Transmission of reduced levels of miR-34/449 from sperm to preimplantation embryos is a key step in the transgenerational epigenetic inheritance of the effects of paternal chronic social instability stress. Epigenetics 2024; 19:2346694. [PMID: 38739481 PMCID: PMC11093028 DOI: 10.1080/15592294.2024.2346694] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 04/09/2024] [Indexed: 05/16/2024] Open
Abstract
The transgenerational effects of exposing male mice to chronic social instability (CSI) stress are associated with decreased sperm levels of multiple members of the miR-34/449 family that persist after their mating through preimplantation embryo (PIE) development. Here we demonstrate the importance of these miRNA changes by showing that restoring miR-34c levels in PIEs derived from CSI stressed males prevents elevated anxiety and defective sociability normally found specifically in their adult female offspring. It also restores, at least partially, levels of sperm miR-34/449 normally reduced in their male offspring who transmit these sex-specific traits to their offspring. Strikingly, these experiments also revealed that inducing miR-34c levels in PIEs enhances the expression of its own gene and that of miR-449 in these cells. The same induction of embryo miR-34/449 gene expression likely occurs after sperm-derived miR-34c is introduced into oocytes upon fertilization. Thus, suppression of this miRNA amplification system when sperm miR-34c levels are reduced in CSI stressed mice can explain how a comparable fold-suppression of miR-34/449 levels can be found in PIEs derived from them, despite sperm containing ~50-fold lower levels of these miRNAs than those already present in PIEs. We previously found that men exposed to early life trauma also display reduced sperm levels of miR-34/449. And here we show that miR-34c can also increase the expression of its own gene, and that of miR-449 in human embryonic stem cells, suggesting that human PIEs derived from men with low sperm miR-34/449 levels may also contain this potentially harmful defect.

Abstract
Experiencing adverse childhood experiences (ACEs) may impact personal opinions, attitudes, and judgments, which can further result in HIV-related stigma. HIV-related stigma consequentially may impact HIV preventive measures such as HIV testing, pre-exposure prophylaxis uptake, and condom use. The extent to which ACEs influence HIV-related stigma perception has not been well studied. Therefore, the study aimed to examine the association between ACEs and perceived and interpersonal HIV-related stigma among Tanzanian HIV-negative men. Quantitative survey data were obtained from the Tanzania STEP (Self-Testing Education and Promotion) project established in four wards: Mabibo, Manzese, Tandale, and Mwanyanamala. A total of 507 men responded to the ACEs and HIV-related stigma questionnaires. ACEs were operationalized as types of ACEs (environmental, physical/psychological, sexual abuse) and ACE score (0 (reference) vs. 1, 2, 3, ≥ 4). Perceived HIV-related stigma was analyzed both as a binary (HIV stigma vs. no HIV stigma) and a continuous variable. Unadjusted and adjusted multinomial logistic and linear regression models were used to assess the associations between ACEs and HIV-related stigma. ACE types were associated with HIV stigma (b = 0.237, 95% CI [0.122-0.352], p = < .0001). Findings of the adjusted multinomial logistic regression model show that experiencing one ACE (aOR = 1.9; p-value = 0.023), two ACEs (aOR = 1.8; p-value = 0.044), four or more ACEs (aOR = 4.1; p-value = < 0.0001) were associated with greater perceived HIV-related stigma. Moreover, experiencing environmental (aOR = 8.6; p-value = 0.005), physical/psychological (aOR = 2.5; p-value = 0.004), and sexual abuse (aOR = 3.4; p-value = < 0.0001) were associated with higher odds of HIV-related stigma. Our study findings suggest that those who experience childhood trauma are more likely to have a higher perception of HIV-related stigma. Intervention programs targeting HIV stigma should consider addressing ACEs entailing the behavioral and psychological impact of childhood trauma.

Abstract
An understanding of the prevalence and risk factors of parental mental health problems is important for early intervention and prevention measures and shaping services for parents and their children. However, large representative surveys of parental mental health problems and associated risk factors are lacking. The aim of this study was to estimate prevalence rates of parental mental health problems using a standardised measure of psychiatric morbidity (General Health Questionnaire; GHQ-12), in a representative sample of parents and caregivers of children and young people (2-19 years) in Northern Ireland. Further, this study explored associated risk factors of parental mental health problems. A random household survey of parents and children was conducted between June 2019 and March 2020. Parental responses on demographic, economic, familial and psychological measures were collected (N = 2815) and 22% of parents and caregivers screened positive for mental health problems. The STROBE checklist for observational research was adhered to. Multivariate logistic regression indicated that being in receipt of benefits, having poor family support, a history of adverse childhood experiences, a history of exposure to politically motivated violence (the Troubles), and a child with conduct problems and poor health were all independent risk factors of increased parental mental health problems. Findings will help to inform future commissioning and development of services and broaden understanding of the correlates of parental mental health problems.

