Of particular interest, significant correlations were observed between GALNT7 and CAMKK2, TMPRSS2, CCND1 and FKBP5. These results indicate that GALNT7 levels directly correlate with AR activity in prostate cancer and suggest GALNT7 levels may mark those developing relapse to castrate resistant disease. Here, TMPRSS2 is linked to Familial prostate cancer.
