Project description:Comparison of transcript abundance estimates derived from DBS vs saliva vs gold standard peripheral blood mononuclear cell (PBMC) samples. Gene expression profiling was conducted using parallel collection and assay of venipuncture blood samples (PBMC), DBS samples, and saliva. Data come from 58 community dwelling adults recruited from the Los Angeles metropolitan area. Analyzed data include basic demographic characteristics (age, sex, race/ethnicity) and body mass index (BMI) as well as RNA indicators of major leukocyte subset prevalence (i.e., estimated abundance of mRNA for CD3, CD4, CD8, CD19, FCGR3A/CD16, NCAM1/CD56, and CD14; all provided here as log2-transformed values of normalized gene expression data). Categorial variables were coded 0=no/absent and 1=yes/present.

Project description:Analysis of transcript abundance estimates as a function of child soldier status, PTSD symptoms, and psychological resilience. Gene expression profiling was conducted on dried blood spot (DBS) samples collected from community dwelling adolescents and young adults in Nepal. Approximatley half of the sample were former child soldiers in the Nepal People's War and the other half were demographically similiar civilian non-combatants. In addition to basic demographic characteristics (age, sex, ethnic minority status, social caste status, education level), participants were also assessed on syptoms of post-traumatic stress (PTS, assessed by a culturally adapted version of The Child PTSD Symptom Scale; Kohrt BA, et al. (2011) Validation of cross-cultural child mental health and psychosocial research instruments: adapting the Depression Self-Rating Scale and Child PTSD Symptom Scale in Nepal. BMC Psychiatry 11(1):e127, with higher values indicating greater PTSD symptoms) and psychological resilience (assessed by a culturally adapted version of the Resilience Scale; Wagnild GM & Young HM (1993) Development and psychometric evaluation of the Resilience Scale. Journal of Nursing Measurement, with higher values indicating greater resilience). Dichotomous variables were coded 0=no/absent and 1=yes/present. Valid gene expression data are available for 254 samples.

Project description:This study tested the effects of repeated social defeat (RSD) on gene expression in peripheral blood mononuclear cells (PBMC), and examined the extent to which these effects were abrogated by depletion of CD11b+ cells (monocytes). Study Type: Risk prediction Gene expression profiling was carried out on peripheral blood mononuclear cell (PBMC) mRNA samples collected from 18 mice randomized to either 6 cycles of repeated social defeat (RSD, n=9) or to home cage control (HCC, n=9) conditions. PBMC samples were pooled into 3 groups of n=3 samples in each condition, and Illumina Mouse Ref-8 BeadArray assays were performed on approximately 1 million total PBMC and 1 million PBMC from which CD11b+ cells were immunomagnetically depleted by MACS. The primary research questions are 1) whether expression of pro-inflammatory genes is altered by RSD, and 2) whether depletion of CD11b+ cells (monocytes) abrogates these effects.

Project description:Analysis of transcript abundance estimates as a function generalized purpose in life and work-related dimensions of meaning. Gene expression profiling was conducted on peripheral blood samples collected from adult male employees of a Japanese technology firm. In addition to health-relevant background characteristics (age, indcome, body mass index/BMI, smoking history, heavy alcohol consumption history), participants were also assessed for hedonic and eudaimonic dimensions of generalized well-being (assesed by the Short Flourishing Scale, Keyes, C (2006). The Mental Health Continuum-Short Form (MHC-SF) for adults) and work-specific variables including job evaluation (assessed by a12-item scale tapping both perceived significance of the firmâs work, through items such as âI am proud of my companyâ and âI think my company is really good,â as well as perceived significance of oneâs own contribution to the firm's work, through items such as, âI think other employees within my company respect my workâ), and workplace interdependence and independence of the self and coworkers (using the Singelis Self-Construal Scale, Singelis, T. M. (1994). The Measurement of Independent and Interdependent Self-Construals. Personality and Social Psychology Bulletin, 20(5), 580â591). Higher values of each scale score indicate greater levels of well-being, job satisfaction, etc. Dichotomous variables were coded 0=no/absent and 1=yes/present. Valid gene expression data are available for 106 participants.

