Oxidized DJ-1 Levels in Urine Samples as a Putative Biomarker for Parkinson’s Disease

Figure 3

Comparison of OxiDJ-1 levels from patient urine samples using Western blot analysis. (a) Urine samples of non-PD controls (34, 35, 36, 39, 41, 43, 44, 46, 50, 55, 60, 101, 105, 108, 109, 112, 113, 115, 116, 117, 120, and 121) or PD patient (1, 2, 3, 4, 5, 9, 10, 12, 13, 15, 17, 20, 21, 23, 24, 25, 28, 29, 30, 71, 72, 74, 75, 76, 77, 78, 79, 80, 81, 84, 86, 88, and 89) were subjected to Western blot. The numbers at the top of the images are the patient numbers. (b) OxiDJ-1 levels were normalized with total protein levels determined by Ponceau S staining, and their ratio was diagramed. Student’s t-test was used for this analysis. (c) Gender-grouped OxiDJ-1 levels were analyzed. All comparisons with one-way ANOVA were not significant.
