We found that 12 out of 15 DLPFC DEPs (ACADVL, CACNA2D1, CD59, CYB5B, DPP6, EXOC7, FRRS1L, RAC1, RHOB, TPM3, WDFY1, YWHAE) and five out of nine sgPFC DEPs (APOA1, NDRG2, PABPC1, RAB5B, RPS8) were associated with both expression and target 3′-UTR sequences of PTSD regulated miRNAs (Additional file 9: Table S8). This evidence concerns the gene RAC1 and post-traumatic stress disorder.
