Oxidative Stress Responses to Marine Toxins: From Molecular Mechanisms to Ecological Impacts

Dear Colleagues,

Acute or chronic exposure to environmental pollutants, such as blooms associated with the production of marine toxins, may produce a number of alterations within aquatic organisms. Although they can tolerate a certain number of short-term pollutant-induced biological disturbances, long-term exposure can deplete repair and defense mechanisms, causing a negative impact on cell organization, known as oxidative stress.

Oxidative stress is an important component of the biological response of marine organisms when exposed to a wide variety of environmental stressors on different scales of time and space. Therefore, oxidative stress is produced when the rate of production of reactive oxygen species (ROS) exceeds the rate of elimination produced by endogenous antioxidant molecules. Thus, this imbalance that leads to the production and accumulation of ROS causes damage to lipids, proteins and the DNA of cells of aquatic organisms. The damage can be determined depending on the species, age, organ, type of exposure, type of material, duration of the dose and external environmental factors.

We invite you to submit your latest research findings or a review article to this Special Issue, entitled: “Oxidative Stress Responses to Marine Toxins: From Molecular Mechanisms to Ecological Impacts”.

We look forward to your contribution.

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.
