Apifiny detects in the blood samples 8 circulating PCa-specific autoantibodies (directed to aurora kinase interacting protein 1, CSNK2A2, NK3 homeobox 1, centrosomal protein 164 kDa, 5ʹ-UTR BMI1, chromosome 3ʹ UTR region Ropporin/RhoEGF, ARF6 and desmocollin 3) in a target population of patients with PSA ≥ 2.5 μg/L [23]. This evidence concerns the gene KLK3 and posterior cortical atrophy.
