To further evaluate the accuracy of our findings, we applied SEEK analysis to search for GEO datasets about the co-expression pattern of Dbx2 and Sox13 target genes, then highlighted the work title that co-occurred with the term ‘Parkinson’, and found that these co-expressed genes tend to be associated with PD (Figure 2F,J and Table S3). This evidence concerns the gene DBX2 and Parkinson disease.
