NRP1 and ovarian adenocarcinoma: A low NRP1 protein expression was also confirmed in UWB and UWB-BRCA cells, derived from serous OC, whilst SKOV3 cells, derived from the ascites of an ovarian adenocarcinoma patient, showed a high basal expression of NRP1 protein (5 fold, with respect to UWB cells) (Fig. 3b).
