Study Details

Study Description

Brief Summary

This study will leverage extracted leukocyte DNA specimens from a completed NIH-funded project to examine the efficacy of a behavioral intervention model that reduced stimulant use on DNA methylation over 6 months.

    Arms and Interventions

    Arm Intervention/Treatment
    Leukocyte DNA Samples

    Leukocyte DNA specimens extracted from participants enrolled in a completed NIH funded trial will be examined to determine if prior exposure to different behavioral interventions modifies DNA methylation patterns over 6 months.

    Outcome Measures

    Primary Outcome Measures

    1. Neuroimmune Signaling [6 Months]

      Decreased methylation of genes for genes relevant to neuroimmune signaling such as beta-2 (β2) adrenergic (i.e., ADRB2), glucocorticoid (i.e., NR3C1 and FKBP5), and oxytocin (i.e., OXTR) receptors as well as brain-derived neurotrophic factor (BDNF) promoters.

    Secondary Outcome Measures

    1. DNA Methylation Pathways [6 Months]

      Pathway Analyses examining alterations in methylation patterns relevant to immune and neural function.

    2. Immune Dysfunction [6 Month]

      Soluble makers of monocyte activation such as soluble CD14 (sCD14) and inflammation such as soluble Tumor Necrosis Factor - Alpha Receptors I and II (sTNF-aRI and sTNF-aRII)

    3. Dysregulated Metabolism of Amino Acid Precursors for Neurotransmitters measured via high-performance liquid chromatography (HPLC) [6 Months]

      Using HPLC, higher kynurenine/tryptophan (K/T) ratio indexes catabolism of tryptophan into kynurenine and other downstream catabolites versus serotonin over 6 months. Using HPLC, the phenylalanine/tyrosine ratio reflects decreased metabolism of tyrosine into catecholamines such as dopamine over 6 months.
