Special Issue Information

Dear Colleagues,

Animal models have played a critical role in understanding the pathogenesis and mechanisms of several diseases that are prevalent in animals and humans. They have played a critical role in developing pharmacological interventions that can treat diseases and thereby help in promoting health in animals and humans. Animal models from multiple species can be classified broadly as spontaneous models and models that are induced to imitate the signs and symptoms of diseases. Generally, whether they are spontaneous or developed, they should mimic the pathology and clinical signs of the disease that is being investigated. Although animal models have provided invaluable information related to the pathogenesis and mechanisms of disease, they sometimes fail to recapitulate complex interactions between multiple organ systems and tissues in the body. This results in difficulty comparing them for addressing specific disease conditions. This Special Issue of the International Journal of Molecular Sciences presents various animal models of human diseases of multiple organ systems and their advantages and disadvantages in using them for studying these diseases. This will be an invaluable resource for investigators who are interested in investigating specific diseases using animal models.

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. 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

  • 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.

During the 70 years since the Balkan endemic nephropathy was recognised, failure to make a universal diagnostic cause continues for some critical researchers. Claims for cause by toxic molecules from microorganisms and/or plants are difficult to verify experimentally in retrospect, partly because no lifetime human experimentation is possible and partly since no experimental source is a convincing model. Apoptosis as a primary step in human nuclear decline has been a source of experiments for many years. Now, one has been used, which employs the detection of abnormal nuclear hydroxyls by using an Abcam histology protocol. Recent access to a few human tissues diagnosed for the Balkan nephropathy has enabled preliminary exploration to publish some positive human manifestations of apoptosis. Parallel use and positive findings have also now illustrated applications to experimental rats’ kidneys after daily dietary exposure to ochratoxin A in lifetime experiments. Focus on renal cortical nephrons and their nuclei reveals a TUNEL-stained pattern with intensity linked to many months of the sub-clinical ochratoxin dietary exposure. The pattern survives long after exposure, but where experimental rats have internally developed cancer did not arise outside the kidney. Our experimental rat findings could not attribute the mechanism for the very different human urothelial tumours to traces of dietary ochratoxin A, but the present study encourages the exploration of more archived Balkan nephropathy renal cases to predict the focal urothelial origin of early tumours.
