Special Issue Information

Dear Colleagues,

We announce a forthcoming Special Issue in the International Journal of Molecular Sciences (IJMS) entitled “Molecular Mechanisms and Therapeutic Strategies for Pregnancy Complications.” This Special Issue will gather high-quality original research articles, reviews, and perspectives that focus on molecular pathways, novel diagnostic biomarkers, and therapeutic strategies related to complications of pregnancy.

Pregnancy is a complex physiological process governed by finely tuned interplay between maternal and fetal systems. While most pregnancies proceed without significant issues, a considerable proportion is complicated by conditions that can jeopardize maternal and fetal health. These include pre-eclampsia, gestational diabetes mellitus, intrauterine growth restriction (IUGR), preterm birth, placental insufficiency, recurrent pregnancy loss, and infections such as chorioamnionitis. Despite advances in obstetric care, the underlying molecular and cellular mechanisms of many of these disorders remain incompletely understood, and effective targeted treatments are still lacking.

This Special Issue will provide a platform for disseminating innovative research that contributes to our understanding of the molecular and cellular basis of pregnancy-related disorders, as well as potential interventions. We welcome submissions that address, but are not limited to, the following themes:

  • Molecular and cellular mechanisms underlying pregnancy complications;
  • Epigenetic and genetic factors contributing to placental dysfunction;
  • Oxidative stress, inflammation, and immune dysregulation in pregnancy pathologies;
  • Biomarkers for early prediction, diagnosis, and monitoring of pregnancy complications;
  • Novel drug targets and pharmacological interventions;
  • Therapeutic strategies including nutraceuticals, gene therapy, and biologics;
  • Role of extracellular vesicles, microRNAs, and long non-coding RNAs;
  • Microbiome and its influence on pregnancy outcomes;
  • Maternal-fetal interactions and signaling pathways in normal and pathological pregnancies;
  • Systems biology and omics approaches (transcriptomics, metabolomics, proteomics)/

We also encourage submissions that present translational or clinical research findings, as well as in vitro, animal model, and computational studies that may lead to the development of innovative therapies or diagnostics.

The International Journal of Molecular Sciences (IJMS) is an international, peer-reviewed open-access journal published by MDPI, with an impact factor of 4.9. The journal provides rapid publication of high-quality scientific papers and has a broad readership in the fields of molecular biology, biochemistry, physiology, and medical sciences.

This Special Issue offers a unique opportunity to publish your work on a widely visible and indexed platform. All submitted manuscripts undergo rigorous peer review to ensure their high scientific standards and relevance to the scope of the Special Issue. Accepted papers will be published promptly and made freely available to the global scientific community.

Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

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 Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Porphyrins are intermediates in heme biosynthesis and have been proposed as biomarkers of metabolic dysfunction and environmental exposure in autism spectrum disorder (ASD). This study aimed to evaluate urinary porphyrin fractions and trace element ratios in children with ASD compared to neurotypical controls. Urinary porphyrins were quantified using high-performance liquid chromatography (HPLC), and trace elements were measured via inductively coupled plasma mass spectrometry (ICP-MS) normalized to urinary creatinine. Trace element ratios (e.g., Zn/Cu, Se/Pb) were calculated. Statistical comparisons were made using the Mann–Whitney U-test. Children with ASD showed significantly elevated urinary levels of coproporphyrin (median: 1.94 µg/g creatinine vs. 1.32 in controls; p = 0.02) and pentacarboxyporphyrin (0.86 vs. 0.57; p = 0.01), and reduced hexacarboxyporphyrin (0.12 vs. 0.23; p = 0.03). Lead (Pb) levels were significantly higher in ASD (median: 1.96 µg/g creatinine vs. 0.82; p = 0.004), while mercury (Hg) was not significantly different. Several trace element ratios differed significantly: Zn/Cu (ASD 41.9 vs. controls 49.1; p = 0.021), Se/Pb (12.9 vs. 25.7; p = 0.002), Cu/Se (0.49 vs. 0.38; p = 0.008), and Zn/Pb (19.5 vs. 44.8; p = 0.002). The Hg/Se ratio did not differ significantly.: Children with ASD demonstrate altered porphyrin profiles and trace element imbalances, including increased Pb and disrupted Zn/Cu and Se/Pb ratios, indicating oxidative stress and impaired detoxification. Combined assessment of porphyrins and trace element ratios may provide valuable non-invasive biomarkers for environmental and metabolic disturbances in ASD. Full article

Maternal nutrition and gut microbiome composition are central regulators of fetal development and perinatal outcomes, modulating immune signaling, oxidative balance, and epigenetic programming. The authors searched PubMed, Scopus, the Cochrane Library, and Web of Science for full-text, peer-reviewed articles published in English between 2010 and 2025, using keywords relevant to maternal diet, gut microbiome, epigenetic modifications, oxidative stress, reactive oxygen species (ROS), short-chain fatty acids (SCFAs), placental function, and perinatal outcomes. Selected studies provided detailed insights into how maternal dietary patterns and microbiome-derived metabolites influence placental function, fetal growth, and neonatal health. Integration of the microbiome, epigenetics, and nutritional factors reveals key molecular and metabolic networks that shape perinatal health. Targeted modulation of these networks provides a foundation for personalized strategies to improve neonatal outcomes. Full article
