Western blot analysis data (Fig. 2) demonstrated exceptional enrichment of exosomal markers (TSG 101, CD9) and epithelial cell adhesion molecule (EpCAM), as well as moderately enriched prostate tumor-marker PSMA in exosomes when compared to relatively stable α-tubulin levels in cells and exosomes. The gene discussed is FOLH1; the disease is prostate neoplasm.
