A key event in the response of cells to proliferative signals is the rapid, transient induction of the c-fos proto-oncogene, which is mediated through the serum response element (SRE) in the fos promoter. Genomic footprinting and transfection experiments suggest that this activation occurs through a ternary complex that includes the serum response factor(More)
The breast and ovarian cancer susceptibility gene BRCA1, is a nuclear phosphoprotein which functions as a tumor suppressor. To investigate the role of BRCA1 in apoptosis, we have developed mouse fibroblast cell lines and human breast cancer cell lines expressing BRCA1. The expression of BRCA1 protein in the BRCA1 transfectants were analysed by(More)
BRCA1 gene mutations are responsible for hereditary breast and ovarian cancers. In sporadic breast tumors, BRCA1 dysfunction or aberrant subcellular localization is thought to be common. BRCA1 is a nuclear-cytoplasm shuttling protein and the reason for cytoplasmic localization of BRCA1 in young breast cancer patients is not yet known. We have previously(More)
Cytogenetic analysis of Ewing's sarcoma, primitive neuroectodermal tumors and Askin tumors revealed characteristic translocations t(11;22) or t(21;22). Molecular analysis of these translocations revealed 5'-region of EWS gene (from band 22q12) is fused to the 3'-region of either Fli-1 gene (from band 11q24) or erg gene (from band 21q22). Functional(More)
EWS and TLS/FUS genes, which code for RNA binding proteins are involved in a wide variety of human solid tumors. The TLS/FUS gene is involved both in human myxoid liposarcomas which carry a characteristic chromosomal translocation, t(12;16)(q13;p11) and in human myeloid leukemias with recurrent chromosomal translocation, t(16;21)(p11:q22). The TLS/FUS gene(More)
We have isolated a cDNA clone representing the complete coding sequence of a human gene named erg, related to the ets oncogene. Nucleotide sequence analysis of this cDNA (4.6 kilobases long) revealed that this gene encodes a 363-residue protein whose predicted amino acid sequence showed a homology of approximately equal to 40% and approximately equal to 70%(More)
In the generation of the acutely transforming avian retrovirus E26, both myb and ets genes have been transduced, leading to the production of a Gag-Myb-Ets fusion protein. This co-occurrence of v-myb and v-ets oncogenes suggests that the two might have a functional relationship. To look for such a relationship, we tested the transcriptional activation(More)
Many chimeric oncogenes have been identified by virtue of the association between chromosomal translocation and specific human leukemias. However, the biological mechanism by which these oncogenes disrupt the developmental program of normal human hematopoietic cells during the initiation of the leukemogenic process is poorly understood due to the absence of(More)
An ETS family member, ETS Related Gene (ERG) is involved in the Ewing family of tumors as well as leukemias. Rearrangement of the ERG gene with the TMPRSS2 gene has been identified in the majority of prostate cancer patients. Additionally, overexpression of ERG is associated with unfavorable prognosis in prostate cancer patients similar to leukemia(More)
The avian acute leukemia virus E26 induces a mixed erythroid-myeloid leukemia in chickens and carries two distinct oncogenes, v-myb and v-ets. Recently, a novel gene named erg, closely related to the v-ets oncogene, was identified in human COLO 320 cells and the nucleotide sequence of its approximately 5.0-kilobase transcript, erg 1 was determined. In the(More)
