Tobacco, nicotine, benzo(a)pyrene
Zhu J, et al. Transgenerational transmission of hyperactivity in a mouse model of ADHD. J Neurosci 2014;34:2768–73.
In a mouse model, grandpups of gestating dams exposed to nicotine exhibited behaviors comparable to ADHD.
Rehan VK, et al. Perinatal nicotine-induced transgenerational asthma. Am J Physiol Lung Cell Mol Physiol 2013;305:L501–7.

Maritz GS, et al. The effect of grand maternal nicotine exposure during gestation and lactation on lung integrity of the F2 generation. Pediatric. Pulmonol. 2014;49:1,67-75.
In a rat model, Grand‐maternal nicotine (F0) resulted in parenchymal deterioration and emphysema in the F2 progeny due to increased numbers of premature senescent cells together with a slower cell proliferation. The transfer of premature aging characteristics from the F1 progeny to the F2 progeny is via the male and female germ cell line.
Meier MJ, et al. In utero exposure to benzo[a]pyrene increases mutation burden in the soma and sperm of adult mice. Environ Health Perspect 2017;125:82–8.
In a mouse model, higher mutation rates were found in offspring sperm when the pregnant dam was exposed to the tobacco component BaP. Okay slightly off topic, but let’s not forget the importance of de novo mutagenesis in germ cells, which can be precipitated by exposure to mutagenic substances such as BaP. Now back to our program.
El-Sayed A, et al. The transgenerational impact of benzo(a)pyrene on murine male fertility. Human Reproduction 2010;25(10):2427–2433
In a mouse model, exposure to BaP decreases the fertilization potential of exposed males and has an adverse impact on sperm function and fertility in subsequent generations.
Esakky P, et al. Paternal exposure to cigarette smoke condensate leads to reproductive sequelae and developmental abnormalities in the offspring of mice. Reprod Toxicol. 2016;65:283-294.In a mouse model, cigarette smoke condensate exposure to the male caused DNA damage and cytotoxicity in testes via accumulation of benzo(a)pyrene (B[a]P) and cotinine. Decreased expression of growth arrest and DNA damage inducible alpha (Gadd45a), aryl hydrocarbon receptor (Ahr), and cyclin-dependent kinase inhibitor 1A (P21) was seen in CSC exposed testes. Apoptotic germ cell death was detected by induction of Fas, FasL, and activated caspase-3. The CSC-exposed males displayed reduction in sperm motility and fertilizing ability and sired pups with reduced body weight and crown-rump length, and smaller litter size with higher numbers of resorption.

In a mouse model, male mice were exposed to low-dose nicotine in their drinking water. They then bred these mice with females that had never been exposed to nicotine. While the fathers were behaviorally normal, both sexes of offspring displayed hyperactivity, attention deficit, and cognitive inflexibility. When female (but not male) mice from this generation were bred with nicotine-naïve mates, male offspring displayed fewer, but still significant, deficits in cognitive flexibility. Analysis of spermatozoa from the original nicotine-exposed males indicated that promoter regions of multiple genes had been epigenetically modified, including the dopamine D2 gene, critical for brain development and learning, suggesting that these modifications likely contributed to the cognitive deficits in the descendants.
Agents of general anesthesia and analgesics
Ju LS, et al. Role of epigenetic mechanisms in transmitting the effects of neonatal sevoflurane exposure to the next generation of male, but not female, rats, Brit J Anesth 2018.
In a rat model, neonatal exposure to the widely used general anesthetic agent sevoflurane can affect the brains and behavior of the next generation of males through epigenetic modification of Kcc2 expression, while F1 females are at diminished risk.
• Also See BJA editorial: Vutskits L, et al. A poisoned chalice: the heritage of parental anaesthesia exposure, Brit. J Anesth, 2018. (“Hence, we are faced with a real possibility that general anaesthetics are not innocuous agents that ‘only put children to sleep’ but rather formidable modulators of chromatin remodeling and function…. The current study extends previous reports of sex differences by showing that anaesthetic exposure itself can alter expression of chloride channels in certain brain regions and that this effect is heritable from exposed male parents to unexposed offspring.”)
Chalon J, et al. Exposure to halothane and enflurane affects learning function of murine progeny. Anesth Analg 1981;60:794–7.

