The result of this inference was further supported by the TCGA and GEO (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE21032) datasets that found PCAT7 to be markedly elevated in PCa tissues compared with adjacent normal tissues (ANT) (Fig. 1B,C and Fig. S1a). Here, PCAT7 is linked to posterior cortical atrophy.
