For verification, we compared the differential expression of DDX49 between tumour and normal tissues based on the RNA sequencing data from the GEO database, which included GSE29079 (p = 0.0006), GSE25183 (p = 0.0031), GSE46602 (p = 0.0030), GSE 38,241 (p < 0.0001), and GSE69223 (p = 0.0165), and found increased DDX49 expression levels in PCa tissues compared with normal tissues (Fig. 1B–F). This evidence concerns the gene DDX49 and posterior cortical atrophy.
