For example, pseudogene OCT4-pg4 regulates OCT4 expression by competing for miR-145 in hepatocellular carcinoma [23]; pseudogene TUSC2P promotes TUSC2 function by binding multiple microRNAs [24]; a FTH1 gene-pseudogene-microRNA network modulates development of prostate cancer [25]. Here, POU5F1 is linked to Familial prostate cancer.
