We noticed that UCA1 expression was negatively correlated with miR-204 expression in PCa (r = −0.2865, P=0.0431), suggesting that the loss of function of miR-204 may be not only due to its lowered expression but also due to intimate association with up-regulated UCA1 expression in this malignancy (Figure 4C). Here, UCA1 is linked to posterior cortical atrophy.
