Frostegård et al. (J Lipid Res 1990;31:37-44) demonstrated that the proliferation of the human monocyte cell line U937 is critically dependent on the uptake of low-density lipoprotein (LDL) via the apo B, E (LDL) receptor, a characteristic that was used to detect patients with familial defective apolipoprotein B-100 (FDB). Here we applied this principle to develop a simple and reproducible assa...
In this report we discuss the role of interferon regulatory factor 1 (IRF-1) in the regulation of ornithine decarboxylase (ODC) transcription during IFN gamma human macrophage activation. We show that a binding sequence for the transcription factor IRF-1 is contained in the first intron of the human ODC gene (from nt +2711 to nt +2722) and we demonstrate that the level of expression of IRF-1 in...
BACKGROUND The transcription factor Ecotropic Virus Integration site 1 (EVI1) regulates cellular proliferation, differentiation, and apoptosis, and its overexpression contributes to an aggressive course of disease in myeloid leukemias and other malignancies. Notwithstanding, knowledge about the target genes mediating its biological and pathological functions remains limited. We therefore aimed ...
The nuclear factor I (NFI) family of transcription/replication proteins is required for the cell type-specific expression of a number of cellular and viral genes. There are four evolutionarily conserved NFI genes (NFI-A, -B, -C and -X) that encode DNA-binding proteins of similar or identical DNA-binding specificity. To address the role of this family of highly conserved transcription/replicatio...
We have analyzed the organization and expression of the immunoglobulin heavy and light chain gene in the human myeloblastic leukemic sublines, ML1, ML2, and ML3, and in the human myeloid leukemic cell lines, HL-60, U937, THP1, and K562. ML1, ML2, and ML3 cells, despite a predominant granulocytic phenotype, express a rearrangement of the immunoglobulin heavy chain gene that typically occurs duri...
OBJECTIVES Angiogenesis, the process of formation of new blood vessels, is essential for development of solid tumors. At first, it was first assumed that angiogenesis is not implicated in the development of acute myeloid leukemia (AML) as a liquid tumor. One of the most important elements in bone marrow microenvironment is mesenchymal stem cells (MSCs). These cells possess an intrinsic tropism ...
background: leukemia is a malignant proliferative disorder of the hematopoietic cells. the important role of angiogenesis in leukemia has been reported by several studies. matrix metalloproteinases (mmps) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. objective: the present study was conducted to evaluate the patterns of ...
