(a) Schematic flow of the selection of 11-gene panel for
PCa EV Digital Scoring Assay, including ACP3, FOLH1, HOXB13, KLK2, KLK3,
KLK4, MSMB, RLN1, SLC45A3, STEAP2, and TMPRSS2.
(b) Box plot of the percentile of expression level of the
11-gene panel in primary PCa patients’ tissues from TCGA, PCa cell lines
from CCLE, and immune cells from DMAP. Each dot represents the mean of
percentile of each maker. *Expression of STEAP2,
SLC45A3, and KLK4 are not available in
DMAP. CCLE, Cancer Cell Line Encyclopedia; DMAP, Differentiation MAP dataset;
EV, extracellular vesicle; PCa, prostate cancer; TCGA, The Cancer Genome
Atlas.
