Early life adversity alters normal sex-dependent developmental dynamics of DNA methylation in rhesus monkeys

ABSTRACT: This study mapped the genome wide DNA methylation changes in CD3+ T lymphocytes from rhesus monkeys from postnatal day 14 through two years of age in both males and females and determined the impact of maternal deprivation on the DNA methylation profile. We show here that DNA methylation profiles evolve from birth to adolescence and are sex dependent. DNA methylation changes accompany imposed weaning, attenuating the difference between males and females.

Early life adversity alters normal sex-dependent developmental dynamics of DNA methylation in rhesus monkeys

Project description:This study mapped the genome wide DNA methylation changes in CD3+ T lymphocytes from rhesus monkeys from postnatal day 14 through two years of age in both males and females and determined the impact of maternal deprivation on the DNA methylation profile. We show here that DNA methylation profiles evolve from birth to adolescence and are sex dependent. DNA methylation changes accompany imposed weaning, attenuating the difference between males and females. Altogether 71 T cell DNA samples were used in 4 different groups (male control, male stress, female control, female stress) at 4 different developmental stage (1 month, before weaning at 6-7 months, after weaning at 9-10 months, and after 2 years at 26-30 months) having 3-6 samples per each group. The DNA samples were pooled in each group and then subjected to Whole Genome Amplification in triplicates.

Transcriptome profiling in five vitally important tissues of Cynomolgus monkeys using customized NimbleGen microarrays

Project description:Cynomolgus monkeys are well-established translational models for biomedical research and drug testing. To evaluate organ transcriptomes and gene expression variability in Cynomolgus monkeys, we used Customized NimbleGen Microarrays (Design ID: 120419_Cynomolgus_v5_TH_exp_HX12) for genome-wide gene expression profiling on 5 different tissues (heart, kidney, liver, lung, spleen) from 21 Cynomolgus monkeys. Cynomolgus monkey samples were derived from breeding centers located in the Philippines (3 females and 3 males), in Vietnam (2 females and 2 males), in China for animals from Mainland Southeast Asia (3 females), or in Mauritius (4 females and 4 males). Furthermore, genome-wide copy number variation was analyzed in tissue samples from the same animals using a custom NimbleGen 4.2 million probes comparative genomic hybridization (CGH) array to associate CNV genotypes with expression changes of proximal genes.

Genome-wide copy number variation profiling in Cynomolgus monkeys using customized NimbleGen CGH microarrays

Project description:Cynomolgus monkeys are well-established translational models for biomedical research and drug testing. Cynomolgus monkeys are outbred species and exhibit substantial levels of genetic variation which can affect the outcome and interpretation of biomedical studies. Copy number variations (CNVs) are a significant source of genetic diversity and a comprehensive understanding of the genomic impact of CNVs on phenotypic traits is limited. A custom 4.2 million probes comparative genomic hybridization (CGH) array (Design-ID: 120405_Cynomolgus5_CGH_UX1) has been designed on the basis of the Cynomolgus monkey genome (Ebeling et al. (2011) Genome Research; PMID: 21862625) to assess genome-wide copy number variation among Cynomolgus monkeys. Using Cynomolgus monkey specific NimbleGen CGH Microarrays we profiled the genomes of 21 Cynomolgus monkeys. Germline DNA from 21 Cynomolgus monkeys with different origin was tested against a Cynomolgus monkey reference. Cynomolus monkey samples were derived from breeding centers located in the Philippines (3 females and 3 males), in Vietnam (2 males and 2 females), in China for animals from Mainland Southeast Asia (3 females), or in Mauritius (4 females and 4 males). Furthermore genome-wide expression profiles were analyzed in 5 vitally important tissue samples (heart, kidney, liver, lung, spleen) from the same animals using a custom Cynomolgus monkey specific NimbleGen gene expression microarray (design ID: 120419_Cynomolgus_v5_TH_exp_HX12) to associate CNV genotypes with expression changes of proximal genes using a cis expression quantitative trait loci (cis-eQTL) mapping approach. Expression data have been deposited at the NCBI Gene Expression Omnibus (GEO) under accession numbers GSE76560. The array CGH results analyzed in this study are further described in Gschwind A.R. et al. (2016) "Diversity and regulatory impact of copy number variation in the primate Macaca fascicularis". under submission

DNA Methylation Signature of Childhood Chronic Physical Aggression in T Cells of Both Men and Women (Agilent)

Project description:High frequency of physical aggression is the central feature of severe conduct disorder and is associated with a wide range of social, mental and physical health problems. We have previously tested the hypothesis that differential DNA methylation signatures in peripheral T cells are associated with a chronic aggression trajectory in males. Despite the fact that sex differences appear to play a pivotal role in determining the development, magnitude and frequency of aggression, most of previous studies focused on males, so little is known about female chronic physical aggression. We therefore tested here whether or not there is a signature of physical aggression in female DNA methylation and, if there is, how it relates to the signature observed in males. Genome-wide promoter methylation profiles of T cell DNA from adult females on a Chronic Physical Aggression (CPA, n=5) trajectory during childhood and adolescence were compared to those on normative physical aggression trajectories (NPA, n=14). Two technical replicates were generated for each individual.

