This article reviews the history of the zebrafish, and discusses the scenarios when other fish species are advantageous.
Mutations in the STXBP1 gene are implicated in childhood epilepsies and several neurodevelopmental disorders, however, nearly half of the STXBP1 variants recorded in the ClinVar database are Variants of Unknown Significance (VUS). In a recent publication, members of the InVivo Biosystems team discussed their work creating humanized C. elegans that expressed STXBP1 in order to classify variants as benign or pathogenic.
Rising healthcare costs mean it’s time for pharmaceutical companies to use non-mammalian models in their drug development process — by saving time and money pharmaceutical companies can make a return on their products without sky-high prices for consumers.
Using the models provided by InVivo Biosystems, the Starr & Luxton Labs were able to focus their efforts on understanding and evaluating the variants and complete their project in a timely manner.
In the age of industries continuously creating and remodeling chemicals, having a reliable way to test their toxicity is vital. At the same time, across all areas of research, there is the desire to shift away from traditional animal models. In this article we outline the New Approach Methods (NAMs) and some of the steps being taken to implement them.
The Undiagnosed Diseases Network UND is a nationwide network that is working to understand and diagnose rare and undiagnosed human diseases. The UND coordinates between research and clinical experts, using the latest genetic and genomic technologies to create a more personalized medicine model.
COVID-19 has broadly impacted biomedical research, in this article we give an overview of its effect on labs and discuss how this can shine a light on the advantages of using alternative model organisms in research.
The Undiagnosed Diseases Network brings together experts across the USA, combining clinical care and research to find diagnoses for undiagnosed patients. Zebrafish are extremely valuable disease models in this research, as they reduce the cost and speed up the process of identifying therapeutic targets. In this blog we highlight one rare disease whose mechanism was successfully identified using zebrafish.
Using Humanization we can take advantage of the ancient biology between humans and other organisms to create stand-ins – patient avatars – for drug screening studies. In this blog, we will focus on models of inborn errors of metabolism (IEM), as these genetic conditions can lead to hypersensitivity to the metabolite. Since stressor condition hypersensitivity can be used to detect favorable drug effects, IEM model systems are ideal tools for phenotypic screens to find molecules that alleviate the metabolic stress occurring from the deficiency. We discuss the model organisms used in hypersensitivity screens, and why they are advantageous to drug discovery. Ultimately, showcasing this approach’s potential to be widely generalized to many genetic disorders.
A common saying in science is that, “good science and good animal welfare go hand in hand.” In this article we provide an overview of the 3Rs (Replacement, Reduction and Refinement: guiding principles for the humane use of animals in research), look specifically at the UK’s well-documented implementation of them, and discuss how new techniques and technologies can continue to improve animal welfare.
