Homeobox genes in the Australian lungfish,Neoceratodus forsteri

Journal of Experimental Zoology, 1999
The aim of the present study was to determine whether the postulated gnathostome duplication from four to eight Hox clusters occurred before or after the split between the actinopterygian and sarcopterygian fish by characterizing Hox genes from the sarcopterygian lungfish, Neoceratodus forsteri.

Deiodinase type III in the Australian lungfish, Neoceratodus forsteri

General and Comparative Endocrinology, 2004
This work presents characterisation of deiodinase type III (D3) mRNA as cDNA and the tissue distribution of D3 mRNA in the Australian lungfish, Neoceratodus forsteri. We have identified the full length of a approximately 1.4 kb D3 mRNA in the liver, which has a single in-frame UGA codon and a selenocysteine insertion sequence (SECIS) form 2 in the 3 ...

Teleost-Type Angiotensin Is Present in Australian Lungfish,Neoceratodus forsteri

General and Comparative Endocrinology, 1999
Angiotensin I (ANG I) was produced from the incubation of lungfish plasma with homologous kidney extracts. The purified peptide was found to have the sequence of H-Asn-Arg-Val-Tyr-Val-His-Pro-Phe-Thr-Leu-OH, which is homologous for the first eight residues with all teleost angiotensins so far sequenced, although lungfish generally possess tetrapod-type

In VitroBiosynthesis of Androgens in the Australian Lungfish,Neoceratodus forsteri

General and Comparative Endocrinology, 1996
The serum concentration of testosterone was estimated from a population of wild lungfish over 6-7 years of sampling. Male lungfish were found to have high circulating levels of testosterone (approximately 50 ng/ml) which varied seasonally and could be correlated with spermatogenesis as judged by testis histology. Incubation of testis tissue slices with

Cephalic muscle development in the Australian lungfish,Neoceratodus forsteri

Journal of Morphology, 2017
AbstractLungfishes are the extant sister group of tetrapods. As such, they are important for the study of evolutionary processes involved in the water to land transition of vertebrates. The evolution of a true neck, that is, the complete separation of the pectoral girdle from the cranium, is one of the most intriguing morphological transitions known ...

Osteogenesis in the Australian lungfish, Neoceratodus forsteri (Osteichthyes: Dipnoi)

Australian Journal of Zoology, 2022
Several types of bone development are present in the Australian lungfish, Neoceratodus forsteri, the only extant member of the family Neoceratodontidae. In this species, dermal and parachondral bones form around the chondrocranium and mandible, to protect the brain and sense organs, to support the dentition and to facilitate oral function.
