Confocal Characterization of Intestinal Dendritic Cells from Myxines to Teleosts

open access: yesBiology, 2022
Dendritic cells (DCs) are antigen-presenting cells (APCs) that regulate the beginning of adaptive immune responses. The mechanisms of tolerance to antigens moving through the digestive tract are known to be regulated by intestinal DCs.

First Devonian dipnoans (Vertebrata, Sarcopterygii) from Spitsbergen

open access: yesComptes Rendus Palevol, 2006
For the first time, dipnoan remains are described from the Devonian of Spitsbergen. According to the stratigraphy and the associated vertebrate fauna, they are considered as Late Emsian–Early Eifelian in age. Unfortunately remains are too sketchy and non-diagnostic to be referred or compared to a known Devonian dipnoan. This new material, determined as

The Tatuí Formation (Early Permian, Paraná Basin), Brazil: Paleontology and Paleoenvironmental Considerations

open access: yesEarth Sciences Research Journal, 2015
The Tatuí Formation, one of the Brazilian Paraná Basin geological units, is developed solely in the State of São Paulo, southeast Brazil. It is studied herein, through outcrops at the eastern border of the basin, which are siltstones and fine sandstones,

Suction feeding of West African lungfish (Protopterus annectens): An XROMM analysis of jaw mechanics, cranial kinesis, and hyoid mobility

open access: yesBiology Open, 2022
Suction feeding in fishes is characterized by rapid cranial movements, but extant lungfishes (Sarcopterygii: Dipnoi) exhibit a reduced number and mobility of cranial bones relative to actinopterygian fishes. Despite fusion of cranial elements, lungfishes

Evolutionary history of glucose-6-phosphatase encoding genes in vertebrate lineages: towards a better understanding of the functions of multiple duplicates

open access: yesBMC Genomics, 2017
Background Glucose-6-phosphate (G6pc) is a key enzyme involved in the regulation of the glucose homeostasis. The present study aims at revisiting and clarifying the evolutionary history of g6pc genes in vertebrates.

The first draft genome assembly and data analysis of the Malaysian mahseer (Tor tambroides)

open access: yesAquaculture and Fisheries, 2023
The Malaysian mahseer (Tor tambroides), one of the most valuable freshwater fish in the world, is mainly targeted for human consumption. The mitogenomic data of this species is available to date, but the genomic information is still lacking.

Evolution and differential expression of a vertebrate vitellogenin gene cluster

open access: yesBMC Evolutionary Biology, 2009
Background The multiplicity or loss of the vitellogenin (vtg) gene family in vertebrates has been argued to have broad implications for the mode of reproduction (placental or non-placental), cleavage pattern (meroblastic or holoblastic) and character of ...

Phylogenomics Based on Transcriptome Data Provides Evidence for the Internal Phylogenetic Relationships and Potential Terrestrial Evolutionary Genes of Lungfish

open access: yesFrontiers in Marine Science, 2021
The evolutionary relationships of lungfish can provide crucial information on the transition from Sarcopterygii to tetrapods. Phylogenomics is necessary to explore accurate internal phylogenetic relationships among all lungfish species. In the context of
