When linear regression analysis was conducted to assess correlation between AR activity score and miR targets in CRPC patient tumours (n = 122) from SU2C [32], a significant positive correlation of ARHGDIA expression with AR activity was found (P = 5 × 10−8) (Fig. 7gi), while TAGLN2 is significantly negatively correlated (P = 0.03) (Fig. 7gii). This evidence concerns the gene TAGLN2 and neoplasm.
