AR and Familial prostate cancer: On the other hand, because the majority (73%; 170/232) of our prostate cancer tissues expressed low levels of DDB2 (Supplementary Table 2), when only those low-level DDB2 tumors were considered in comparison, it became more obvious that high expression levels of both NRIP and AR were more frequently detected in the cribriform tumors (odds ratio: 4.83, 95% confidence interval: 2.09-11.15, P < 0.005), while other combinations of expression were found more frequently in non-cribriform tumors (Supplementary Table 2).