Synthetic steroids—Diethylstilbestrol (DES)
Newbold RR, et al. Adverse Effects of the Model Environmental Estrogen Diethylstilbestrol Are Transmitted to Subsequent Generations. Endocrinology 2006;147(6):s11–s17,
"Interestingly, our data suggest that this increased susceptibility for tumors is passed on from the maternal lineage to subsequent generations of male and female descendants; the mechanisms involved in these transgenerational events include genetic and epigenetic events. Together, our data point out the unique sensitivity of the developing organism to endocrine-disrupting chemicals, the occurrence of long-term effects after developmental exposure, and the possibility for adverse effects to be transmitted to subsequent generations."

Anyway, MD, et al. Epigenetic Transgenerational Actions of Endocrine Disruptors and Male Fertility. Science 2005;308:1466-69.
In rat model, transient exposure of a gestating female during the period of gonadal sex determination to vinclozolin (an antiandrogenic compound) or methoxychlor (an estrogenic compound) induced an adult phenotype in the F1generation of decreased spermatogenic capacity (cell number and viability) and increased incidence of male infertility.

(Note: This is an F1 germ cell study, not an F2 phenotype study.) In a mouse model, the anti-cancer drug and topoisomerase II inhibitor etoposide was examined for effect on germ cells in the developing fetal ovary. Exposure of pre-follicular ovaries, in which topoisomerase IIα expression was germ cell-specific, resulted in a near-complete elimination of germ cells prior to follicle formation, with the remaining germ cells going on to form unhealthy follicles by the end of culture. In contrast, exposure to follicle-enclosed oocytes, which no longer expressed topoisomerase IIα in the germ cells, had no effect on total follicle numbers or health, the only effect seen specific to transitional follicles.

In a mouse model, males were exposed to six weeks of chronic stress before breeding. Offspring displayed significantly reduced HPA stress axis responsivity. Changes in transcription were seen in the brain, suggestive of epigenetic reprogramming and consistent with altered offspring stress responsivity, including increased expression of glucocorticoid-responsive genes in the PVN. In examining potential epigenetic mechanisms of germ cell transmission, robust changes in sperm microRNA were found.

In a mouse model, after males were exposed to chronic stress, sperm miRNAs were found postfertilization to alter offspring stress responsivity. Also zygote microinjection of the miRs, demonstrated a recapitulation of the offspring stress dysregulation phenotype.
Gapp, K. et al. Implication of sperm RNAs in transgenerational inheritance of the effects of early trauma in mice. Nat Neurosci 2014;17, 667–669.
In a mouse model, traumatic stress in early life altered mouse microRNA expression, and behavioral and metabolic responses in the progeny. Injection of sperm RNAs from traumatized males into fertilized wild-type oocytes reproduced the behavioral and metabolic alterations in the resulting offspring.
Franklin, TB, et al. Epigenetic transmission of the impact of early stress across generations. Biol Psychiatry 2010; 68, 408–15.
In a mouse model, mice were exposed to chronic and unpredictable maternal separation from postnatal day 1 to 14. Alterations in the profile of DNA methylation in the promoter of several candidate genes in the germline of the separated males were observed. Comparable changes in DNA methylation are also present in the brain of the offspring and are associated with altered gene expression.
Weiss, IC, et al. Inheritable effect of unpredictable maternal separation on behavioral responses in mice. Front Behav Neurosci 2011; 5,3.
In a mouse model, unpredictable maternal separation from birth to postnatal day 14 in C57Bl/6J mice has mild behavioral effects in the animals when adult, but that its combination with maternal stress exacerbates this effect. Further, the behavioral deficits are transmitted to the following generation through females, an effect that is independent of maternal care and is not affected by cross-fostering. The combined manipulation does not alter basic components of the hypothalamic–pituitary–adrenal axis but decreases the expression of the corticotropin releasing factor receptor 2 (CRFR2) in several nuclei of the amygdala and the hypothalamus in the brain of maternal-separated females.

In a mouse model, males subjected to postnatal traumatic stress have offspring with defects associated with impaired long-term memory. The expression in offspring of brain-specific signaling component in the hippocampus is reduced in the offspring, and DNA methylation at its promoter is altered both in the hippocampus of the offspring and the sperm of fathers.

