DNA methylation profiles in adults born at extremely low birth weight / Karen J. MATHEWSON in Development and Psychopathology, 34-1 (February 2022)
[article]
Titre : DNA methylation profiles in adults born at extremely low birth weight Type de document : Texte imprimé et/ou numérique Auteurs : Karen J. MATHEWSON, Auteur ; Patrick O. MCGOWAN, Auteur ; Wilfred C. DE VEGA, Auteur ; Ryan J. VAN LIESHOUT, Auteur ; Katherine M. MORRISON, Auteur ; Saroj SAIGAL, Auteur ; Louis A. SCHMIDT, Auteur Article en page(s) : p.19-36 Langues : Anglais (eng) Mots-clés : DNA methylation profiling epigenetic modification extremely low birth weight (ELBW) sex differences stress reactivity and vulnerability Index. décimale : PER Périodiques Résumé : Effects of stresses associated with extremely preterm birth may be biologically ?recorded? in the genomes of individuals born preterm via changes in DNA methylation (DNAm) patterns. Genome-wide DNAm profiles were examined in buccal epithelial cells from 45 adults born at extremely low birth weight (ELBW; ?1000 g) in the oldest known cohort of prospectively followed ELBW survivors (Mage = 32.35 years, 17 male), and 47 normal birth weight (NBW; ?2500 g) control adults (Mage = 32.43 years, 20 male). Sex differences in DNAm profiles were found in both birth weight groups, but they were greatly enhanced in the ELBW group (77,895 loci) versus the NBW group (3,424 loci), suggesting synergistic effects of extreme prenatal adversity and sex on adult DNAm profiles. In men, DNAm profiles differed by birth weight group at 1,354 loci on 694 unique genes. Only two loci on two genes distinguished between ELBW and NBW women. Gene ontology (GO) and network analyses indicated that loci differentiating between ELBW and NBW men were abundant in genes within biological pathways related to neuronal development, synaptic transportation, metabolic regulation, and cellular regulation. Findings suggest increased sensitivity of males to long-term epigenetic effects of extremely preterm birth. Group differences are discussed in relation to particular gene functions.

This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (<1000 g) survivors (N = 179) and normal birth weight controls (N = 145) in the world, born between 1977 and 1982. Motor skills were measured using a performance-based assessment at age 8 and a retrospective self-report, and self-esteem was reported during three follow-up periods (age 12–16, age 22–26, and age 29–36). We found that birth weight status moderated the association between early motor skills and self-esteem. Stable over three decades, the self-esteem of normal birth weight participants was sensitive to early motor skills such that those with poorer motor functioning manifested lower self-esteem, while those with better motor skills manifested higher self-esteem. Conversely, differences in motor skill development did not affect the self-esteem from adolescence to adulthood in individuals born at extremely low birth weight. Early motor skill development may exert differential effects on self-esteem, depending on whether one is born at term or prematurely.

SCHMIDT, Auteur Article en page(s) : p.837-843 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Extremely low birth weight (ELBW; 5-HTTLPR). We followed the oldest longitudinal cohort of ELBW survivors to adulthood. Participants provided buccal cells and reported on internalizing problems, using the Young Adult Self-Report when they were in their mid-20s (ELBW/SGA, N = 28; ELBW/AGA, N = 60; NBW, N = 81) and mid-30s (ELBW/SGA, N = 27; ELBW/AGA, N = 58; NBW, N = 76). The findings indicate that ELBW/SGAs carrying the 5-HTTLPR short allele reported increased internalizing problems, particularly depression, during the third and fourth decades of life. This is the first known report on gene–environment interactions predicting psychopathology among ELBW survivors. Our findings elucidate putative neurobiological pathways that underlie risk for psychopathology.

VAN LIESHOUT, Auteur ; Khrista BOYLAN, Auteur Article en page(s) : p.876-890 Langues : Anglais (eng) Mots-clés : adolescents BPD frontal EEG asymmetry social rejection Index. décimale : PER Périodiques Résumé : Although associations among borderline personality disorder (BPD), social rejection, and frontal EEG alpha asymmetry scores (FAA, a neural correlate of emotion regulation and approach-withdrawal motivations) have been explored in different studies, relatively little work has examined these relations during adolescence in the same study. We examined whether FAA moderated the relation between BPD features and rejection sensitivity following a validated social exclusion paradigm, Cyberball. A mixed, clinical-community sample of 64 adolescents (females = 62.5%; Mage = 14.45 years; SD = 1.6; range = 11-17 years) completed psychodiagnostic interviews and a self-report measure of BPD (Time 1). Approximately two weeks later (Time 2), participants completed a resting EEG recording followed by Cyberball. FAA moderated the relation between BPD features and overall feelings of rejection following Cyberball: individuals with greater relative left FAA had the highest and lowest feelings of social rejection depending on whether they had high and low BPD feature scores, respectively. Results remained after controlling for age, sex, gender, depression, and BPD diagnosis. These results suggest that FAA may moderate the relation between BPD features and social rejection, and that left frontal brain activity at rest may be differentially associated with those feelings in BPD. Findings are discussed in terms of the link between left frontal brain activity in the regulation and dysregulation of social approach behaviors, characteristic of BPD.

VAN LIESHOUT, Auteur Article en page(s) : p.1421-1434 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Perinatal and later postnatal adversities have been shown to adversely affect socioeconomic trajectories, while enhanced early cognitive abilities improve them. However, little is known about the combined influence of these exposures on social mobility. In this study, we examined if childhood IQ moderated the association between four different types of postnatal adversity (childhood socioeconomic disadvantage, childhood sexual abuse, lifetime psychiatric disorder, and trait neuroticism) and annual earnings at 30–35 years of age in a sample of 88 extremely low birth weight survivors. Our results suggested that higher childhood IQ was associated with greater personal income at age 30–35. Extremely low birth weight survivors who did not face psychological adversities and who had higher childhood IQ reported higher income in adulthood. However, those who faced psychological adversity and had higher childhood IQ generally reported lower income in adulthood. Our findings suggest that cognitive reserve may not protect preterm survivors against the complex web of risk factors affecting their later socioeconomic attainment.
