The GS 8–9 UV proteomes furthermore contained epididymis secretory sperm binding protein, the tumour-associated squamous cell carcinoma antigen (SCCA1/SCCA2 fusion protein), CEACAM7—a member of the carcinoembryonic antigen family of proteins [42], F-box only protein 50, and glial fibrillary acidic protein, which may have regulatory roles in immune phenotypes of PCa [43] as well as cellular retinoic acid-binding protein 1 (CRABP1), which is implicated in PCa progression [44]. Here, CAT is linked to posterior cortical atrophy.
