Finally, we downloaded these differential genes through the TCGA database and analyzed the linear correlation with the seq-HTSeq-FPKM-UQ value of FAM64A in PCa patients, and found that the expression levels of SNHG18, IFIT3, OAS1, PMSB9, OAS2, UBE2L6, IGFBP3, ZNF48, and the expression level of FAM64A are linearly correlated and consistent with the sequencing results (Fig. 5i). Here, SNHG18 is linked to posterior cortical atrophy.
