According to the latest estimates from the World Health Organization, individuals commit suicide every 40 seconds. Suicide is the fourth leading cause of death for people between the ages of 15 and 19, and despite numerous programs of psychological support and awareness campaigns, suicide rates have increased rapidly in recent years.
Scientists said, “Expression of blood genes is very useful in understanding the molecular changes in suicide.” They analyzed blood and brain samples belonging to those who committed suicide and those who died in other situations.
The team found that the first group had significant changes in the expression of genes involved in the response to stress, along with circadian rhythms, immune responses, and telomeres (participants at the ends of chromosomes that protect them from injury). I noticed that there was.
Researchers said identifying blood biomarkers is an important step in developing blood tests that can determine a person’s suicidal tendency.
“As far as we know, this is the first study to analyze blood and brain samples in a well-defined population of MDDs that show significant differences in gene expression associated with complete suicide,” responds. The author, Dr. Adolfo Sequeira, said. Department of Psychiatry and Human Behavior, University of California, Irvine School of Medicine.
