The TEL/PDGFbetaR gene, which encodes a fusion protein containing the ETS-family member TEL fused to the protein-tyrosine kinase domain of the platelet-derived growth factor receptor-beta (PDGFbetaR), confers interleukin 3 (IL-3)-independent growth on Ba/F3 hematopoietic cells. TEL/PDGFbetaR mutants have been generated that contain tyrosine-to-phenylalanine (Tyr-->Phe) substitutions at phosphor...

Recent excavations at Tel Gezer have systematically revealed a broad exposure west of the Iron Age gate complex (popularly referred to as “Solomonic Gate”). This report focuses on occupation layers 10th century BCE (our Strata 8 and 7, dated by 14C ceramic analyses). Stratum represents unique period Gezer’s history when city experienced major shift in urban planning, evidenced monumental admini...

The TEL gene on 12p12-13 is a target for a number of translocations associated with various hematological malignancies. The fusion of the TEL gene to the Syk gene in a patient with myelodysplastic syndrome (MDS) with t(9;12)(q22;p12) is reported. Southern blot analysis of patient bone marrow cells with TEL and Syk gene probes detected rearranged fragments. Anchored polymerase chain reaction ide...

The chromosomal translocation t(12; 22)(p13;q11) in human myeloid leukemia generates an MN1-TEL (meningioma 1-translocation-ETS-leukemia) fusion oncoprotein. This protein consists of N-terminal MN1 sequences, a transcriptional coactivator fused to C-terminal TEL sequences, an ETS (E26 transformation-specific) transcription factor. Enforced expression of MN1-TEL in multipotent hematopoietic prog...

TEL-AML1 is expressed from the t(12;21) chromosomal translocation inB-precursor acute lymphocytic leukemia (ALL). Creation of the TEL-AML1fusion disrupts one copy of the TEL and AML1 genes, and loss of TEL or AML1 is also associated with cases of acute leukemia without TEL-AML1. To determine whether TEL-AML1 can contribute to leukemogenesis, we transduced marrow from C57BL/6 mice with a retrovi...
