AR and familial pancreatic carcinoma: Several other studies demonstrated oncogenic effects of XIST through different miRNA/gene axes, such as miR-101/EZH2 (enhancer of zeste 2 polycomb repressive complex 2 subunit) in gastric cancer, miR-124/AR (androgen receptor) in bladder cancer, and miR-133a/EGFR (epidermal growth factor receptor) in pancreatic cancer, to commonly affect growth, invasion and migration [79,80,81].
