Special Issue Information

Dear Colleagues,

The expression of genes and their epigenetic modifications drive development throughout the life cycle from conception to death. Successful and desirable development depends on sequential changes in the expression of these genes owing, in part, to their healthy epigenetic modifications.  However, epigenetic changes resulting from adverse environments and aging also lead to the development of a variety of childhood and adult diseases and disorders. These pathological conditions reflect undesirable epigenetic landscapes and include diabetes, cardiovascular disease, cancer, Alzheimer’s disease and many others in humans. This Special Issue intends to (1) review and report recent and new research findings about epigenetic changes in genes that regulate the development of humans and other organisms, including all stages of ontogeny, and (2) consider age-related and other epigenetic changes that drive manifestations of pathological conditions. We invite manuscript submissions concerning, but not limited to, the following keywords regarding the genes and their modifications normally regulating development, their undesirable epigenetic modifications owing to aging and adverse environmental conditions, and the transgenerational transmission of such modified genes.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Environmental forces impacting public health include exposure to toxic substances, adverse childhood experiences (ACEs), diet, and exercise. Here, we examine the first two of these forces in some detail since they may be amenable to correction through cultural, medical, and practitioner intervention. At the same time, changing people’s dietary and exercise routines are likely more resistant to these interventions and are referred to only incidentally in this review. That is, societal efforts could prevent exposure to toxicants and ACEs—not necessarily requiring cooperation by the affected individuals—whereas changing diet and exercise practices requires an individual’s discipline. Toxic substances considered in this review include endocrine disruptors, arsenics, 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), the organic solvent, Trichloroethylene (TCE), and the Benzo[a]pyrene (B[a]P) produced from incomplete combustion of tobacco and other organic materials. Exposure to each of these toxic substances may have serious adverse health effects, especially in genetically more susceptible individuals. For example, children of mothers exposed to the endocrine disruptor, Atrazine, have significantly lower birth length, weight, and head circumference. Moreover, male offspring exhibit genital abnormalities, and all of these effects may be transgenerational. However, analyses of interactions among genes, the environment, and epigenetic modifications have already revealed distinctive individual risks of adverse reactions to toxic exposure. So, interventions through precision medicine might improve the health of those exposed individuals. Adults previously exposed to more than one ACE (e.g., child abuse and inter-parental violence) are more likely to develop anxiety, cancer, and diabetes. Detecting ACE exposures in children in the general population is fraught with difficulty. Thus, the risks of ACEs to our health remain even more insidious than exposures to toxicants. Nevertheless, higher provider compassion is associated with significantly better clinical outcomes for patients with these afflictions. For all these reasons, the first major aim of this review is to recount several of the major forces contributing to or impairing public health. Our second major aim is to examine mitigating influences on these forces, including social justice and provider compassion in the setting of precision medicine. Idealistically, these mitigators might eventually lead to the development of more cooperative and compassionate cultures and societies. Full article
