Amphioxus makes the cut—Again [PDF]
Communicative & Integrative Biology, 2012 The cephalochordate amphioxus is now established as an important model system for understanding the evolution of vertebrate novelties from an invertebrate chordate ancestor. It is also emerging as a serious candidate for studies of organ regeneration.

The amphioxus immune system [PDF]
Invertebrate Survival Journal, 2007 The cephalochordate amphioxus is the closest living invertebrate relative of the vertebrates and therefore it can provide useful insights on the evolution of the adaptive immune system.

A neurochemical map of the developing amphioxus nervous system [PDF]
BMC Neuroscience, 2012 Background Amphioxus, representing the most basal group of living chordates, is the best available proxy for the last invertebrate ancestor of the chordates.

Optical Clearing and Light Sheet Microscopy Imaging of Amphioxus [PDF]
Frontiers in Cell and Developmental Biology, 2021 Cephalochordates (amphioxi or lancelets) are representatives of the most basally divergent group of the chordate phylum. Studies of amphioxus development and anatomy hence provide a key insight into vertebrate evolution.

The Ontology of the Amphioxus Anatomy and Life Cycle (AMPHX)
Frontiers in Cell and Developmental Biology, 2021 An ontology is a computable representation of the different parts of an organism and its different developmental stages as well as the relationships between them.

Asymmetric distribution of pl10 and bruno2, new members of a conserved core of early germline determinants in cephalochordates [PDF]
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.

Broken colinearity of the amphioxus
EvoDevo, 2012 Background In most eumetazoans studied so far, Hox genes determine the identity of structures along the main body axis. They are usually linked in genomic clusters and, in the case of the vertebrate embryo, are expressed with spatial and temporal ...

Amphioxus: a peaceful anchovy fillet to illuminate Chordate Evolution (II)
International Journal of Biological Sciences, 2006 The genome of the amphioxus is on the horizon. With Linda Holland and Jeremy Gibson-Brown at the forefront, with all the amphioxus community behind, and with the Joint Genome Institute, the amphioxus genome will see the light this year, 2006.

Substrate for Thyroid Hormone Synthesis: Biochemistry, Evolution, and Physiology. [PDF]
FASEB JTwo proposed sequence of events for thyroxine formation in patients expressing mutant thyroglobulin. (A) (1) TSH stimulation drives expression of misfolded TG. (2) Unremitting ER stress. (3) Stress‐induced cell death. (4) Dead thyrocytes release their contents. (5) The contents become iodinated. (6) Forming thyroxine.
