XIAP and posterior cortical atrophy: Densitometric analysis of blots corresponding to the total number of patient samples showed differences in the ratios of XIAP/Lamp1, cIAP-2/Lamp1, and Survivin/Lamp1 between the two patient groups, with AA-PCa patients showing significantly higher expression of XIAP (P<0.001), c-IAP-2 (P<0.01), and Survivin (P<0.05) (Fig 4A–4C).
