Interestingly, Pearson correlation analysis showed a positive association between circDVL1 and PCDH7 mRNA levels in 18 paired ccRCC samples, while both circDVL1 and PCDH7 expression were negatively correlated with miR-412-3p expression (Fig. 8D-F). Here, PCDH7 is linked to nonpapillary renal cell carcinoma.
