To clarify the mechanism by which MNX1‐AS1 regulates prostate cancer cell function, we further tested the expression levels of proliferating cell nuclear antigen (PCNA), phospho‐histone H3 (PH‐3), E‐cadherin, N‐cadherin and vimentin in prostate cancer DU145 and PC3 cells. Here, MNX1 is linked to prostate cancer.
