Abstract

BACKGROUND: Chronic physical aggression (CPA) is characterized by frequent use of physical aggression from early childhood to adolescence. Observed in approximately 5% of males, CPA is associated with early childhood adverse environments and long-term negative consequences. Alterations in DNA methylation, a covalent modification of DNA that regulates genome function, have been associated with early childhood adversity. AIMS: To test the hypothesis that a trajectory of chronic physical aggression during childhood is associated with a distinct DNA methylation profile during adulthood. METHODS: We analyzed genome-wide promoter DNA methylation profiles of T cells 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. Methylation profiles covering the promoter regions of 20 000 genes and 400 microRNAs were generated using MeDIP followed by hybridization to microarrays. RESULTS: In total, 448 distinct gene promoters were differentially methylated in CPA. Functionally, many of these genes have previously been shown to play a role in aggression and were enriched in biological pathways affected by behavior. Their locations in the genome tended to form clusters spanning millions of bases in the genome. CONCLUSIONS: This study provides evidence of clustered and genome-wide variation in promoter DNA methylation in young adults that associates with a history of chronic physical aggression from 6 to 15 years of age. However, longitudinal studies of methylation during early childhood will be necessary to determine if and how this methylation variation in T cells DNA plays a role in early development of chronic physical aggression.

  • A genome-wide study of men found that parental physical aggression in childhood and adolescence was associated with differential methylation in genes previously implicated in aggressive behavior.

    “A genome-wide study of men found that parental physical aggression in childhood and adolescence was associated with differential methylation in genes previously implicated in aggressive behavior [50].”

    From Biological Embedding of Early-Life Adversity and a Scoping Review of the Evidence for Intergenerational Epigenetic Transmission of Stress and Trauma in Humans (2023) · cites this paper as [50]

    The Methods describe a genome-wide methylation study of adult men assessed for their own physical aggression from ages 6 to 15; the Discussion reports differential methylation in genes previously linked to aggression. The paper does not study parental physical aggression, so that part of the claim is unsupported. The indexed passages provide section labels but no page numbers. (LLM, conf=0.90)

  • There were significant overrepresentations in chromosomes 4 and 5 (p = 0.01).

    “Significant overrepresentations in chromosomes 4 and 5 (p = 0.01).”

    From Genetics of child aggression, a systematic review (2024) · cites this paper as Provençal [126]

    The Results section (‘Methylation associated with chronic physical aggression clusters by genomic location’; page unavailable) reports a higher density of methylation differences on chromosomes 4 and 5. It does not report that the chromosome-wide overrepresentations were significant at p = 0.01; its separate finding of significant enrichment concerns six 500-kb regions. (LLM, conf=0.86)

  • The review found converging evidence for a role of AVPR1A in child aggression coming from genome-wide association, epigenomic, and candidate gene studies.

    “Nonetheless, we found converging evidence for a role of AVPR1A in child aggression coming from genome-wide association [35], epigenomic [126], and candidate gene [101] studies.”

  • Five genes previously linked with aggression were differentially methylated (AVPR1A, HTR1D, GRM5 less methylated in CPA group, DRD1, SLC6A3 more methylated in CPA group).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
