Special Issue Information

Dear Colleagues,

Aquatic organisms are an irreplaceable source of medicinal drugs and therapeutics, a perfect model system and indicator for many human diseases, and often also a source of remedies for environmental pollutants. As an example, for several decades, the African clawed frog Xenopus laevis has been used for human pregnancy tests. Between the 1940s and 1960s, thousands of frogs were imported to the USA by pharmaceutical companies and injected with pregnant women’s urine. Xenopus frogs are the perfect human ciliary-based model for kidney disease, and the Xenopus sex reversal is an excellent indicator of water contamination with endocrine disruptors that mimic human sex hormones and are present in the majority of cosmetics and everyday products. Zebrafish and squid eyes are a model for human ocular diseases, such as glaucoma, cataracts, photoreceptor degeneration, and cornea and retina disorders. The Atlantic horseshoe crab’s (Limulus polyphemus) blue blood has been the source of limulus amebocyte lysate (LAL) and has been used to test the bacterial contamination of vaccines and medical equipment. Over the past 30 years, scientists have identified over 20,000 novel biochemical compounds from aquatic organisms, and dozens have been tested in clinical trials. Cytarabine and vidarabine isolated from Caribbean sponges are used to treat leukemia and lymphoma, and systematic herpes virus infections, respectively. Ziconotide, a powerful analgesic drug, is isolated from the cone snail, and trabectedin (Yondelis), a marine alkaloid isolated from the tunicate, is used to treat advanced soft-tissue sarcoma and ovarian cancer.

For this Special Issue, we invite research studies and review articles on the recent progress in aquatic organisms as a source of medication for human diseases. In addition, papers on environmental pollutant markers that act as sources of anti-pollutant compounds are also welcome.

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 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.

Benefits of Publishing in a Special Issue

Vision is fundamental to the acquisition of motor, cognitive, and social skills, playing a crucial role in typical development. Early visual impairments are associated with various neurodevelopmental conditions, including Autism Spectrum Disorder (ASD).

Vision is fundamental to the acquisition of motor, cognitive, and social skills, playing a crucial role in typical development. Early visual impairments are associated with various neurodevelopmental conditions, including Autism Spectrum Disorder (ASD). The (Brain-specific serine/threonine-protein kinase 2, BRSK2) gene has been identified as a high-risk gene for ASD. This study aims to investigate the role of brsk2 in retinal photoreceptor development and visual function in zebrafish. Using behavioral assays, histological analysis, and transcriptomic profiling, we assessed the impact of brsk2 deletion on retinal structure and function. The results showed that brsk2ab−/− zebrafish larvae exhibited significantly enhanced light perception compared to wild-type (WT) controls. Structural analysis of the retina revealed disruptions in the layered organization, along with up-regulated rhodopsin expression in retinal cells. Additionally, transcriptomic analysis indicated that key opsins and genes involved in visual development and phototransduction pathways were markedly up-regulated following brsk2 deletion. This research highlights the importance of brsk2 in early retinal circuit development and its potential implications for understanding sensory processing deficits in neurodevelopmental disorders. By linking BRSK2 to specific sensory phenotypes, this study addresses a critical gap in knowledge regarding the mechanisms underlying sensory abnormalities in ASD and related conditions. Full article
