Comparative Analysis of EV Proteins between Prostate Cancer Cases and Non-prostate Cancer Controls. To distinguish the EV protein characteristics between prostate cancer cases and non-prostate cancer controls, we compared and identified the upregulated or downregulated EV proteins, then summarized the overlapped EV proteins across three search strategies. (a–c) Volcano plots (Direct-DIA, GPF-DIA, and DDA-DIA, respectively) for statistical differences between the two groups (prostate cancer cases vs. non-prostate cancer controls) were assessed with the Mann-Whitney test. (d) Venn diagram for assessing the overlap of differentiated EV proteins across three search strategies.
