Descrição do Curso 

----------------------------------------   REGISTRATION DEADLINE EXTENDED UNTIL 8th OF JULY  -----------------------------------------

 

Bone disorders affect millions of people worldwide and current treatments have a limited efficacy often accompanied by side effects. The discovery of novel bone anabolic compounds with either pharmaceutical or nutraceutical value is thus needed. The zebrafish has recently emerged as a model for human bone diseases but also as a system for the screening of compounds that would treat or prevent these diseases. Beyond the technical advantages over traditional models (e.g. rodents), the high similarity of targets, physiology, drug metabolism and pharmacology in comparison to humans further highlights the potential of zebrafish as a robust model for drug screenings. The BIOSKEL lab (CCMAR, University of Algarve) has developed several zebrafish assays to evaluate the osteogenic potential of natural or synthetic compounds. Within the scope of the training workshop here presented, we propose to share both the theoretical and practical knowledge required to go through all the steps of those procedures. 

Main topics:

  • Basis of zebrafish biology and husbandry
  • Current knowledge on drug screenings
  • Ways of exposing zebrafish to experimental compounds
  • Imaging of bone structures and morphometric analysis
  • Assessment of compound osteogenic and regenerative potential
Formato 

Zebrafish tools presented in this workshop are the basis of a first-line medium throughput screening methodology.

In the drug discovery pipeline, first line screenings represent a critical filter to reduce the amount of compounds to be further tested and are therefore time and money savers. Until recently, in vitro cell systems or in vivo rodent systems were commonly used, although several bottlenecks existed (e.g. a cell line cannot represent the complexity of a whole organism, rodents are slow growers, expensive to maintain and have an intra-uterine early development). However, in vivo zebrafish systems overcome those obstacles and have emerged as a promising alternative to the traditional systems.   

This workshop will provide both conceptual and experimental know-how on zebrafish screening systems through lectures given by experts in the field. Attendees will also have the opportunity to acquire some technical expertise through hands-on sessions where they will learn to manipulate zebrafish tools toward the screening of osteoactives. 

Pré-requisitos 

Basic formation in biology, biomedical sciences or biochemistry. Knowledge of basic molecular biology techniques is necessary to understand some concepts.

IMPORTANT: Participants are asked to bring their own computers to perform the image analysis and morphometric assessments. If possible ImageJ should be previously installed (available for free at https://imagej.net)
