On the basis of our clinical cohort of PCa sample tissues, the Taylor and TCGA datasets, the Spearman Correlation analysis clearly presented a negative correlation between MYPT1 mRNA and miR-30d expression in PCa tissues (for our clinical cohort: Fig. 4a, for Taylor and TCGA datasets: Additional file 1: Figure S10). This evidence concerns the gene PPP1R12A and posterior cortical atrophy.
