To verify whether these three secretory proteins contribute to ENZ resistance in PCa, we introduced another PCa cell line, LNCaP, which is androgen‐dependent.[14] Interestingly, compared to the other groups, ECM1 significantly promoted the growth of PCa cells in the presence of ENZ addition (Figure 2E; Figure S2A, Supporting Information). The gene discussed is ECM1; the disease is posterior cortical atrophy.
