摘要

Background

Major depressive disorder (MDD) is a prevalent mental health condition, wherein the JAK/STAT signaling pathway serves as a potent cellular mechanism implicated in its pathophysiology. Increased expression of JAK2, STAT3, and subsequently IDO1 genes appears to be linked to depressive symptoms. With their antioxidant capabilities and improved absorption due to the nano formula, selenium nanoparticles could potentially modulate this molecular pathway. This study aimed to assess the impact of nano-selenium supplementation on the expression of JAK2, STAT3, and IDO1 genes in patients with MDD.

Methods

A triple-blind, randomized, placebo-controlled trial was conducted at the Psychosomatic Clinic of Imam Khomeini Hospital Complex. A total of 50 participants, newly diagnosed with MDD were randomized to either a nano-selenium (55 µg/day) or placebo group for 12 weeks. All participants were receiving their standard treatment (sertraline 50 mg/day). Blood samples were collected at baseline and post-intervention to measure the gene expression using RT-qPCR.

Results

At the end of the study, both groups showed reductions in JAK2 and STAT3 relative gene expression after 12 weeks (P < 0.05). Although the reduction was more in the nano-selenium group, the between-group differences were not statistically significant.

Conclusions

This study is the first to examine nano-selenium as a novel potential adjunct treatment for MDD. Though the degree of reduction in JAK2 and STAT3 levels was greater within the nano-selenium group, it appears that additional investigations are needed to elucidate its effects.

Trial registration

The research received approval from the Research Ethics Committees of Iran University of Medical Sciences (Approval ID: IR IUMS.REC.1402.206, dated 2023-06-13) and was duly registered with the Iranian Registry of Clinical Trials (IRCT; registration number: IRCT20091114002709N62, dated 2023-07-29).

Graphical Abstract

This research represents the first human trial investigating the effects of the nano-selenium formulation on the expression of a key signaling pathway associated with major depressive disorder.
