AR and prostate cancer: Interestingly, our bioinformatic analyses of the ADCA cell line signature shows enrichment with castration-resistance signatures based on expression data from human prostate cancer patients (Best and Stanbrough signatures), consistent with increasing evidence supporting AR-independent mechanisms of castration-resistance (Beltran et al., 2014; Vlachostergios et al., 2017; Watson et al., 2015).
