DLX1 and cancer: Similarly, the comparison of histologically benign radical prostatectomy samples to incidental samples from cancerous patients (RP-B vs. CP-IPCa) revealed statistically significant differential expression (p ≤ 0.05) for six of the eight genes, with the exception of TDRD1 and DLX1. Also these observations may be due to the aforementioned field effects in cancer-associated or adjacent tissues.
