Multidimensional analysis of twin sets during an intensive week-long meditation retreat

ABSTRACT: Meditation and other alternative practices have long been known to promote various health benefits, presumably by fostering a blood and tissue environment that enhances resilience to stress. Here, we used an integrated, multidisciplinary approach that couples quantitative electroencephalography (qEEG), biometrics, molecular, and biochemical data at multiple time points to investigate the impact of mind-based interventions on the body in a cohort of twins during an intensive week-long meditation retreat. We aim to show the feasibility of a novel design aimed to address individual changes controlling for intersubject trait variation (via twin control) and explore the role of genetic background on multi-omic factors during meditation. Interestingly, twin pairs showed significant spectral power correlations while in separate rooms and only one twin was meditating. These similarities were not observed in mismatched twin pairs. Heart rate dynamics assessments showed alignment among twin pairs that were absent between unmatched pairs. In addition, changes in gene expression, metabolites, and cytokines in blood plasma associated with specific meditative states showed patterns of change related to time points. Twin sets were similar in multiple domains before the start of the retreat, showed considerable divergence at the mid-point, and looked more similar by the end of the retreat. To our knowledge, this study is novel within the twin research paradigm and is a first step toward exploring the effects of meditation in twins.

Project description:DNA methylation appears to play an essential mechanistic role in the pathogenesis of ALL, thereby potentiate its use as a biomarker for diagnosis and prognosis (Milani, Lundmark et al. 2010; Geng, Brennan et al. 2012; Sandoval, Heyn et al. 2013), and even a potential target of novel therapeutic approaches in ALL. In present study, we collected blood specimens for 4 pairs of monozygotic twins (MZ) and 1 pair of dizygotic twin (DZ) that are discordant for ALL. We sought to comprehensively assess the magnitude of genetic and epigenetic differences between ALL-affected and unaffected twins. we conducted whole genome and whole methylome sequencing on these five pairs of ALL-discordant twins. We also examined both the MZ and DZ twins using whole-genome bisulfite sequencing (WGBS). At first, the methylation differences across the genome were addressed globally by Circos software. And then tried to characterize the co-twin methylation divergence in specific genomic regions between ALL-discordant twin pairs. These patterns of dynamic co-twin methylation changes in these discordant ALL samples were generally consistent among MZ and DZ twins, indicating similarities of methylation abnormalities. As a result, 780, 566, 309, 293 and 2110 DMRs were identified, with a similar distribution pattern across different genomic elements among the five twin pairs.Then we annotate whether these DMRs were located in regulatory elements and identification of genes with recurring methylation alterations in a cohort of ALL patients.
