HOXB13 and prostate cancer: Previously, we reported a strong correlation between PSMA and HOXB13 expression in The Cancer Genome Atlas Prostate Adenocarcinoma (n = 492, r = 0.51, P = 2.2 × 10–37) and the Stand Up to Cancer–Prostate Cancer Foundation (n = 444, r = 0.54, P = 3.66 × 10–10) datasets, which are based on RNA sequencing (3).