Mother adversity and co-residence time impact mother-child similarity in genome-wide and gene-specific methylation profiles. Clin Epigenetics 2024; 16:44. [PMID: 38509601 PMCID: PMC10953278 DOI: 10.1186/s13148-024-01655-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 03/08/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND The effects of adverse life events on physical and psychological health, with DNA methylation (DNAm) as a critical underlying mechanism, have been extensively studied. However, the epigenetic resemblance between mother and child in the context of neglectful caregiving, and whether it may be shaped by the emotional impact of maternal stressful events and the duration of co-residence (indexed by child age), remains unknown. The present study examined mother-child similarity in methylation profiles, considering the potential effect of mother adversity, mother empathy, neglect-control group, child age (an index of years of mother-child co-residence), and mother age. Using Illumina Epic arrays, we quantified DNAm in 115 mother-child saliva samples. We obtained a methylation similarity index by computing correlation coefficients between methylation profiles within dyads, for the entire epigenome, and five specific genes related to stress and empathy: NR3C1, FKPB5, OXTR, SCL6A4, and BDNF. RESULTS The methylation profiles of the mother-child familial pairs significantly correlated as compared to mother-child random pairs for the entire epigenome and NR3C1, FKBP5, OXTR and BDNF genes. Next, multiple linear regression models observed associations of mother adversity, child age, and neglect-control group on mother-child methylation similarity, only significant in mother-child familial pairs, after correcting for multiple comparisons. Higher mother adversity was associated with lower mother-child methylation similarity for the epigenome-wide analysis, for the BDNF gene, and in the neglect-control group for the OXTR gene. In turn, being an older child (longer co-residence) was associated with higher mother-child methylation similarity. CONCLUSIONS Mother adversity and co-residence time are modulating factors in the intergenerational methylation process that offer a window into development-dependent adaptations that can be affected by both hereditary and environmental factors, significantly observed only in biological dyads. A twofold implication for child well-being emerges, one is positive in that children of mothers exposed to life adversity or neglect did not necessarily inherit their methylation patterns. The other is concerning due to the influence of time spent living together, which affects similarity with the mother and potentially increases the risk of inheriting an epigenetic profile associated with future dysfunctional parenting patterns. This underscores the importance of the 'the earlier, the better' recommendation by the Child Protection System, which is not always followed.

Effect of parental adverse childhood experiences on intergenerational DNA methylation signatures from peripheral blood mononuclear cells and buccal mucosa. Transl Psychiatry 2024; 14:89.

Abstract
In this study, the effect of cumulative ACEs experienced on human maternal DNA methylation (DNAm) was estimated while accounting for interaction with domains of ACEs in prenatal peripheral blood mononuclear cell samples from the Maternal and Developmental Risks from Environmental Stressors (MADRES) pregnancy cohort. The intergenerational transmission of ACE-associated DNAm was also explored used paired maternal (N = 120) and neonatal cord blood (N = 69) samples. Replication in buccal samples was explored in the Children's Health Study (CHS) among adult parental (N = 31) and pediatric (N = 114) samples. We used a four-level categorical indicator variable for ACEs exposure: none (0 ACEs), low (1-3 ACEs), moderate (4-6 ACEs), and high (>6 ACEs). Effects of ACEs on maternal DNAm (N = 240) were estimated using linear models. To evaluate evidence for intergenerational transmission, mediation analysis (N = 60 mother-child pairs) was used. Analysis of maternal samples displayed some shared but mostly distinct effects of ACEs on DNAm across low, moderate, and high ACEs categories. CLCN7 and PTPRN2 was associated with maternal DNAm in the low ACE group and this association replicated in the CHS. CLCN7 was also nominally significant in the gene expression correlation analysis among maternal profiles (N = 35), along with 11 other genes. ACE-associated methylation was observed in maternal and neonatal profiles in the COMT promoter region, with some evidence of mediation by maternal COMT methylation. Specific genomic loci exhibited mutually exclusive maternal ACE effects on DNAm in either maternal or neonatal population. There is some evidence for an intergenerational effect of ACEs, supported by shared DNAm signatures in the COMT gene across maternal-neonatal paired samples.

