Comparative Neurobiology of Biogenic Amines in Animal Models in Deuterostomes
Frontiers in Ecology and Evolution, 2020 We review the occurrence of biogenic amines and their potential role as neurotransmitters in the nervous system of three groups of invertebrate deuterostomes: tunicates, cephalochordates, and echinoderms.

Asymmetron lucayanum: How many species are valid?
PLoS ONE, 2020 The cephalochordates amphioxus or lancelets are benthic marine animals representing the earliest divergent evolutionary lineage within chordates. Although amphioxus are present in most of the world's tropical and temperate oceans, only about thirty ...

Evolution of a core gene network for skeletogenesis in chordates. [PDF]
PLoS Genetics, 2008 The skeleton is one of the most important features for the reconstruction of vertebrate phylogeny but few data are available to understand its molecular origin. In mammals the Runt genes are central regulators of skeletogenesis.

LanceletDB: an integrated genome database for lancelet, comparing domain types and combination in orthologues among lancelet and other species [PDF]
Database, 2019 Lancelet (amphioxus) represents the most basally divergent extant chordate (cephalochordates) that diverged from the other two chordate lineages (urochordates and vertebrates) more than half a billion years ago. As it occupies a key position in evolution, it is considered as one of the best proxies for understanding the chordate ancestral state.

Chromosomes of the Lancelet Branchiostoma belcheri Gray [PDF]
Zoological Science, 2001 Abstract We characterized the chromosomes of the lancelet Branchiostoma belcheri Gray. Testes were removed from adult males, cut up, treated with colchicine (25–50 μg/ml) for 3–6 hr, and dissociated into single cells by pippeting. The dissociated cells were swollen with 5.0–6.5% sodium citrate for 10 min and fixed with methanol-acetic acid (3:1).

Frontiers in Ecology and Evolution, 2016 Molecular fingerprinting of conserved germline and somatic ¨stemness¨ markers in different taxa have been key in defining the mechanism of germline specification (preformation or epigenesis), as well as expression domains of somatic progenitors.

On Branchiostoma californiense (Cephalochordata) from the Gulf of Nicoya estuary, Costa Rica
Revista de Biología Tropical, 2010 The cephalochordates are represented by the lancelets, of which species of the genus Branchiostoma are the best known. In recent years, these organisms have been the center of activity of studies focusing on the phylogenetic relationships of the ...

Evolutionary history of the extant amphioxus lineage with shallow-branching diversification
Scientific Reports, 2017 Amphioxus or lancelets have been regarded as a key animal in understanding the origin of vertebrates. However, the evolutionary history within this lineage remains unexplored.

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.
