Special Issue Information

Dear Colleagues,

In light of the great response that we received to our previous Special Issue, "Nitric Oxide (NO) and Hydrogen Sulfide (H2S) in Biology, Illness, and Therapies", we decided to revisit this topic.

Gaseous signaling molecules, including nitric oxide (NO), carbon dioxide (CO), and hydrogen sulfide (H2S), have been emerging as physiologically and pathophysiologically important mediators in mammals. Manipulating these mediators as a therapeutic measure appears promising in various diseases, and has already, at least partly, enhanced their clinical application, mostly through the inhalation of NO. The manipulation of H2S or persulfide/polysulfide, oxidative products of H2S, is being explored in clinical trials. However, these therapies still face challenges regarding broader clinical application, such as their toxicity, rapid diffusion, short half-life, and narrow therapeutic window. Novel therapeutic methods or strategies are required to enable more successful clinical applications for these gaseous mediators. These mediators or their metabolites also crosstalk/interact with each other and could exhibit nonspecific diverse reactions, which complicate our understanding of the biology of gaseous mediators and remain to be elucidated.

In this Special Issue, we welcome original research articles or review articles that focus on the physiology/pathophysiology, therapies, detection methods, and redox reactions related to NO, H2S, and their metabolites, facilitating the establishment of novel therapies for illnesses.

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. Antioxidants 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 2900 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.

Pregnant women with chronic kidney disease (CKD) face increased risks of adverse outcomes in their adult offspring. Offspring rats born to dams fed an adenine diet develop hypertension, coinciding with dysregulated hydrogen sulfide (H2S) and nitric oxide (NO) pathways, as well as alterations in gut microbiota. Chondroitin sulfate (CS) is a multifunctional food known for its diverse bioactivities. As a sulfate prebiotic, CS has shown therapeutic potential in various diseases. Here, we investigated the protective effects of maternal CS supplementation against hypertension in offspring induced by an adenine diet. Mother rats were administered regular chow, 0.5% adenine, 3% CS, or a combination throughout gestation and lactation. Maternal CS supplementation effectively protected offspring from hypertension induced by the adenine diet. These beneficial effects of CS were connected with increased renal mRNA and protein levels of 3-mercaptopyruvate sulfurtransferase, an enzyme involved in H2S production. Furthermore, maternal CS treatment significantly enhanced alpha diversity and altered beta diversity of gut microbiota in adult offspring. Specifically, perinatal CS treatment promoted the abundance of beneficial microbes such as Roseburia hominis and Ruminococcus gauvreauii. In conclusion, perinatal CS treatment mitigates offspring hypertension associated with maternal adenine diet, suggesting that early administration of sulfate prebiotics may hold preventive potential. These findings warrant further translational research to explore their clinical implications. Full article