Abstract
Indigenous individuals in Canada disproportionally experience higher rates of substance use concerns. This study examined clinical practices currently implemented with Indigenous-led residential treatment facilities to simultaneously address substance use and post-traumatic stress. A systematic review of relevant literature retrieved published approaches to address these concurrent disorders with Indigenous individuals. This review retrieved 35 sources related to trauma and substance use treatment among Indigenous individuals or communities. Among these sources, all leveraged cultural approaches as a dual treatment for trauma symptoms and substance use. Inconsistent results were reported among those sources (n = 3) who analyzed comparisons with wait-list controls or used randomized-controlled designs. Using culture-as-treatment was elaborated upon in the second goal of this study: an environmental scan of Indigenous-led treatment programs and qualitative interviews with 10 treatment center staff to understand how programs may address both substance use and traumatic symptoms among Indigenous-led substance use treatment centers across Canada. When we searched the websites of these centers, we found that approximately 38% (16 of 43) of treatment centers discussed implementing some form of treatment that addressed trauma symptoms in conjunction with primary substance use. Among the 10 staff participants, all discussed how trauma can impede client success in treatment, and ACE-specific programming is useful within their respective treatment programs. Results showed that when manualized treatments are used, they must be adapted to meet the specific needs of Indigenous communities, and culture-as-treatment is a popular approach among Indigenous-led treatment centers, particularly for addressing trauma symptoms.

Abstract
Chronically stressing male mice can alter the behavior of their offspring across generations. This effect is thought to be mediated by stress-induced changes in the content of specific sperm miRNAs that modify embryo development after their delivery to oocytes at fertilization. A major problem with this hypothesis is that the levels of mouse sperm miRNAs are much lower than those present in preimplantation embryos. This makes it unclear how embryos could be significantly impacted without an amplification system to magnify changes in sperm miRNA content, like those present in lower organisms where transgenerational epigenetic inheritance is well established. Here, we describe such a system for Chronic Social Instability (CSI) stress that can explain how it reduces the levels of the miR-34b,c/449a,b family of miRNAs not only in sperm of exposed males but also in preimplantation embryos ( PIEs ) derived from their mating, as well as in sperm of male offspring. Sperm-derived miR-34c normally positively regulates expression of its own gene and that of miR-449 in PIEs. This feed forward, auto-amplification process is suppressed when CSI stress reduces sperm miR-34c levels. Its suppression is important for the transmission of traits to offspring because restoring miR-34c levels in PIEs from CSI stressed males, which also restores levels of miR-449 in them, suppresses elements of elevated anxiety and defective sociability normally found specifically in their female offspring, as well as reduced sperm miR-34 and miR-449 levels normally found in male offspring, who pass on these traits to their offspring. We previously published that the content of sperm miR-34/449 is also reduced in men raised in highly abusive and/or dysfunctional families. We show here that a similar miRNA auto-amplification system functions in human embryonic stem cells. This raises the possibility that PIEs in offspring of these men also display reduced levels of miR-34/449, enhancing the potential translational significance of these studies.

Abstract
A large body of empirical research has demonstrated that caregiver adverse childhood experiences (ACEs) predict ACEs in one's child, a phenomenon known as the intergenerational transmission of ACEs. Little of this empirical research, however, has focused specifically on Indigenous peoples despite a growing body of theoretical literature and the wisdom of Elders and Traditional Knowledge Keepers that speaks to the presence of this phenomenon within Indigenous communities as well as the protective role of Indigenous cultural identity in preventing the intergenerational transmission of ACEs. The purpose of the current study was to conduct an empirical evaluation of this hypothesis, specifically that Indigenous cultural identity and social support protects against the intergenerational transmission of ACEs among Indigenous peoples and their children in the USA. Participants were 106 Indigenous women caregivers of children ages 10 to 14 in South Dakota who completed surveys. Results showed that Indigenous cultural identity moderated the association between caregiver ACEs and child ACEs. At high levels of cultural identity, there was no association between caregiver ACEs and child ACEs. At low levels of Indigenous cultural identity, however, there was a strong and positive relationship between caregiver ACEs and child ACEs. Social support did not moderate the association between caregiver ACEs and child ACEs. These findings underscore the need for initiatives that enhance Indigenous cultural identity and social support among Indigenous caregivers to prevent the intergenerational transmission of ACEs.

