Special Issue Information

Dear Colleagues,

Jerry Heindel, on behalf of Healthy Environment and Endocrine Disruptor Strategies (www.HEEDS.org ) and Giancarlo Panzica on behalf of Italian Group for the Study of Neuromorphology (G.I.S.N., https://www.gisn.it ) propose to develop a Special Issue of Metabolism focused on the importance of Metabolism Disrupting Chemicals in metabolic disease.

Metabolic diseases, type 2 diabetes, liver diseases, and obesity are all increasing across the globe. They are multifactorial diseases that are controlled by many internal and external factors. The control of energy metabolism is a central event for the survival of an organism and the alterations that could lead to metabolic diseases. This control operates at two levels, in the periphery (e.g., liver, fat tissue, GI tract, pancreas, muscle and other organs) and the brain (e.g., the neuroendocrine hypothalamic system and other regions).

The focus of the metabolism field has been on genetics, diet, and exercise in the etiology of these diseases. We now know that some natural and synthetic chemicals present in the environment, named Metabolism Disrupting Chemicals (MDCs) or simply metabolism disruptors, can target the endocrine systems at the basis of the control of energy metabolism and therefore likely play an important role in causing metabolic diseases.

Publishing in a special issue with a focus on both original research and reviews on the role of MDCs in the etiology of metabolic diseases will improve the impact of the research.

The topics that can be covered in this Special Issue include but are not limited to:

Any aspect of metabolic diseases, type 2 diabetes, liver disease, or obesity with a focus on the role and/or mechanisms of MDCs.

Original research can focus on in vitro, computational, animal or human/epidemiology studies. Animal and human/epidemiology studies can focus on developmental or adult exposures in a single generation or across generations, single chemicals or mixtures of chemicals or the interaction of chemicals and nutrition. They can focus on developing data for new MDCs, the mechanism for a known or mixture of known MDCs.

Reviews can focus on the importance of MDCs in any metabolic diseases individually or in combination, or any subset of the research. For example, articles could focus on the hypothalamic control of metabolism, the importance of MDCs and the microbiome, the interaction between MDCs and nutrition, the role of exosomes in MDC action, importance of transgenerational inheritance of any of the metabolic diseases.

Manuscripts dealing with challenges/solutions to the acceptance of the role of MDCs in metabolic diseases by basic scientists, clinicians, regulators, and the public, as well as the challenges or research needed, for example, are highly desired.

Other topics may be acceptable. If in doubt, contact us.

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. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

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.

Cetyl Alcohol Polyethoxylates Disrupt Metabolic Health in Developmentally Exposed Zebrafish

Abstract
Alcohol polyethoxylates (AEOs), such as cetyl alcohol ethoxylates (CetAEOs), are high-production-volume surfactants used in laundry detergents, hard-surface cleaners, pesticide formulations, textile production, oils, paints, and other products. AEOs have been suggested as lower toxicity replacements for alkylphenol polyethoxylates (APEOs), such as the nonylphenol [...] Read more.
Alcohol polyethoxylates (AEOs), such as cetyl alcohol ethoxylates (CetAEOs), are high-production-volume surfactants used in laundry detergents, hard-surface cleaners, pesticide formulations, textile production, oils, paints, and other products. AEOs have been suggested as lower toxicity replacements for alkylphenol polyethoxylates (APEOs), such as the nonylphenol and octylphenol polyethoxylates. We previously demonstrated that nonylphenol polyethoxylates induced triglyceride accumulation in several in vitro adipogenesis models and promoted adiposity and increased body weights in developmentally exposed zebrafish. We also demonstrated that diverse APEOs and AEOs were able to increase triglyceride accumulation and/or pre-adipocyte proliferation in a murine pre-adipocyte model. As such, the goals of this study were to assess the potential of CetAEOs to promote adiposity and alter growth and/or development (toxicity, length, weight, behavior, energy expenditure) of developmentally exposed zebrafish (Danio rerio). We also sought to expand our understanding of ethoxylate chain-length dependent effects through interrogation of varying chain-length CetAEOs. We demonstrated consistent adipogenic effects in two separate human bone-marrow-derived mesenchymal stem cell models as well as murine pre-adipocytes. Immediately following chemical exposures in zebrafish, we reported disrupted neurodevelopment and aberrant behavior in light/dark activity testing, with medium chain-length CetAEO-exposed fish exhibiting hyperactivity across both light and dark phases. By day 30, we demonstrated that cetyl alcohol and CetAEOs disrupted adipose deposition in developmentally exposed zebrafish, despite no apparent impacts on standard length or gross body weight. This research suggests metabolic health concerns for these common environmental contaminants, suggesting further need to assess molecular mechanisms and better characterize environmental concentrations for human health risk assessments.

The prevalence of poor metabolic health is growing exponentially worldwide. This condition is associated with complex comorbidities that lead to a compromised quality of life. One of the contributing factors recently gaining attention is exposure to environmental chemicals, such as endocrine-disrupting chemicals (EDCs). Considerable evidence suggests that EDCs can alter the endocrine system through immunomodulation. More concerning, EDC exposure during the fetal development stage has prominent adverse effects later in life, which may pass on to subsequent generations. Although the mechanism of action for this phenomenon is mostly unexplored, recent reports implicate that non-coding RNAs, such as microRNAs (miRs), may play a vital role in this scenario. MiRs are significant contributors in post-transcriptional regulation of gene expression. Studies demonstrating the immunomodulation of EDCs via miRs in metabolic health or towards the Developmental Origins of Health and Disease (DOHaD) Hypothesis are still deficient. The aim of the current review was to focus on studies that demonstrate the impact of EDCs primarily on innate immunity and the potential role of miRs in metabolic health. Full article
