Early parental deprivation during primate infancy has a lifelong impact on gene expression in the male marmoset brain

ABSTRACT: Adverse early life experiences are well-established risk factors for neurological disorders later in life. However, the molecular mechanisms underlying the impact of adverse experiences on neurophysiological systems throughout life remain incompletely understood. Previous studies suggest that social attachment to parents in early development are indispensable for infants to grow into healthy adults. In situations where multiple offspring are born in a single birth in common marmosets, human hand-rearing is employed to ensure the survival of the offspring in captivity. However, hand-reared marmosets often exhibit behavioral abnormalities, including abnormal vocalizations, excessive attachment to the caretaker, and aggressive behavior. In this study, comprehensive transcriptome analyses were conducted on hippocampus tissues, a neuroanatomical region sensitive to social attachment, obtained from human hand-reared (N = 6) and parent-reared male marmosets (N = 5) at distinct developmental stages. Our analyses revealed consistent alterations in a subset of genes, including those related to neurodevelopmental diseases, across different developmental stages, indicating their continuous susceptibility to the effects of early parental deprivation. These findings highlight the dynamic nature of gene expression in response to early life experiences and suggest that the impact of early parental deprivation on gene expression may vary across different stages of development.

The Biological Embedding of Early Life Socioeconomic and Family Adversity in Children’s Genome-wide DNA Methylation

Project description:Early life social experiences are believed to confer persistent effects on individual’s biology and subsequent functioning and health. Using a diverse, longitudinal community sample of 178 children, we show that three different types of early life social experience: family income, parental education, and family psychosocial adversity, each predict DNA methylation within buccal epithelial cells. Each predictor was significantly associated with DNA methylation within a unique set of genomic CpG sites, with income showing the greatest number of associations. Findings were independently verified using pyrosequencing. Our results provide evidence for longitudinal associations between early life social environment and variation in DNA methylation during childhood, after adjusting for genetic ancestry and self-reported ethnic minority status. Gene ontology analyses of top, differentially methylated CpG sites point to genes serving immune and developmental regulation functions, suggesting potential pathways for the biological embedding of early life stress and its association with later development and health.

The effect of Repeated Cross Fostering (RCF) on transcriptomic profiles of mouse Ventral Tegmental Areas across different sexes and strains

Project description:Early life experiences affecting the attachment bond formation can result in maladaptive behaviors acting on developmental trajectories and programming adult brain functions in a sex-dependent manner. Repeated Cross Fostering (RCF) manipulation in mice is able to interfere with attachment bond formation in mice. Using males and females from two different inbred strains of mouse, known to respond very differently to the RCF, we analyzed the effect of RCF on the ventral tegmental area (VTA)-transcriptome in a sex-specific manner. Through next-generation mRNA-Seq, we profiled VTA transcriptomes in RCF and control adult male and female mice from both backgrounds.

Transcriptional response to early life stress in male and female mouse brain

Project description:This study explored the interaction of early life and adult stress on transcriptional and chromosomal states in a 2x2 design. Male and female mice were subjected to early life stress (ELS) or were standard-reared (Std), were housed normally through adolescence, and were then exposed to 10 days of control (Ctl) or chronic social defeat stress (CSDS: males only) or 3 days of sub-threshold variable stress (STVS: females only) conditions in adulthood. Long-lasting transcriptional alterations were assessed in the ventral tegmental area (VTA), nucleus accumbens (NAc), medial prefrontal cortex (PFC), and ventral hippocampus (HIP, males only) in adulthood.

DNA methylation signatures of parental deprivation in peripheral tissues of male rhesus macaques

Project description:This study mapped the genome wide DNA methylation changes in whole blood and buccal swab samples of 2 year old male rhesus monkeys subjected to parental deprivation in their first months of life (surrogate peer-reared condition). Equal numbers of control mother-reared (MR) and surrogate peer-reared (SPR) male monkeys whole blood (5 vs 5) and buccal swab samples (3 vs 3) were analyzed by methylated DNA immunoprecipitation (MeDIP) coupled with promoter tiling arrays.

Stress dynamically regulates co-expression networks of glucocorticoid receptor-dependent MDD and SCZ risk genes.

Project description:Early-life adversity is an important risk factor for major depressive disorder (MDD) and schizophrenia (SCZ) that interacts with genetic factors to confer disease risk through mechanisms that are still insufficiently understood. One downstream effect of early-life adversity is the activation of glucocorticoid receptor (GR)-dependent gene networks that drive acute and long-term adaptive behavioral and cellular responses to stress. We have previously shown that genetic variants that moderate GR-induced gene transcription (GR-response eSNPs) are significantly enriched among risk variants from genome-wide association studies (GWASs) for MDD and SCZ. Here, we show that the 63 transcripts regulated by these disease-associated functional genetic variants form a tight glucocorticoid-responsive co-expression network (termed GCN). We hypothesized that changes in the correlation structure of this GCN may contribute to early-life adversity-associated disease risk. Therefore, we analyzed the effects of different qualities of social support and stress throughout life on GCN formation across distinct brain regions using a translational mouse model. We observed that different qualities of social experience substantially affect GCN structure in a highly brain region-specific manner. GCN changes were predominantly found in two functionally interconnected regions, the ventral hippocampus and the hypothalamus, two brain regions previously shown to be of relevance for the stress response, as well as psychiatric disorders. Overall, our results support the hypothesis that a subset of genetic variants may contribute to risk for MDD and SCZ by altering circuit-level effects of early and adult social experiences on GCN formation and structure.

R. microplus expression profiles of larvae pre-attachment and feeding adult female stages in B. indicus and B. taurus

Project description:Comparative microarray analysis of Rhipicephalus (Boophilus) microplus expression profiles of larvae pre-attachment and feeding adult female stages on Bos indicus and B. taurus cattle Global analysis of gene expression changes in R. microplus during larval, pre-attachment and early adult stages of its life cycle feeding on Bos indicus and Bos taurus cattle were compared using gene expression microarray analysis. Among the 13 601 R. microplus transcripts from BmiGI Version 2 we identified 297 up and 17 down regulated transcripts were differentially expressed between R. microplus feeding on tick resistant cattle [Bos indicus (Brahman)] compared to R. microplus feeding on tick susceptible cattle [Bos taurus (Holstein-Friesian)]. These include genes encoding enzymes involved in primary metabolism, and genes related to stress, defence, cell wall modification, cellular signaling, receptor and cuticle. Microarrays were validated by qRT-PCR analysis of selected transcripts including the validation of three housekeeping genes. The analysis of all tick stages under survey suggested a coordinated regulation of defence proteins, proteases, and protease inhibitors to achieve successful attachment and survival of R. microplus on different host breeds particularly Bos indicus cattle. The microarray was conducted by NimbleGen Systems Inc following the method reported by Saldivar [Saldivar L et al., Insect Mol Biol 2008, 17(6):597-606]. 10 samples: 2 larva, 2 pre-attachment larva in B. indicus and 2 in B. taurus, and 2 adult ticks in B. indicus and 2 in B. taurus
