Lifestyle and genetic background are well known risk factors of cardiovascular disease (CVD). A third contributing factor is suboptimal fetal development, due to nutrient or oxygen deprivation, placental insufficiency, or exposure to toxic substances. The fetus adapts to adverse intrauterine conditions to ensure survival; the immediate consequence is low birth weight (LBW) and the long-term effect is an increased susceptibility to develop CVD in adult life. This process is known as Developmental Origins of Health and Disease (DOHaD) or fetal programming of CVD...

Exposure to environmental stressors during susceptible windows of development can result in negative health outcomes later in life, a concept known as the Developmental Origins of Health and Disease (DOHaD). There is a growing body of evidence that exposures to metals early in life (in utero and postnatal) increase the risk of developing adult diseases such as cancer, cardiovascular disease, non-alcoholic fatty liver disease, and diabetes. Of particular concern is exposure to the metalloid arsenic, a drinking water contaminant and worldwide health concern...

Metabolic syndrome (MetS) is a highly prevalent complex trait despite recent advances in pathophysiology and pharmacological treatment. MetS can begin in early life by so-called the developmental origins of health and disease (DOHaD). The DOHaD concept offers a novel approach to prevent MetS through reprogramming. High fructose (HF) intake has been associated with increased risk of MetS. HF diet becomes one of the most commonly used animal model to induce MetS. This review discusses the maternal HF diet induced programming process and reprogramming strategy to prevent MetS of developmental origin, with an emphasis on: (1) an overview of metabolic effects of fructose consumption on MetS; (2) insight from maternal HF animal models on MetS-related phenotypes; (3) impact of HF consumption induces organ-specific transcriptome changes; and (4) application of reprogramming strategy to prevent maternal HF consumption-induced MetS...

OBJECTIVES: The developmental origins of health and disease paradigm (DOHaD) is a concept that fetal environmental factors affect adult phenotypes. We performed experiments to evaluate the DOHaD theory in developmental disorders using mouse models. METHODS: In vitro fertilization and embryo transfer techniques were used for mouse production. The AIN93G-control diet, which contains 20% protein (CD), 5% protein-restricted diet (PR), and PR with supplemental folic acid (FA) were provided as experimental diets to mothers...

The brain and mind are not only determined genetically but are also nurtured by environmental stimuli in early life. However, the relationship between early life environment and phenotypes in adulthood remains elusive. Using the IntelliCage-based competition task for group-housed mice, we previously found that maternal exposure to a low dose of an environmental pollutant, dioxin, resulted in abnormal social behavior, that is, low competitive dominance, which is defined by decreased occupancy of limited resource sites under highly competitive circumstances...

In Japan, the prevalence of low birth weight (< 2,500 g) has been increasing, probably owing to leanness, exposure to toxic chemicals and smoking. Epidemiological studies revealed that low birth weight poses risks of hypertension, coronary heart diseases and diabetes. Although the precise mechanism has not been understood, there is an urgent need for appropriate public health interventions. MicroRNA (miRNA) is a small RNA consisting of approximately 22 nucleotides and distributed in a wide variety of organs and body fluids...

X-chromosome inactivation (XCI) occurs during the gestation period to compensate for the dosage of X-linked genes in female mammals. Xist RNA is a long noncoding RNA with a global epigenetic function and is indispensable for XCI from the initiation to establishment and maintenance phases. The X chromosome contains over 1,000 genes that are essential for proper development, especially that of the brain, immune system, metabolism and reproductive functions. We found that exposure to bisphenol A or folate deficiency during the fetal period changes the expressions of Xist, Tsix (the antisense repressor of Xist), and many X chromosome linked genes widely in newborn mice...

Evidence in support of the Developmental Origins of Health and Disease (DOHaD) hypothesis has reached the level where it can appropriately be used to inform practice. DOHaD informed interventions supporting primary noncommunicable disease risk reduction should target the pre- and periconceptional periods, pregnancy, lactation, childhood and adolescence. Such interventions are dependent on a health workforce (including dietitians, nurses, midwives, doctors, and nutrition teachers), that has a deep understanding of DOHaD concepts...

The growing field of 'Developmental Origin of Health and Disease' (DOHaD) generally reflects environmental influences from mother to child. The importance of maternal lifestyle, diet and other environmental exposures before and during gestation period is well recognized. However, few epidemiological designs explore potential influences from the paternal environment on offspring health. This is surprising given that numerous animal models have provided evidence that the paternal environment plays a role in a non-genetic inheritance of pre-conceptional exposures through the male germ line...

