The production, survival, and function of monocytes and macrophages is regulated by the macrophage colony-stimulating factor (M-CSF or CSF-1) through its tyrosine kinase receptor Fms. Binding of M-CSF to Fms induces the tyrosine phosphorylation and association of a 150-kD protein with the phosphotyrosine-binding (PTB) domain of Shc. We have cloned p150(More)
To elucidate the relationship between malignant transformation and cytokine receptor expression, the interleukin-3 receptor (IL-3R) complex was examined in an IL-3-dependent parental line and cells transformed by cytokines and oncogenes. In IL-3-dependent cells grown in medium containing optimum amounts of IL-3, the IL-3R complex was detected at low levels(More)
Tetraspanins are commonly believed to act only as "molecular facilitators," with no direct role in signal transduction. We herein demonstrate that upon ligation, CD37, a tetraspanin molecule expressed on mature normal and transformed B cells, becomes tyrosine phosphorylated, associates with proximal signaling molecules, and initiates a cascade of events(More)
The normal proto-oncogene c-fms encodes the macrophage growth factor (M-CSF) receptor involved in growth, survival, and differentiation along the monocyte-macrophage lineage of hematopoietic cell development. A major portion of our research concerns unraveling the temporal, molecular, and structural features that determine and regulate these events.(More)
Although insulin-like growth factor (IGF-1) stimulated 3H-thymidine incorporation upon addition to the interleukin-3 (IL-3)-dependent cell line FDC-P1, IGF-1 did not relieve IL-3 dependency for growth. To further examine the effects of IGF-1 on hematopoietic cells, FDC-P1 cells were infected with a retroviral construct (LISN) containing the human IGF-1(More)
Alpha-methylacyl CoA racemase (AMACR), also known as P504S, plays an important role in peroxisomal beta-oxidation of branched-chain fatty acids. It has recently been shown that AMACR is highly expressed in prostate cancer and that it may be an important diagnostic marker for prostate carcinoma. However, little is known about expression of AMACR in normal(More)
Over the past decade, there has been an exponential increase in our knowledge of how cytokines regulate signal transduction, cell cycle progression, differentiation and apoptosis. Research has focused on different biochemical and genetic aspects of these processes. Initially, cytokines were identified by clonogenic assays and purified by biochemical(More)
The macrophage colony-stimulating factor receptor and several other hematopoietic growth factor receptors induce the tyrosine phosphorylation of a 145- to 150-kD protein in murine cells. We have previously cloned a cDNA for the murine 150-kD protein, SHIP, and found that it encodes a unique signaling intermediate that binds the SHC PTB domain through at(More)
Epidemiological studies have shown that consumption of red meat increases the risk of developing colon cancer. An enzyme, alpha-methylacyl CoA racemase (AMACR), also known as P504S, plays an important role in peroxisomal beta-oxidation of branched-chain fatty acids from red meat and dairy products. High expression of AMACR was recently found in prostate(More)
TRU-016 is a SMIP(TM) (monospecific protein therapeutic) molecule against the tetraspanin transmembrane family protein CD37 that is currently in Phase 2 trials in Chronic Lymphocytic Leukemia (CLL) and Non-Hodgkin Lymphoma (NHL). In an attempt to enhance the ADCC function of SMIP-016, the chimeric version of TRU-016, SMIP-016(GV) was engineered with a(More)
