BACKGROUND
Aberrant expression of the RON receptor tyrosine kinase is associated with tumor progression and carcinogenesis. The aims of this study were to determine the role and functional mechanisms of RON in Burkitt lymphoma (BL) and to document its potential as a therapeutic target.
METHODS
RON
Signals transduced through CD40 rescue cells of the Ramos-Burkitt lymphoma (Ramos-BL) B cell line from surface immunoglobulin M (sIgM)-triggered growth arrest and apoptosis. This study investigates whether protein tyrosine kinase (PTK) activity and tyrosine phosphorylation on p95(vav) and on the p85
Despite the recent advances in knowledge of the molecular mechanism by which interleukin-4 (IL-4) induces IgE production, little is known about the signal transduction pathway that leads to this event. This study investigated the signal transduction mechanism responsible for IL-4-induced expression
Pediatric and adult patients with recurrent/refractory Burkitt lymphoma (BL) continue to have poor outcomes, emphasizing the need for newer therapeutic agents. Bruton's tyrosine kinase (BTK) is activated following B-cell receptor stimulation and in part regulates normal B-cell development.
Burkitt lymphoma (BL) is an aggressive neoplasm characterized by consistent morphology and phenotype, typical clinical behavior and distinctive molecular profile. The latter is mostly driven by the MYC over-expression associated with the characteristic translocation (8;14) (q24; q32) or with variant
Selective serotonin reuptake inhibitors (SSRIs) are the treatment of choice for clinical depression and a range of anxiety-related disorders. They are well tolerated over extended periods with more than 50 million people worldwide benefiting from their use. Here we show that 3 structurally distinct
Burkitt lymphoma (BL) is the most common histological subtype of non-Hodgkin lymphoma (NHL) in children and adolescents. Through the introduction of short intensive multi-agent chemoimmunotherapy, survival has improved significantly over the past 30 years. However, this successful approach is
Epstein-Barr virus (EBV) persists as a life-long latent infection within memory B cells, but how EBV may circumvent the innate immune response within this virus reservoir is unclear. Recent studies suggest that the latency-associated non-coding RNAs of EBV may actually induce type I (antiviral)
Burkitt lymphoma (BL) is an aggressive B-cell neoplasm that is currently treated by intensive chemotherapy in combination with anti-CD20 antibodies. Because of their toxicity, current treatment regimens are often not suitable for elderly patients or for patients in developing countries where BL is
PI 3-kinase, an enzyme responsible for the phosphorylation of the D3 position of the inositol ring of phosphatidylinositol (PI), is recognized to be involved in the regulation of many cellular processes such as mitogenic signalling, inhibition of apoptosis, intracellular vesicle
Burkitt lymphoma cells and their counterpart of normal origin contain proteins with associated tyrosine protein, kinase activity. These proteins were isolated by affinity chromatography and Fast Pressure Liquid Chromatography. Proteins with enzyme activity had an app. M. W. of 47 KDa. This protein
The tie gene encodes a receptor tyrosine kinase that together with its thus far unidentified ligand appears to play a distinct role in the regulatory pathway of early hematopoiesis and angiogenesis. Here, we attempted to define the possible involvement of tie in the pathobiology of hematopoietic
CDC25B2, a protein tyrosine phosphatase closely related to the putative CDC25B oncogene, was identified in a Burkitt lymphoma cDNA library. CDC25B2 differs from CDC25B by a 14 residue insertion and a 41 residue deletion, which are both located in the amino-terminal region of the protein, upstream of
Stimulation of B cells by clustering their surface immunoglobulins (sIg) leads to enhanced phosphorylation of several cellular proteins on Ser and Tyr residues. The type II Fc gamma receptor (Fc gamma RII) is one of those proteins that undergo Ser phosphorylation. Upon affinity isolation of the Fc
The aim of the present study was to investigate the role and molecular mechanism of human IgD (hIgD) on the proliferation of human Burkitt lymphoma Daudi cells in vitro. Logarithmically growing Daudi cells were treated with hIgD for different time periods, and cell proliferation was evaluated by
