In order to explore whether MALAT1 and MYBL2 are related to the mTOR pathway in PCa, we utilized mTOR pathway inhibitor rapamycin and found that it reduced the growth rate (Figures 3(a) and S1G) and the number of colonies of PCa cell lines significantly (Figures 3(b) and S1H). This evidence concerns the gene MYBL2 and posterior cortical atrophy.
