Recent studies point to a consistent overexpression of Monocarboxylate Transporter 2 (MCT2) in PCa [2, 3], which, in terms of sensitivity and specificity to detect malignant glands was comparable to Alpha-Methyacyl-CoA-Racemase (AMACR) an established prostate cancer biomarker. This evidence concerns the gene SLC16A7 and Familial prostate cancer.
