In particular, over a 2-fold change of the expression levels was noted in transcripts of CAMTA1, CSMD1, CUL4A, and SLC39A13. Of note, more differentially expressed genes were detected in the CA1 region compared to the DG region, supporting the previous hypothesis of molecular variation in hippocampal subfields during the pathogenesis of depression [53]. This evidence concerns the gene CUL4A and depressive disorder.
