Nitric oxide and major depression.
    Nitric oxide : biology and chemistry, 2011, Apr-30, Volume: 24, Issue:3

    Nitric oxide has been known to play a significant role in the pathophysiology of various disorders of the body. Despite its very short half-life, nitric oxide is known to modulate various neurotransmitter system(s) in the body and thus is speculated to play an imperative role in the pathogenesis of neurological disorders. This "wonder" molecule has been often found to possess a "dual role" in many neurological disorders of the body. Evidences have shown its prominent role in the pathogenesis of major depression. Nitric oxide modulates norepinephrine, serotonin, dopamine, glutamate, the major neurotransmitters involved in the neurobiology of major depression. The nitric oxide modulatory activity of various new generations of antidepressants has been demonstrated. Clinical studies have also confirmed the nitric oxide modulatory activity of various antidepressants particularly belonging to the class of selective serotonin reuptake inhibitors. The present review attempts to discuss the role of nitric oxide in the pathophysiology of major depression. Further, the involvement of nitric oxide system in the mechanism of various antidepressants has been discussed in detail. Nitric oxide based antidepressants can be the future drugs of choice for major depression, particularly in the treatment of pharmacoresistant depression.

Nitric Oxide and Cyclic Guanosine Monophosphate Signaling Mediates the Antidepressant Effects of Acupuncture in the Rat Model of Chronic Unpredictable Mild Stress.
    Medical science monitor : international medical journal of experimental and clinical research, 2019, Nov-30, Volume: 25

    BACKGROUND Depression is a major mood disorder. Some patients have been reported to improve following acupuncture. This study aimed to investigate the effects of acupuncture on behaviors associated with depression in the chronic unpredictable mild stress (CUMS) rat model. The expression of signaling pathway components of nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) in the rat hippocampus and plasma were also measured. MATERIAL AND METHODS Male Sprague-Dawley rats (N=40) were divided into the control group (N=10), the model group (N=10), the acupuncture group (N=10), and the non-acupuncture group (N=10). The rat model was established by orphaning combined with chronic unpredictable mild stress (CUMS) for six weeks. The acupuncture group was given 21 days of treatment using acupoints (AP) or non-acupoints (NP). Rat behaviors associated with depression were tested using the sucrose preference test (SPT), the open field test (OFT), and the elevated plus maze (EPM) test. Enzyme-linked immunoassay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the expression of inducible nitric oxide synthase (iNOS), neuronal nitric oxide synthase (nNOS), and the N-methyl-D-aspartate (NMDA) receptor subunits, NR1, NR2A, and NR2B in the rat plasma and hippocampus. RESULTS Acupuncture reversed the behaviors associated with depression in the CUMS rat model and reduced the expression of components of the NO and cGMP pathway in the rat hippocampus and plasma. CONCLUSIONS In the CUMS rat model, treatment with acupuncture reduced behaviors associated with depression, and these effects were associated with changes in the NO and cGMP signaling pathway.