Paternal environment can induce detrimental developmental origins of health and disease (DOHaD) effects in resulting offspring and even future descendants. Such paternal-induced DOHaD effects might originate from alterations in a possible seminal fluid microbiome (SFM) and composite metabolome. Seminal vesicles secrete a slightly basic product enriched with fructose and other carbohydrates, providing an ideal habitat for microorganisms. Past studies confirm the existence of a SFM that is influenced by genetic and nutritional status...

Low- and middle-income countries (LMICs), particularly those in sub-Saharan Africa, are experiencing rapid increases in the prevalence of non-communicable diseases (NCDs), which may not be fully explained by urbanization and associated traditional risk factors such as tobacco smoking, excessive alcohol consumption, poor diet or physical inactivity. In this commentary, we draw attention to the concept of Developmental Origins of Health and Disease (DOHaD), where environmental insults in early life can contribute to long-term risk of NCDs, the impact of which would be particularly important in LMICs where poverty, malnutrition, poor sanitation and infections are still prevalent...

BACKGROUND: The placenta is the central regulator of maternal and fetal interactions. Perturbations of placental structure and function have been associated with adverse neurodevelopmental outcomes later in life. Placental CpG methylation represents an epigenetic modification with the potential to impact placental function, fetal development and child health later in life. STUDY DESIGN: Genome-wide placental CpG methylation levels were compared between spontaneous versus indicated deliveries from extremely preterm births (EPTBs) (n = 84)...

A variety of experimental and epidemiological studies lend support to the Developmental Origin of Health and Disease (DOHaD) concept. Yet, the actual mechanisms accounting for mid- and long-term effects of early-life exposures remain unclear. Epigenetic alterations such as changes in DNA methylation, histone modifications and the expression of certain RNAs have been suggested as possible mediators of long-term health effects of environmental stressors. This report captures discussions and conclusions debated during the last Prenatal Programming and Toxicity meeting held in Japan...

DEHP is a plasticizer which has been used in plastic products of everyday use for decades. Studies in mice and murine cell culture models identified DEHP as an endocrine disruptor that may also act as an obesogen. As this is of high concern in respect of the worldwide obesity epidemic, our aim is the translation of these findings into a human model system. On the basis of DOHaD, we investigated the influence of an environmentally relevant dose of DEHP [50 µg/ml] on adipogenesis in the human cell culture model SGBS...

Early stages of mammalian embryonic development are now known to be very sensitive to their microenvironment, with long term effects on fetal, postnatal, and adult health, thus extending to these early stages the concept of Developmental Origin of Health and Disease (DoHaD). In this scientific context, and with 3% of births in developed countries, safety of Assisted Reproductive Techniques procedures becomes a matter of concern. Besides, embryo technologies in domestic mammals, using huge number of embryos, do not seem to evidence heavy impacts on adult phenotypes...

Manganese is an essential trace element, but also at high levels a neurotoxicant. Manganese neurotoxicity has been extensively studied since its discovery in highly exposed workers. The International conference MANGANESE2016 held at the Icahn School of Medicine at Mount Sinai in New York provided relevant updates on manganese research in relation to both occupational and environmental exposures. Epidemiological, toxicological and cellular studies reported at the conference have yielded new insights on mechanisms of manganese toxicity and on opportunities for preventive intervention...

The incidence of metabolic disorders like type 2 diabetes (T2D) and obesity continue to increase. While it is evident that the increasing incidence of diabetes confers a global societal and economic burden, the mechanisms responsible for the increased incidence of T2D are not well understood. Extensive efforts to understand the association of early life perturbations with later onset of metabolic diseases, the founding principle of DOHaD, have been crucial in determining the mechanisms that may be driving the pathogenesis of T2D...

Developmental plasticity, a phenomenon of importance in both evolutionary biology and human studies of the developmental origins of health and disease (DOHaD), enables organisms to respond to their environment based on previous experience without changes to the underlying nucleotide sequence. Although such phenotypic responses should theoretically improve an organism's fitness and performance in its future environment, this is not always the case. Herein, we first discuss epigenetics as an adaptive mechanism of developmental plasticity and use signaling theory to provide an evolutionary context for DOHaD phenomena within a generation...
