Stable overexpression and knockdown of mutant- or wild type SPOP in VCaP prostate cancer cells

Purpose: Little is known about the interplay of driver mutations that never co-occur within the same cancer cells. The latter scenario has been identified in prostate cancer where recurrent gene fusions involving the oncogenic ERG transcription factor and point mutations in the ubiquitin ligase adaptor SPOP are strictly mutually exclusive. We show that ERG and mutant SPOP – even though oncogenic on their own – are together synthetic sick. Description: RNA-Seq of lentiviral-transduced VCaP cells with stable knockdown of wild type SPOP (2 x hairpins) or stable overexpression of either wild-type or mutant SPOP (Y87C, F102C, W131G).
