Similar to these two studies, our study used four AR-positive PCa cell lines, LNCaP (metastatic EA PCa), C4-2B, and 22Rv1 (EA CRPC), and MDA PCa 2b (AA PCa), as our in vitro cell model to test the efficacies of miR-99b-5p alone and in combination with Enz or Abi in PCa. Here, AR is linked to posterior cortical atrophy.
