Given that ABCB1 expression is functionally associated with docetaxel resistance in CRPC, we sought to determine if there is a link between the expression of GAS5 and ABCB1. In TCGA-PRAD, the expression of ABCB1 was found to be negatively correlated with GAS5 expression (Pearson correlation coefficient r = -0.36, P < 2.2 x 10-16) (Figure 3A). Here, GAS5 is linked to prostate adenocarcinoma.
