Zebrafish as a model in Parkinson’s disease

April is Parkinson disease awareness month and for this reason, we decided to talk about zebrafish and this neurodegenerative disease. By their numerous advantages as a model organism, zebrafish show us one more time that they are relevant in neurotoxicity studies and neurodegenerative disorders. The prevalence of Parkinson disease has increased over the past 25 years (1) and for this reason, studies about the comprehension of this disease are really important to find an effective treatment.  Parkinson disease Zebrafish models of Parkinson's disease Conclusion References Parkinson disease Parkinson disease (PD)…

Do zebrafish fall in love?

Valentine's Day just passed and zebrafish show us their dance again. In fact, male zebrafish have a special way to seduce females: they court females by dancing!  By being an emergent model in biology and medicine, zebrafish are more and more studied and used. But do we really know about their social behavior? This article tries to better understand zebrafish breeding and mating choice in order to increase egg production in fish facilities and laboratories.  Zebrafish and its life cycle Mating choice The courtship Conclusion References Zebrafish and its life…

Xenopus laevis chromosomes in the Christmas spirit

Christmas is coming and even the African clawed frog (Xenopus laevis) cells are in the Christmas spirit. In fact their cells contain a structure that looks like Christmas trees. But what is this particular structure? They are rRNA transcription units in chromatin spreads. And what does this mean? Keep reading to understand it! In this article we will explain the genetic and transcription bases of this structure. DNA and RNA Christmas tree structure  Conclusion References DNA and RNA All living organisms are built from deoxyribonucleotide acid (DNA). In animals, most…

Where do our aquatic models come from ?

Did you know that the EggSorter works with small biological entities from different species: from zebrafish, medaka and killifish eggs to xenopus oocytes and embryos? Sounds cool, right? But do you know where these species exactly come from and what they are used for in research? This article presents the ecology of these organisms and gives a glimpse of how they are used in research. Zebrafish Medaka Killifish African clawed frog Conclusion References Zebrafish The zebrafish is used as a model organism in laboratories because they are easy to feed…
