Here, experimental analyses of gene expression data in The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA PRAD) [24] and the metastatic CRPC Stand Up to Cancer/Prostate Cancer Foundation (SU2C/PCF) [33] cohorts show a significant correlation between the expression of AR and GALNT7 in both clinical prostate cancer datasets (Supplementary Fig. 4A, B). Here, GALNT7 is linked to prostate cancer.
