Hermetia illucens for Replacing Fishmeal in Aquafeeds: Effects on Fish Growth Performance, Intestinal Morphology, and Gene Expression in the Zebrafish (Danio rerio) Model

Antioxidant and immune gene expression in zebra fish (Danio rerio)

Iodine is the main ingredient produced by the thyroid hormone, which playa a central role in the metabolism and the immune system. The present study aims to evaluate the effects of feeding Artemia fransiscana enriched with potassium iodide on antioxidant and immune gene expression in zebra fish (Danio rerio). Zebra larvae with an average weight of 2±0.01 mg were randomly distributed into 4 trea...

Evaluation of of the performance of the zebrafish (Danio rerio) model in nanotoxicology studies with emphasis on embryo pathology

The present study was conducted to evaluate the performance of zebrafish (Danio rerio) as a model in embryo and fetal pathology in nanotoxicology studies. Examination of the sources showed that it is possible to completely inhibit hatching and fetal death when exposed to nanoparticles, because nanoparticles interact with hatching enzymes. Zebrafish embryo developmental abnormalities have been s...

Tilapia chromosomal growth hormone gene expression accelerates growth in transgenic zebrafish (Danio rerio)

Primary intestinal and vertebral chordomas in laboratory zebrafish (Danio rerio).

Chordomas are uncommon neoplasms arising from notochord remnants, most commonly occurring in the axial skeleton. Extraskeletal soft tissue chordomas are rare primary tumors, and primary alimentary tract chordomas have not been reported. Herein we report 24 cases of spontaneous primary intestinal chordomas in zebrafish, as well as 9 spontaneous vertebral chordomas. Both intestinal and vertebral ...

Danio Rerio, the Zebrafish

The zebrafish has long been a favourite model for the study of vertebrate development. Here we provide an overview of the current state of knowledge and resources for the study of this fish, with comments on the future direction of zebrafish genomics from Professor Mark Fishman and Dr Stephen Wilson.
