Fig. S5. (a) Distribution of transcript levels of total MacroH2A1, MacroH2A1.1 and MacroH2A1.2, assessed by RT-qPCR and normalized to GUSB mRNA levels, in androgen-receptor positive prostate cancer cell lines (22Rv1, LNCaP and VCaP), and in androgen-receptor negative prostate cancer cell lines (DU145 and PC-3). Here, GUSB is linked to Familial prostate cancer.
