TMPRSS2-ERG junction oncogene is present in more than 50% of patients with prostate cancer and its expression is frequently associated with poor prognosis. Our aim is to achieve gene knockdown by siRNA TMPRSS2-ERG and then to assess the biological consequences of this inhibition. First, we designed siRNAs against the two TMPRSS2-ERG fusion variants (III and IV), most frequently identified in pa...

Downloa RSS2-ERG and other gene fusions involving ETS factors and genes with strong promoter elements are on in prostate cancer. Although ERG activation has been linked to invasive properties of prostate canhe precise mechanisms and pathways of ERG-mediated oncogenesis remain poorly understood. Here, we that ERG knockdown in VCaP prostate cancer cells causes an activation of cell adhesion, resu...

Purpose: To assess differentially methylated "landscapes" according to prostate cancer Gleason score (GS) andERGoncogene expression status, and to determine the extent of polycomb group (PcG) target gene involvement, we sought to assess the genome-wideDNAmethylation profile of prostate cancer according to Gleason score and ERG expression. Experimental Design:Genomic DNA from 39 prostate cancer ...

Recurrent gene fusions involving ETS family genes are a distinguishing feature of human prostate cancers, with TMPRSS2-ERG fusions representing the most common subtype. The TMPRSS2-ERG fusion transcript and its splice variants are well characterized in prostate cancers; however, not much is known about the levels and regulation of wild-type ERG. By employing an integrative approach, we show tha...

ERG is a member of the ETS transcription factor family that is highly enriched in endothelial cells (ECs). To further define the role of ERG in regulating EC function, we evaluated the effect of ERG knock-down on EC lumen formation in 3D collagen matrices. Blockade of ERG using siRNA completely interferes with EC lumen formation. Quantitative PCR (QPCR) was used to identify potential downstream...

half of all prostate cancers in the Western countries harbor gene fusions that involve regulatory sequences of the androgen receptor (AR)-responsive genes (predominantly TMPRSS2) and protein coding sequences of nuclear transcription factors of the ETS gene family (predominantly ERG). This leads to unscheduled androgen-dependent expression ofETS-related transcription factors in tumor cell-specif...

ERG (ETS-related gene) belongs to the ETS family of transcription factors, and has been recently reported to contribute to homeostatic balance in skeleton cell plasticity. MicroRNA-30 (miR-30) family is also demonstrated to play a role in controlling chondrocyte differentiation. The current study investigated the miR-30b and ERG expression in articular cartilage of osteoarthritis (OA) patients....

Over the last few years, the ETS transcription factor ERG has emerged as a major regulator of endothelial function. Multiple studies have shown that ERG plays a crucial role in promoting angiogenesis and vascular stability during development and after birth. In the mature vasculature ERG also functions to maintain endothelial homeostasis, by transactivating genes involved in key endothelial fun...

OBJECTIVE To compare ERG expression and gene rearrangements rates in metastatic and castration-resistant prostate cancer (CRPC) to localized disease as ERG is the most common genetic event in early prostate cancer (PCa) with potential prognostic and therapeutic implications. METHODS We evaluated ERG protein expression in 344 patients with PCa in 3 cohorts including localized, metastatic, and ...

BACKGROUND The E-26 transformation-specific related gene (ERG) is frequently expressed in cytogenetically normal acute myeloid leukemia (CN-AML). Herein, we performed a meta-analysis to investigate the relationship between the prognostic significance of ERG expression and CN-AML. METHODS A systematic review of PubMed database and other search engines were used to identify the studies between ...