Abstract
OBJECTIVE The link between adverse childhood experiences (ACEs) and negative mental health outcomes is well established. However, the intergenerational link between caregiver ACE history and their child's psychosocial outcomes is understudied, particularly within minoritized groups. This study aimed to delineate relations between caregiver ACE exposure and their child's depression and posttraumatic stress disorder (PTSD) symptoms by proposing a serial mediation of caregiver PTSD, family management problems, and child ACEs. METHOD Two hundred seventy-three caregiver (Mage = 39.27; 88% female) and adolescent (Mage = 14.26; 57% female) dyads from low-income urban communities completed electronic questionnaires measuring PTSD symptoms and ACEs. Child participants also completed a measure of depression and family management problems. Regression and serial mediation analyses were conducted to examine associations among these variables. RESULTS Caregiver ACEs were significantly associated with their child's PTSD symptoms but were not related to their child's depression scores. Serial mediation analyses indicated that child ACEs mediated the relation between caregiver ACEs and their child's PTSD symptoms. Evidence for an overall indirect effect via caregiver PTSD, family management problems, and child ACEs was not found. No indirect effects between caregiver ACEs and child depression were found. CONCLUSIONS Findings demonstrate that higher levels of caregiver ACE exposure are associated with their child's PTSD symptoms in a sample of African American dyads living in urban, high-burden communities. These results suggest a need for ACE screening during medical visits and provides guidance for future clinical interventions. The distinct intergenerational consequences for caregivers with ACEs and their children's psychosocial wellbeing warrant further study. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Adverse Childhood Experiences (ACEs) are events that occur before a child turns 18 years old that may cause trauma. In this study, the effect of cumulative ACEs experienced on human maternal DNA methylation (DNAm) was estimated while accounting for interaction with domains of ACEs in prenatal peripheral blood mononuclear cell samples from the Maternal and Developmental Risks from Environmental Stressors (MADRES) pregnancy cohort. The intergenerational transmission of ACE-associated DNAm was also explored used paired maternal and neonatal cord blood samples. Replication in buccal samples was explored in the Children's Health Study (CHS). We used a four-level categorical indicator variable for ACEs exposure: none (0 ACEs), low (1-3 ACEs), moderate (4-6 ACEs), and high (> 6 ACEs). Effects of ACEs on maternal DNAm (N = 240) were estimated using linear models. To evaluate evidence for intergenerational transmission, mediation analysis was used. Analysis of maternal samples displayed some shared but mostly distinct effects of ACEs on DNAm across low, moderate, and high ACEs categories. CLCN7 and PTPRN2 was associated with maternal DNAm in the low ACE group and this association replicated in the CHS. ACE-associated methylation was observed in maternal and neonatal profiles in the COMT promoter region, with some evidence of mediation by maternal COMT methylation. Specific genomic loci exhibited mutually exclusive maternal ACE effects on DNAm in either maternal or neonatal population. There is some evidence for an intergenerational effect of ACEs, supported by shared DNAm signatures in the COMT gene across maternal-neonatal paired samples.

Abstract
The purpose of the present study was to examine intergenerational transmission of adverse childhood experiences (ACEs) from parents to children and examine the buffering influence of forgiveness of oneself and others. Participants were 150 parents and children enrolled in Head Start in an upper midwestern, rural state who volunteered to complete questionnaires measuring ACEs and levels of forgiveness of oneself and others. Multiple correlation and regression were used to examine the associations between parent-reported parent and child ACEs and self-forgiveness and forgiveness of others. Analyses revealed that parental ACEs and child ACEs were positively correlated. Parents with low and medium levels of self-forgiveness and forgiveness of others had a stronger positive correlation between their own experience of ACEs and their child's, whereas, for parents with high levels of self-forgiveness and forgiveness of others, the correlation between parent and child ACEs was reduced statistically to zero. The cycle of intergenerational transmission of ACEs may be interrupted, or at very least notably buffered, by forgiving oneself and others.

Abstract
Studies of DNA methylation have revealed the biological mechanisms by which life adversity confers risk for later physical and mental health problems. What remains unknown is the “biologically embedding” of maternal adverse experiences resulting in maladaptive parenting and whether these epigenetic effects are transmitted to the next generation. This study focuses on neglectful mothering indexed by a severe disregard for the basic and psychological needs of the child. Using the Illumina Human Methylation EPIC BeadChip in saliva samples, we identified genes with differentially methylated regions (DMRs) in those mothers with (n = 51), versus those without (n = 87), neglectful behavior that present similar DMRs patterns in their children being neglected versus non-neglected (n = 40 vs. 75). Mothers reported the emotional intensity of adverse life events. After covariate adjustment and multiple testing corrections, we identified 69 DMRs in the mother epigenome and 42 DMRs in the child epigenome that were simultaneously above the α = 0.01 threshold. The common set of nine DMRs contained genes related to childhood adversity, neonatal and infant diabetes, child neurobehavioral development and other health problems such as obesity, hypertension, cancer, posttraumatic stress, and the Alzheimer’s disease; four of the genes were associated with maternal life adversity. Identifying a shared epigenetic signature of neglect linked to maternal life adversity is an essential step in breaking the intergenerational transmission of one of the most common forms of childhood maltreatment.
