ST6GALNAC1 and posterior cortical atrophy: Analysis of previously published RNA-Sequencing data from 7 PCa patients [63] showed that ST6GalNAc1 gene expression is also strongly down-regulated following ADT in all cases (Figure 1H), suggesting that ST6GalNAc1 is also regulated (either directly or indirectly) by androgens in vivo, and is clinically relevant in patients.
