Gene expression signatures in patients with posttraumatic stress disorder (PTSD) and healthy controls

To investigate gene expression signatures in PTSD, we used microarray and performed blood-based transcriptome profiling. Our analyses identified key genes and molecular pathways that can be centrally involved in the etiology of PTSD. The blood sampling was performed around noon (before lunch), between 11:30 AM and 12:30 PM. Gene expression in blood was measured for 32 women with PTSD and 16 healthy control women.
