UROC28 protein was detected in serum by Western slot blot analyses, and a significant higher UROC28 protein level was found in sera of prostate cancer individuals compared with normal individuals and individuals with nonmalignant prostatic hyperplasia.
Probes for fluorescence in situ hybridization for the BMP, BMP5, BMP7, and UC28 gene loci were developed and applied to archival sections with areas of adjacent benign epithelium, high-grade prostatic intraepithelial neoplasia, and prostate carcinoma.
Additionally, by immunoblotting, PBOV1 protein levels differed significantly between Grade Group 2 (GS 3 + 4) and Grade Group 3 (GS 4 + 3) PCa samples (P = 0.028).