In a mouse model, traumatic stress in postnatal life alters 5-HT1A receptor-evoked local and global functions in progeny of the exposed animals. Disrupted functional connectivity is consistent across generations and match limbic circuits implicated in mood disorders.
Golding J, et al. Grand-maternal smoking in pregnancy and grandchild’s autistic traits and diagnosed autism. Sci Rep 2017;7:46179.
This study of the ALSPAC cohort found significantly higher risk of autism and autism-related traits in the grandchildren of women who smoked cigarettes during pregnancy, through the exposed females.
Accordini S, et al. A three-generation study on the association of tobacco smoking with asthma, Int. J. Epidemiology 2018;dyy031, https://doi.org/10.1093/ije/dyy031
Based on data from the European Community Respiratory Health Survey III, fathers’ smoking before the age of 15 was associated with an increased risk of asthma without nasal allergies in their offspring, suggesting an effect of paternal pre-adolescent environment on the next generation. Grandmothers’ smoking during pregnancy was associated with an increased risk of asthma with nasal allergies in their grandchildren within the maternal line, suggesting a multi-generation effect of tobacco smoking.

Children had an increased risk of asthma in the first 6 years of life if their grandmothers smoked during early pregnancy, independent of maternal smoking. This exhibited a dose‐response relationship and was associated with a persistent childhood asthma phenotype.
Miller LL, et al. Do Grandmaternal Smoking Patterns Influence the Etiology of Childhood Asthma? Chest 2014;145(6)1213-1318.
In ALSPAC cohort, no association with asthma in relation to maternal prenatal exposure. Some evidence of an increase in asthma risk with paternal prenatal exposure when the study mother was a nonsmoker, a finding particularly strong for girls.
Tobacco impacts on germ cell integrity (selected)
Cheng SF, et al. Nicotine exposure impairs germ cell development in human fetal ovaries cultured in vitro. Aging 2018 Jul 12;10(7):1556-1574. Exposure to nicotine in vitro resulted in the marked increase of apoptosis in the ovaries in a time and dose-dependent manner. Evidence that adverse nicotine effects are potentially due to an increased level of reactive oxygen species (ROS) and consequent DNA damage, both in the ovarian somatic cells and germ cells, are reported.

This study of 47,450 women in the Nurses’ Health Study II found significantly elevated odds for ADHD in the grandchildren of women who took the toxic synthetic hormone drug DES (diethylstilbestrol) during pregnancy. [Yes, some studies I list in this response are new and I know Mitchell is not clairvoyant. Nevertheless they help paint the larger picture.]

(“If disorders like ADHD are epigenetic conditions [that is, dependent on or heavily modulated by discoverable epigenetic changes that are traceable to preventable environmental exposures], it would have powerful implications for where national research dollars should focus to find ways to reduce the incidence of ADHD and other mental disorders.”)
Tournaire M, et al. Birth defects in children of men exposed in utero to diethylstilbestrol (DES), Therapie, March 3, 2018.
The study suggests an increased incidence of two male genital tract defects in sons of men prenatally exposed to DES. This intergenerational effect had already been observed in animals and in the offspring of women prenatally exposed to DES.

Titus-Ernstoff L, et al. Birth defects in the sons and daughters of women who were exposed in utero to diethylstilbestrol (DES). Int J Androl 2010;33:377–84.
Data suggest a possible association between the mother’s prenatal DES exposure and birth defects in their offspring, particularly in daughters. We cannot, however, rule‐out the possible influence of reporting bias. In particular, the exposed daughters’ elevated risk of cardiac defects may be as a result of the underreporting of these conditions by unexposed mothers.

Shnorhavorian, M, et al. Differential DNA methylation regions in adult human sperm following adolescent chemotherapy: potential for epigenetic inheritance, PloS One 2017;12(2)journal.pone.0170085.
Adolescent chemotherapy exposure promoted epigenetic alterations that persisted approximately ten years after exposure. A signature of statistically significant DMRs was identified in the exposed males, found in CpG desert regions of primarily 1 kilobase size. This study did not investigate phenotypic outcomes in the next generation, but the topic, and suggestion of possible impairment of offspring, is of such tremendous social importance I felt the need to include it here.
