PDCD4 and posterior cortical atrophy: Additionally, we found a moderate negative correlation with EPCART expression and PDCD4 protein expression in our Tampere primary PCa specimens (Spearman’s ρ = −0.38; n = 17) [20], but not with PDCD4 mRNA expression (Spearman’s ρ = 0.13; n = 28) (Supplementary Table 9), supporting the idea that expression of EPCART and PDCD4 protein regulation are linked.
