NOS1 and posterior cortical atrophy: Two of the molecules investigated are NitricOxide (NO), which has been shown to be related tothe aetiology of PCa, and nitric oxide synthase (NOS),the enzyme that enables it to be synthesised [1], [4], [9].Some studies have shown that NO levels rise withinflammation and malignancy and may have a bimodalbehaviour in PCa development [10].
