XPO1 and posterior cortical atrophy: 7 XPO1, PDCD6IP, and FASN stainings were observed in all samples, mainly in epithelial cells. We noticed that the XPO1 expression varied within and between the nuclear and cytoplasmic compartments. Nuclear XPO1 expression was present in 98.4% of cases and cytoplasmic expression was observed in 74.5% of cases. XPO1 showed strong nuclear and low cytoplasmic expression in luminal cells in NAP.7 With the progression of PCa and increasing GS, cytoplasmic XPO1 expression increased (Figure 2).
