Comments on 'Significance of developmental expression of amphioxus Branchiostoma belcheri and zebrafish Danio rerio Hsd17b10 in biological and medical research'.

Abstract

The reported data on the developmental expression of Hsd17b10 gene in Danio rerio is crucial to the utilization of the D. rerio embryo as an animal model for human developmental disorders caused either by mutations on HSD17B10 (formerly HADH2) or by defective expression of the gene. Related diseases were summarized, and it was noticed that hyperinsulinaemic hypoglycaemia is not linked to HSD17B10. This inherited disease is actually caused by a deletion in the HADH gene on chromosome 4. Moreover, it was found by a revision of the reported phylogenetic tree that hydroxyacyl-CoA dehydrogenase II or rather hydroxysteroid (17beta) dehydrogenase 10 (HSD10) of amphioxus Branchiostoma belcheri-occupies a transition position from HSD10 orthologs of invertebrates to those of vertebrates.
