JVM-2, JVM-3 B lymphoblastoid cell lines. DCA exhib...
Anti-thymocyte globulin (ATG), a horse antiserum to human thymus tissue, has been shown to induce granulocytic differentiation of the III60 human leukemia cell line. In this paper we describe the effect of ATG on leukemic blasts and its effect on other human leukemia cell lines in vitro. The in vitro differentiation effect of ATG was observed in blasts from two patients with leukemia and the hu...
Detectable differences in surface membrane characteristics of normal lymphocyte populations have facilitated the classification of leukemic cells according to cell origin and Stage of differentiation. Recent reports show that distinct leukemic cell populations do not only express markers found on normal cell populations. Using specific antisera new antigenic determinants on cells of common acut...
High expression of the chemokine receptor 4, CXCR4, associated with a negative prognosis in acute myeloid leukemia, is related to hypoxia. Because CXCR4 expression is under the post-transcriptional control of microRNA-146a in normal and leukemic monocytic cells, we first investigated the impact of hypoxia on microRNA-146a and CXCR4 expression during monocytopoiesis and in acute monocytic leukem...
