IGFBP3 and posterior cortical atrophy: We found that the high expression of HERPUD1 (Figure S1A: p = 0.011 for HERPUD1) acted as a protective factor in Pca patients and the high expression of UBE2T, IQGAP3, IGFBP3 and TK1 indicated unfavourable prognoses of Pca patents in the TCGA cohort (Figure S1B‐E: p = 0.00014 for IGFBP3, p < 0.0001 for TK1, p < 0.0001 for UBE2T and p < 0.0001 for IQGAP3).
