Comparative analyses of HOX gene mRNA expression using publicly-available RNA-Seq datasets of adult human prostate tissues demonstrated that HOXB13 is the highest-expressed (Pflueger et al., 2011; Robinson et al., 2015) HOX gene across benign epithelium, tumor, and metastatic tissue; HOXA10 is the next-highest (FPKMs HOXB13 vs. HOXA10: benign, 167.69 vs 38.53; primary tumor, 197.40 vs 35.63; metastasis, 149.44 vs 28.03, Figure 2A; Bhanvadia et al., 2018). This evidence concerns the gene HOXA10 and neoplasm.