DNA Methylation Signature of Childhood Chronic Physical Aggression in T Cells of Both Men and Women (Illumina)

Project description:High frequency of physical aggression is the central feature of severe conduct disorder and is associated with a wide range of social, mental and physical health problems. We have previously tested the hypothesis that differential DNA methylation signatures in peripheral T cells are associated with a chronic aggression trajectory in males. Despite the fact that sex differences appear to play a pivotal role in determining the development, magnitude and frequency of aggression, most of previous studies focused on males, so little is known about female chronic physical aggression. We therefore tested here whether or not there is a signature of physical aggression in female DNA methylation and, if there is, how it relates to the signature observed in males. Genome-wide promoter methylation profiles of T cell DNA from adult males and females on a Chronic Physical Aggression (CPA) trajectory during childhood and adolescence were compared to adults on a normative physical aggression trajectories (NPA). Each sample was bisulphite converted gDNA pooled in equimolar amounts. Three different pools of genomic DNA were made per group: male CPA (2 or 3 different subjects per pool), male NPA (4 different subjects per pool), female CPA (2 different subjects per pool) and female NPA (4 or 5 different subjects per pool) . The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles of the 2 groups in both sex.

The X-chromosome dosage compensation program during the development of cynomolgus monkeys

Project description:X-chromosome dosage compensation ensures balanced gene dosage between the X chromosome and autosomes and between the sexes, involving divergent mechanisms among mammals. We elucidated a distinct mechanism for X-chromosome inactivation (XCI) in cynomolgus monkeys, a model for human development. The trophectoderm and cytotrophoblast acquire XCI around implantation through an active intermediate bearing repressive modifications and compacted structure, whereas the amnion, epiblast, and hypoblast maintain such an intermediate protractedly, attaining XCI by a week after implantation. Males achieve X-chromosome up-regulation (XCU) progressively, whereas females show XCU coincidentally with XCI, both establishing the X:autosome dosage compensation by 1 week after implantation. Conversely, primordial germ cells undergo X-chromosome reactivation by reversing the XCI pathway early during their development. Our findings establish a foundation for clarifying the dosage compensation mechanisms in primates, including humans.

Association of childhood chronic physical aggression with a DNA methylation signature in adult human T cells

Project description:Chronic physical aggression (CPA) is characterized by frequent use of physical aggression from early childhood to adolescence. Observed in approximately 5% of males, it is associated with early childhood adverse environments. DNA methylation, a covalent modification of DNA, regulates genome function and has been associated with early childhood adverse environments. We analyzed T cell DNA genome-wide promoter methylation profiles from two groups of adult males assessed annually for frequency of physical aggression between 6 and 15 years of age: a group with CPA and a control group. Whole genome methylation analysis was performed using MeDIP followed by hybridization to microarrays. We mapped the promoter regions of 20 000 genes and 400 microRNAs.

Fetal malformations and early embryonic gene expression response in Cynomolgus monkeys maternally exposed to thalidomide

Project description:EXPERIMENT: The animal experiments were performed at Shin Nippon Biomedical Laboratories (SNBL), Ltd. (Kagoshima, Japan) in compliance with the Guideline for Animal Experimentation (1987), and in accordance with the Law Concerning the Protection and Control of Animals (1973) and the Standards Relating to the Care and Management of Experimental Animals (1980). This study was approved by the Institutional Animal Care and Use Committee of SNBL and performed in accordance with the ethics criteria contained in the bylaws of the SNBL committee. Each female monkey was paired with a male of proven fertility for one day between day 11 and day 15 of the menstrual cycle. Pregnant females, aged 5-8 years and weighing 2.84-3.76 kg on day 22 of gestation, were allocated randomly to two groups, each with three monkeys, and housed individually. The monkeys were orally dosed with (Â±)-thalidomide (Lot no. SDH7273/SDJ3347, Wako Pure Chemical Industries, Ltd., Osaka, Japan) at 0 or 20 mg/kg by oral intubation on day 26 of gestation, which was during the critical period for thalidomide-induced teratogenesis [Delahunt and Lassen, 1964; Hendrickx, 1973]. Dosage was adjusted to the body weight on day 22 of gestation and the drug was packed in a gelatin capsule. Control monkeys received the capsule only. ANIMAL MODEL: Macaca fascicularis INTERVAL: NON.
