In order to validate the results obtained in our PP cohort, the expression of NCL in PCa was evaluated by the analysis of the available TCGA and GTEx cohorts for PCa patients using the XENA platform (including 100 normal tissues, 52 solid normal tissues (peritumoral normal tissue), and 495 HNPC) (Figure 1c). The gene discussed is NUCLEOLIN; the disease is posterior cortical atrophy.