Project description:Individual differences in basal leukocyte gene expression profiles as a function of child's and parent's perception of family stress, and as a function of parent's psychological well-being. Gene expression profiling was carried out on peripheral blood mononuclear cell mRNA samples collected from 273 individuals (129 parent:child pairs + 15 parent-or-child) who were also assessed on their perceptions of family stress (both parent's and child's perception). Each dyad is labeled by a case ID, with p suffix indicating parent's gene expression profile and c suffix indicating child's gene expression profile. Variations in gene expression are analyzed as a function of both parent's perception of family stress and child's perception of family stress (using UCLA Life Stress Interview, as previously described: Hammen C (1991) Generation of stress in the course of unipolar depression. J Abnorm Psychol 100:555-561; Adrian C, Hammen C (1993) Stress Exposure and Stress Generation in Children of Depressed Mothers. Journal of Consulting and Clinical Psychology 61:354-359; Rudolph KD, Hammen C (1999) Age and gender as determinants of stress exposure, generation, and reactions in youngsters: A transactional perspective. Child Development 70:660-677). Higher values indicate greater levels of subjectively perceived family stress. Additional data are available for 107 parents who completed all 6 subscales of the Psychological Well-Being (PWB) Scale (Ryff CD (1989) Happiness is everything, or is it? Explorations on the meaning of psychological well-being. J. Pers Soc. Psychol 57: 1069-1081), resulting in scores for PWB_Total (average score across all 6 subscales) as well as scores for subscales measuring Purpose in Life (PWB_Purpose), Environmental Mastery (PWB_Environmental_Mastery), Self-Acceptance (PWB_Self_Accept), Autonomy (PWB_Autonomy), Personal Growth (PWB_Growth), Positive Relations with Others (PWB_Relationship). Higher scores indicate greater psychological well being. Also available for those individuals are measures of age (years), male gender (0/1), ethnic group (1=White, 2=Chinese, 3=Indian, 4=Other Asian, 5=Other Ethnicity), Body Mass Index (kg/m^2), heavy alcohol consumption history (0/1), smoking history (0/1), and abundance of 8 mRNA transcripts indicating the relative prevalence of major leukocyte subsets (CD3E, CD3D, CD19, CD4, CD8A, FCGR3A, NCAM1, CD14). key word: Risk prediction

Project description:This study explored how chronic stress influences the activity of signaling pathways that regulate inflammation in the human monocyte transcriptome. The sample consisted of 33 adults caring for a family member with glioblastoma, a terminal brain cancer, and 47 control subjects whose lives were free of major stressors. The subjects were assessed on four occasions across an eight-month period. Relative to controls, caregivers’ monocytes showed increased expression of genes bearing response elements for nuclear-factor kappa B, a key pro-inflammatory transcription factor in monocytes. Simultaneously, caregivers showed reduced expression of genes with response elements for the glucocorticoid receptor, a transcription factor that conveys anti-inflammatory signals to monocytes. These transcriptional disparities were not attributable to demographic or behavioral confounds. They also were not attributable to differences in diurnal cortisol output, or the abundance of glucocorticoid receptor expressed by monocytes. In ex vivo studies of monocytes stimulated with the bacterial product lipopolysaccharide, caregivers showed increased production of the pro-inflammatory cytokine interleukin-6, and were less sensitive to cortisol-mediated inhibition of this response. These findings suggest a scenario wherein chronic stressors engender functional changes that hamper monocytes’ capacity to transduce cortisol’s anti-inflammatory signals. These changes occur in parallel with, and perhaps enable, greater inflammatory signaling via nuclear-factor kappa B. The resulting inflammatory milieu could serve as a pathogenic mechanism through which chronic stressors like caregiving accentuate vulnerability to later health problems. series type: Risk prediction Individual differences in basal leukocyte gene expression profiles as a function of chronic caregiving stress Characteristics included in statistical analyses of gene expression data are provided in each sample records.
