To further measure the relationship between the expression of FZD5 and miR‐212‐5p expression in PCa, Western blot showed that the expression of FZD5 was decreased significantly after the transfection of miR‐212‐5p mimics, while Knockdown LINC00115 also decreased FZD5expression. Here, LINC00115 is linked to posterior cortical atrophy.
