Although the HOXD-AS1 level is significantly higher in prostate cancer patients with a Gleason score of 7(4 + 3)-10 compared with those with a Gleason score of 6–7(3 + 4), the expression level of HOXD-AS1 did not change significantly between benign tissue and cancer tissue [35]. The gene discussed is HAGLR; the disease is prostate carcinoma.
