Loss of ERG recruits the AR to the promoter of c-MYC, blocking its transcriptional activation.116, 117 Conversely, androgen deprivation in prostate cells can result in a cooperative interaction between ERG and the transforming growth factor /bone morphogenic pathway; the latter is an initiator of EMT closely linked to WNT signalling.99 The cooperation is mainly achieved through interactions with transforming growth factor and SMAD3 to control mesenchymal differentiation.39 Inhibition of AR-regulated gene transcription is further enhanced by ERG at the epigenetic level when HDAC13 and the H3K27 methyltransferase EZH2 are recruited to AR/ERG-binding sites.

Sperone A, Dryden N, Birdsey G, Madden LE, Evans P, Mason JC et al. After 4 weeks of treatment tumour growth inhibition, reduced tumour weight and increased cell death was observed with minimal toxicity.204 This approach could be used in the future to personalise treatment by targeting specific oncogenic fusions within a tumour. We further conducted a systematic review and meta-analysis of TMPRSS2:ERG fusions in relation to race, Gleason score, and tumor stage, combining results from Ghana with 40 additional studies. Tsuzuki S, Taguchi O, Seto M . Nucleic Acids Res 2013; 41: 125138. The genomic complexity of primary human prostate cancer. Mice that overexpress the 81 isoform die at birth from respiratory failure are smaller and their skeletons hypo-mineralised.90 In cell lines, the expression of ERG isoforms that include exon 7b results in increased proliferation and invasion of prostate cancer cells;81 and both exon 7 and exon 7b inclusion increases in advanced prostate cancer (pathological stage T3).41 As exons 7 and 7b encode part of the TAD (Figure 1), alternative splicing therefore is likely to modulate ERGs effect on the transcription of target genes.60, Over the last decade, ERG has been increasingly implicated in the aetiology of prostate cancer.

The 100% concordance in ERG gene status of CRPC (tumor biopsies and CTCs) and therapy-naive tissues acquired several years and treatments previously suggests that, despite multiple foci of cancer with different ERG gene status existing in a single prostate , the cancer that is most commonly detected on trans-rectal biopsy of the prostate will . Donaldson LW, Petersen JM, Graves BJ, McIntosh LP . Influenza and SARS-coronavirus activating proteases TMPRSS2 and HAT are expressed at multiple sites in human respiratory and gastrointestinal tracts.

Nature 2012; 487: 239243. 2014 Jan 20;32(3):206-11 J. Treatment with the PARP inhibitor olaparib significantly reduced the invasive abilities of ERG+ cells.156 Exposure of ERG+ /PTEN prostate cells to the PARP inhibitor rucaparib was shown to sensitise the cells to low-dose radiation. This suggests that ERG promotes the de-differentiaton of prostate epithelium.104 ERG may also have a role in cell lineage selection as its overexpression causes stem cell surface markers (such as CD49F) normally expressed by the basolateral layer of the prostate to be expressed in luminal cells.97 It is the basal cell layer and stem cells of the prostate that show the biggest response to ERG overexpression resulting in ductal dysplasia and PIN lesions.110, 111, The use of chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq) has revealed a complex network of transcriptional cross-talk between ERG, the androgen receptor (AR) and epigenetic programming in the context of prostate cancer. Half of all prostate cancers are caused by the TMPRSS2-ERG gene-fusion, which enables androgens to drive expression of the normally silent E26 transformation-specific (ETS) transcription factor .

Overwhelming evidence suggests that ERG does contribute to worse outcomes and is involved in the regulation of signalling pathways that are dysregulated. A random seven amino acid phage display library (1) was pre-adsorbed onto purified GUS control protein (2) to remove non-specific peptides, pre-cleared phage peptides were then enriched for ERG-binding peptides by employing purified recombinant ERG protein as bait (3), bound phage clones were then eluted (4) and propagated (5).

AR signalling is crucial for the lineage-specific differentiation of prostate epithelia; ERG is able to disrupt differentiation and maintain cells in a de-differentiated state.104 ERG can achieve this disruption via several mechanisms: through physical interaction with the AR protein, through binding to the promoter of AR itself and by binding to the promoters of downstream, AR-regulated genes.112 AR and ERG bind a wide range of sites in target genes. Molecular diagnosis of prostate cancer: PCA3 and TMPRSS2:ERG gene fusion. Adamo, P., Ladomery, M. The oncogene ERG: a key factor in prostate cancer. Proc Natl Acad Sci 1990; 87: 84528456.

The mechanism of autoinhibition is performed by two stretches of amino acids that directly flank ERGs EBD. ERG expression is associated with increased risk of biochemical relapse following radical prostatectomy in early onset prostate cancer. If a functional, causal role for the TMPRSS2/ETS fusions is established, the uncovering of a major genetic cause of primary prostate tumors will have a profound impact on our understanding of the molecular mechanism(s) that drive prostate carcinogenesis, and . Adding to this already complex transcriptional regulatory partnership is the inclusion of microRNA-mediated regulation.

Long-term knockdown of the two most common variants of the TMPRSS2:ERG fusion (T1-E4 and T2-E4, see Figure 3) has been successfully performed in mouse xenograft models using small interfering RNA delivered in non-toxic liposomal nanovectors (2-dioleoyl-sn-glycero-3-phosphatidylcholine).

Prostate cancer is the most common non-skin cancer and the second leading cause of cancer death in men in the United States. Nat Genet 2012; 44: 685689. To this effect, ERG cooperates with the SRY-related HMG box transcription factor SoxD to bind the major and minor groove of DNA. TMPRSS2/ERG promotes epithelial to mesenchymal transition through the ZEB1/ZEB2 axis in a prostate cancer model. Increased copy numbers of the TMPRSS2 and ERG loci along with the presence of a deletion fusion are linked poor outcome.177 Single copy fusions are associated with lower Gleason scores, whereas increased fusion copy numbers are associated with higher Gleason scoring.184 This implies that a higher dosage of ERG leads to more severe disease phenotypethis makes sense given ERGs oncogenic role. Proc Natl Acad Sci 2010; 107: 26102615. The small molecule inhibitor, YK-4279, can directly bind to ERG and inhibit its transcriptional activity. Elucidation of the mechanisms of ERG gene rearrangements and expression promises novel therapeutic and diagnostic avenues for prostate cancer.

Although all members of the ETS family bind the core sequence GGA(A/T), differentiation between the classes is associated with the surrounding sequences. The ETS gene family. Thus, it appears that one of ERGs roles is to attenuate androgen-regulated transcription. As we will see later, increased skipping of ERGs exon 7 has also been associated with the progression of prostate cancer.41, Full-length ERG is a 486 amino-acid 54kDa transcription factor.3, 24 What identifies the ETS family uniquely is a specific DNA-binding domain called the ETS DNA-binding domain (EBD).
