MUC1 and posterior cortical atrophy: Lapointe and colleagues identified three subtypes of PCa based on differential gene expression profiles, in which MUC1 was highly expressed and positively stained in subtypes II and III, which correlated with a high risk of invasiveness and recurrence of PCa (P = 0.003), suggesting that MUC1 can serve as a molecular marker for the heterogeneity of PCa [148].
