The ETS transcription factor ERG plays a central role in definitive hematopoiesis, and its overexpression in acute myeloid leukemia (AML) is associated with a stem cell signature and poor prognosis. Yet how ERG causes leukemia is unclear. Here we show that pan-hematopoietic ERG expression induces an early progenitor myeloid leukemia in transgenic mice. Integrated genome-scale analysis of gene e...

The translocation liposarcoma (TLS) gene is fused to the ETS-related gene (ERG) in human myeloid leukemia, resulting in the generation of a TLS-ERG protein. We demonstrate that both TLS and the TLS-ERG leukemia fusion protein bind to RNA polymerase II through the TLS N-terminal domain, which is retained in the fusion protein; however, TLS recruits members of the serine-arginine (SR) family of s...

Recently, gene fusions between the androgen responsive gene TMPRSS2 and members of the ETS-family of DNA-binding transcription factor genes were found in prostate cancer. Recurrent fusions were identified between the 5'-noncoding region of TMPRSS2 and ERG, or less frequently ETV1 or ETV4, resulting in overexpression of normal or truncated ETS-proteins. Herein, we have analyzed a series of 50 pr...

TGF-β/Smads signaling plays a significant role in the regulation of growth of normal and prostate cancer cells. Smad proteins function as important mediators of intracellular signal transduction of transforming growth factor-β (TGF-β). TGF-β signaling pathway is known to regulate cell proliferation, differentiation, apoptosis and play a major role in some human diseases and cancers. Following t...

The Ets-related gene (ERG) is an Ets-transcription factor required for normal blood stem cell development. ERG expression is down-regulated during early T-lymphopoiesis but maintained in T-acute lymphoblastic leukemia (T-ALL), where it is recognized as an independent risk factor for adverse outcome. However, it is unclear whether ERG is directly involved in the pathogenesis of T-ALL and how its...

Purpose: Fusion of the TMPRSS2 gene with the ERG oncogene and aberrant DNAmethylation patterns are commonly found in prostate cancer. The aim of this study was to analyze the relationship between ERG expression, DNA methylation of three biomarkers, and clinicopathologic features of prostate cancer. Experimental Design: Immunohistochemistry for ERG protein was conducted as a surrogate for TMPRSS...

Oncogenic activation of the ETS Related Gene (ERG) in humans was originally identified insubsets of Ewing sarcomas, myeloid leukemias and, recently, in the majority of prostatecancers. Expression of human ERG protein and consequently its functions in normal anddisease states needs to be better understood in light of its suggested role in cell differentiationand proliferation. He...

Aneuploidy is one of the hallmarks of cancer. Acquired additions of chromosome 21 are a common finding in leukemias, suggesting a contributory role to leukemogenesis. About 10% of patients with a germ line trisomy 21 (Down syndrome) are born with transient megakaryoblastic leukemia. We and others have shown acquired mutations in the X chromosome gene GATA1 in all these cases. The gene or genes ...

AIM Prostate cancer (PCa) is the second most common cancers in men worldwide. Its incidence can be influenced by several risk factors including genetic susceptibility. Therefore the search for the expression of a certain gene (ERG) and its rearrangement could give us clues for proper identification of PCa. And the study of ERG expression and its comparison to FISH in Egyptian patients can show ...
