Ficantly higher in expression in the nonrecurrent group compared with biochemically recurrent patients (p 0.05). In addition, we analyzed extracapsular (n 23) and organ-confined (n 19) direct-EPS samples for the expression of MME using a commercially available ELISA, and found a similar trend in this new set of samples (p 0.07) (Supplemental Fig. S5B). PARK7 had a threefold difference by QSpec wit
