COST Action MitoEAGLE

The aim of this study was to define the transcription profiles of the molecular markers of mitochondrial biogenesis and fusion/architecture, as well as the markers of mtDNA copy numbers in the peripheral blood mononuclear cells (PBMCs) from war veterans with/without post-traumatic stress disorder (PTSD). Also, in order to define signaling molecules involved in changes of transcription profiles immortalized human males monocytes were exposed in vitro to hormonal markers of PTSD.

RQ-PCR-results showed that the transcription profiles of above mentioned markers were disturbed, with high individual variability within the groups. A significant increase in the expression of the PPARGC1A transcript was observed in a group of subjects who currently have PTSD, as well as in the subjects with “life-time" PTSD, compared to healthy controls. PPARGC1B, NRF2 and MFN2 transcripts increased only in PBMCs of “life-time"-PTSD, while the level of transcripts for other investigated genes and the ratio of markers of mtDNA copy numbers showed no significant difference between groups. The in vitro results showed parallelism in the transcription profile of molecular markers of mitochondrial biogenesis with results obtained using the PBMCs of the PTSD study.

It should be emphasized that all results should be considered as preliminary because the technical/time constraints did not allow the analysis of a larger number of PTSD subjects. However, the results are first findings in the field and can be used as a solid base for further extensive multidisciplinary research in order to clarify the molecular mechanisms for the prevention and treatment of trauma-induced pathological conditions.
