MAZ and posterior cortical atrophy: To investigate the mechanism responsible for MAZ overexpression in PCa tissues, we further analysed the PCa dataset from TCGA-PRAD [32] and GSE74685 and found that the frequencies of recurrent gains (amplification) in TCGA-PRAD and GSE74685 were 6.91 and 28.2% respectively (Fig. 2a and b).
