GATA3 and urinary bladder cancer: The significant association of AR expression with CK20 and GATA3 (markers for luminal bladder cancer) and the inverse correlation with p63, a marker for basal subtype, in muscle-invasive carcinomas is consistent with earlier RNA data linking high AR expression levels to the luminal papillary molecular subtype of urothelial neoplasms, which is overrepresented in men [44].
