Genomic Counter-Stress Changes Induced by Mind-Body Practice

ABSTRACT: Mind-body practices that elicit the relaxation response (RR) have been used worldwide for millennia to prevent and treat disease. The RR is believed to be the counterpart to stress response and is characterized by decreased oxygen consumption, increased exhaled nitric oxide, and reduced psychological distress. Individuals experiencing chronic psychological stress have the opposite pattern of physiology and a characteristic transcriptional profile. We hypothesized that consistent, long-term practice of RR techniques results in characteristic changes in gene expression. We tested this hypothesis by assessing the transcriptional profile of whole blood in healthy, long-term practitioners of daily RR practice (group M) in comparison to healthy controls (group N1). The signature obtained has been validated on new subject data. Keywords: time course

The signature obtained has been validated on new subject data. Experiment Overall Design: In the study, the gene expression profiling was performed on individuals with a long-term RR practice (group M; n=19) or those with no prior RR experience; novice (group N1; n=19). Group N1 novices, furthermore, underwent 8-weeks of RR training (Group N2; n=20) for the prospective analysis.As a validation of results , we developed an independent validation sets that includes gene expression profiling on 4 N1, 4 N2 and 6 M subjects.

Microarray comparison of transcriptomic differences between long-term practitioners of the Transcendental Meditation (TM) technique and group-matched non-practitioner controls

Project description:Research on the Transcendental Meditation (TM) technique suggests it is a powerful intervention for reducing the unwanted effects of stress. Investigations of the TM program as a therapeutic intervention include cardiovascular disease (CVD), post-traumatic stress disorder (PTSD), and anxiety disorders. Healthcare utilization studies show reductions in diseases after regular practice of the program. This study compared long-term practitioners of TM (38 ± 4 years) with non-practitioner controls. We used DNA microarray global transcriptomics technologies in Peripheral Mononuclear Blood Cells (PMBCs) to compare a non-practitioner control group (Group III) and a TM-practitioner group (Group IV). Demographically-matched groups of 6 each were studied. These results are expected to be relevant to stress and stress-related diseases such as CVD, diabetes, and PTSD.

Genomic and Clinical Effects Associated with a Relaxation Response Mind-Body Intervention in Patients with Irritable Bowel Syndrome and Inflammatory Bowel Disease

Project description:Patients with chronic illnesses such as Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD) often have reduced quality of life. IBS is characterized by abdominal pain/discomfort associated with altered bowel function, such as diarrhea or constipation, without gross structural changes or inflammation [1]; IBD is characterized by gross inflammation in the gastrointestinal (GI) tract which can result in symptoms such as abdominal pain, cramping, diarrhea and bloody stools. IBS and IBD can profoundly affect quality of life and are influenced by stress and resiliency.The impact of mind-body interventions (MBIs) on IBS and IBD patients has not previously been examined. In this study IBS and IBD patients were enrolled in a 9-week relaxation response based mind-body group intervention (RR-MBI), focusing on elicitation of the RR and cognitive skill building. We performed Peripheral blood transcriptome analysis to identify genomic correlates of the RR-MBI.

Rapid gene expression changes in peripheral blood lymphocytes upon practice of a comprehensive yoga program

Project description:One of the most common integrative medicine (IM) modalities is yoga and related practices. Previous work has shown that yoga may improve wellness in healthy people and have benefits for patients. However, the mechanisms of how yoga may positively affect the mind-body system are largely unknown. Here we have assessed possible rapid changes in global gene expression profiles in the peripheral blood mononuclear cells (PBMCs) in healthy people that practiced either a comprehensive yoga program or a control regimen. The experimental sessions included gentle yoga postures, breathing exercises, and meditation (Sudarshan Kriya and Related Practices â SK&P) compared with a control regimen of a nature walk and listening to relaxing music. We show that the SK&P program has a rapid and significantly greater effect on gene expression in PBMCs compared with the control regimen. These data suggest that yoga and related practices result in rapid gene expression alterations which may be the basis for longer term cell biological and higher level health effects of these practices. Comparison of genome-wide gene expression upon practice of a comprehensive yoga program.

Prediction of Recurrence-Free Survival in Postoperative NSCLC Patients—a Useful Prospective Clinical Practice

Project description:Background: One of the main fields of lung cancer research is identifying patients who are at high risk of post-resection recurrence. Individual recurrence risk evaluation by accurate but simple and reproducible method is needed for the clinical practice. Results: The log-rank test and further selection by our criteria of assayability generated 87 genes from microarray data with significant level 5%. Of these, by PTQ-PCR, the expression of most significant 18 genes was obtained. Using these gene expression information and clinical parameters, by stepwise variable selection method, the recurrence prediction model, which composed of 6 genes (CALB1, MMP7, SLC1A7, GSTA1, CCL19, IFI44) and pStage and cell differentiation, were developed. Validation into the two independent cohorts showed good results of the proposed model (p=0.0314, 0.0305, respectively). The predicted median recurrence-free survival times for each patient were reflected real ones well. Conclusions: Our method of individualized recurrence risk prediction is accurate, technically simple and reproducible to be used in clinical practice. Therefore, it would be useful in customizing the lung cancer management strategies. Keywords: Recurrence Free Survival Analysis
