Additionally, these observations align with studies demonstrating that PARP‐1 and PAR are elevated in PCa compared to benign prostatic hyperplasia in a Chinese cohort (Wu et al, 2014) and that PARP‐1 protein is elevated in cases of primary PCa as compared to normal controls (Salemi et al, 2013). Here, PARP1 is linked to benign prostatic hyperplasia.
