Figure 6: Protein expression levels of the DEPs selected for validation by western blot analysis in bilateral varicocele group (n = 6) relative to unilateral varicocele group (n = 6). (a) PRDX2. (b) FASN. (c) FN1. Results are expressed as mean ± standard error of the mean and in fold variation to control. DEPS: differentially expressed proteins; PRDX2: peroxiredoxin 2; FASN: fatty acid synthase; FN1: fibronectin 1.
