TGM2 and posterior cortical atrophy: Meta-analysis of TG2-MUC1 co-expression in seven publicly available PCa data sets showed a correlation between TG2 and MUC1 expression in five clinical studies for a total of 868 patients [44–47] validating the expression reported in PCa cell lines, indicating that the TG2-MUC1 axis could be a PCa hallmark (Supplementary Fig. 10).
