Abstract
- Background: Suicide Attempts are the main complications of Major Depressive Episodes and are difficult to predict. There is still a lack of knowledge about its neurochemical aspects. There is increasing evidence that Brain-derived neurotrophic factor (BDNF) and Nerve growth factor (NGF) play a role in the pathophysiology and treatment of depression by binding and activating cognate receptors Tyrosine Kinase B (TrkB) and Tyrosie Kinase A (TrkA), respectively. This study was conducted to examine whether BDNF and / or TrkB as well as NGF and / or TrkA expression profiles were changed in the hippocampus of postmortem brain of individuals with depression who committed suicide. Subjects and methods: This study was conducted with the brain tissue of 61 victims who died as a result of suicide due to depression and 25 people who died due to traffic accidents. The psychiatric history of the cases was determined by the psychological autopsy method. Samples were taken from the hippocampus region of the brain at the forensic medicine institution. After storage under appropriate conditions, protein and mRNA levels of BDNF, TrkB, NGF and TrkA were determined in the genetics laboratory. Results: Average age of the suicide group was 30 and the average age of the control group was 24.5. The suicide group consisted of 70.5% male and 29.5% female cases. There was no significant difference between the groups in terms of age (p=0.062) and gender (p=0.718). BDNF, NGF, TrkA and TrkB values were found to be lower in the suicide group compared to the control group and there was a significant difference between the groups (p=
