ERG and prostate carcinoma: Using the expression data of our series of prostate carcinomas subtyped for ETS rearrangements [6], we show that both PC3 and MDA-PCa-2b cells have co-overexpression of ETV1 and ETV4, both ETS in higher levels than those of ERG in VCaP cells, the in vitro model of the TMPRSS2-ERG rearrangement [12].
