An investigation of child maltreatment and epigenetic mechanisms of mental and physical health risk / Dante CICCHETTI in Development and Psychopathology, 28-4 pt2 (November 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-4 pt2 (November 2016) . - p.1305-1317 Titre : An investigation of child maltreatment and epigenetic mechanisms of mental and physical health risk Type de document : Texte imprimé et/ou numérique Auteurs : Dante CICCHETTI, Auteur ; Susan HETZEL, Auteur ; Fred A. ROGOSCH, Auteur ; Elizabeth D. HANDLEY, Auteur ; Sheree L. TOTH, Auteur Article en page(s) : p.1305-1317 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In the present investigation, differential methylation analyses of the whole genome were conducted among a sample of 548 school-aged low-income children (47.8% female, 67.7% Black, M age = 9.40 years), 54.4% of whom had a history of child maltreatment. In the context of a summer research camp, DNA samples via saliva were obtained. Using GenomeStudio, Methylation Module, and the Illumina Custom Model, differential methylation analyses revealed a pattern of greater methylation at low methylation sites (n = 197 sites) and medium methylation sites (n = 730 sites) and less methylation at high methylation sites (n = 907 sites) among maltreated children. The mean difference in methylation between the maltreated and nonmaltreated children was 6.2%. The relative risk of maltreatment with known disease biomarkers was also investigated using GenoGo MetaCore Software. A large number of network objects previously associated with mental health, cancer, cardiovascular systems, and immune functioning were identified evidencing differential methylation among maltreated and nonmaltreated children. Site-specific analyses were also conducted for aldehyde dehydrogenase 2 (ALDH2), ankyrin repeat and kinase domain containing 1 (ANKK1), and nuclear receptor subfamily 3, group C, member 1 (NR3C1) genes, and the results highlight the importance of considering gender and the developmental timing of maltreatment. For ALDH2, the results indicated that maltreated girls evidenced significantly lower methylation compared to nonmaltreated girls, and maltreated boys evidenced significantly higher methylation compared to nonmaltreated boys. Moreover, early onset–not recently maltreated boys evidenced significantly higher methylation at ALDH2 compared to nonmaltreated boys. Similarly, children with early onset–nonrecent maltreatment evidenced significantly higher methylation compared to nonmaltreated children at ANKK1. The site-specific results were not altered by controlling for genotypic variation of respective genes. The findings demonstrate increased risk for adverse physical and mental health outcomes associated with differences in methylation in maltreated children and indicate differences among maltreated children related to developmental timing of maltreatment and gender in genes involved in mental health functioning.

Genome-wide DNA methylation in 1-year-old infants of mothers with major depressive disorder / Dante CICCHETTI in Development and Psychopathology, 28-4 pt2 (November 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-4 pt2 (November 2016) . - p.1413-1419 Titre : Genome-wide DNA methylation in 1-year-old infants of mothers with major depressive disorder Type de document : Texte imprimé et/ou numérique Auteurs : Dante CICCHETTI, Auteur ; Susan HETZEL, Auteur ; Fred A. ROGOSCH, Auteur ; Elizabeth D. HANDLEY, Auteur ; Sheree L. TOTH, Auteur Article en page(s) : p.1413-1419 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A genome-wide methylation study was conducted among a sample of 114 infants (M age = 13.2 months, SD = 1.08) of low-income urban women with (n = 73) and without (n = 41) major depressive disorder. The Illumina HumanMethylation450 BeadChip array with a GenomeStudio Methylation Module and Illumina Custom model were used to conduct differential methylation analyses. Using the 5.0 × 10–7p value, 2,119 loci were found to be significantly different between infants of depressed and nondepressed mothers. Infants of depressed mothers had greater methylation at low methylation sites (0%–29%) compared to infants of nondepressed mothers. At high levels of methylation (70%–100%), the infants of depressed mothers were predominantly hypomethylated. The mean difference in methylation between the infants of depressed and infants of nondepressed mothers was 5.23%. Disease by biomarker analyses were also conducted using GeneGo MetaCore Software. The results indicated significant cancer-related differences in biomarker networks such as prostatic neoplasms, ovarian and breast neoplasms, and colonic neoplasms. The results of a process networks analysis indicated significant differences in process networks associated with neuronal development and central nervous system functioning, as well as cardiac development between infants of depressed and nondepressed mothers. These findings indicate that early in development, infants of mothers with major depressive disorder evince epigenetic differences relative to infants of well mothers that suggest risk for later adverse health outcomes.

Moderation of maltreatment effects on childhood borderline personality symptoms by gender and oxytocin receptor and FK506 binding protein 5 genes / Dante CICCHETTI in Development and Psychopathology, 26-3 (August 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-3 (August 2014) . - p.831-849 Titre : Moderation of maltreatment effects on childhood borderline personality symptoms by gender and oxytocin receptor and FK506 binding protein 5 genes Type de document : Texte imprimé et/ou numérique Auteurs : Dante CICCHETTI, Auteur ; Fred A. ROGOSCH, Auteur ; Kathryn F. HECHT, Auteur ; Nicki R. CRICK, Auteur ; Susan HETZEL, Auteur Article en page(s) : p.831-849 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In this investigation, gene–environment–gender interaction effects in predicting child borderline personality disorder symptomatology among maltreated and nonmaltreated low-income children (N = 1,051) were examined. In the context of a summer research camp, adult-, peer-, and self-report assessments of borderline precursor indicators were obtained, as well as child self-report on the Borderline Personality Features Scale for Children. Genetic variants of the oxytocin receptor genotype and the FK506 binding protein 5 gene CATT haplotype were investigated. Children who self-reported high levels of borderline personality symptomatology were differentiated by adults, peers, and additional self-report on indicators of emotional instability, conflictual relationships with peers and adults, preoccupied attachment, and indicators of self-harm and suicidal ideation. Maltreated children also were more likely to evince many of these difficulties relative to nonmaltreated children. A series of analyses of covariance, controlling for age and ancestrally informative markers, indicated significant Maltreatment × Gene × Gender three-way interactions. Consideration of the maltreatment parameters of subtype, onset, and recency expanded understanding of variation among maltreated children. The three-way interaction effects demonstrated differential patterns among girls and boys. Among girls, the gene–environment interaction was more consistent with a diathesis-stress model, whereas among boys a differential-sensitivity interaction effect was indicated. Moreover, the genetic variants associated with greater risk for higher borderline symptomatology, dependent on maltreatment experiences, were opposite in girls compared to boys. The findings have important implications for understanding variability in early predictors of borderline personality pathology.
