The relationship between polyamines, NMDA, and depression in suicide completers.

– **Polyamines and Depression in Suicide Completers:**Spermidine has been associated with suicide completers. Studies examining gene expression in the brains of mood-disordered suicide completers revealed altered expression of several polyamine-related genes, including spermidine/spermine N1-acetyltransferase, spermine oxidase, and spermine synthase¹. These findings highlight the dysregulation of the polyamine system in suicide and its importance in the neurobiology of this complex phenomenon.

– **NMDA and Depression in Suicide Completers:** – It is known that NMDA receptors play a crucial role in depression and suicide.
