Lancelets (‘amphioxus’) are the modern survivors of an ancient chordate lineage, with a
fossil record dating back to the Cambrian period. Here we describe the structure and gene …

Small GTP-binding proteins regulate diverse processes in eukaryotic cells such as signal
transduction, cell proliferation, cytoskeletal organization, and intracellular membrane trafficking…

The hypothesis that the S allele of the 5-HTTLPR serotonin transporter promoter region is
associated with increased risk of depression, but only in individuals exposed to stressful …

Background There are high levels of comorbidity between schizophrenia and substance
use disorder, but little is known about the genetic etiology of this comorbidity. Methods We …

… Horton a , Dana B. Hancock b , Timothy B. Baker … Hartz, Horton and Bierut designed and
conducted statistical analyses. All authors contributed to data harmonization and interpretation …

T-box genes encode a family of DNA-binding transcription factors implicated in numerous
developmental processes in all metazoans. The Tbx2/3/4/5 subfamily genes are especially …

We have isolated an amphioxus T-box gene that is orthologous to the two vertebrate genes,
Tbx1 and Tbx10, and examined its expression pattern during embryonic and early larval …

We have identified an amphioxus T‐box gene that is orthologous to the Eomesodermin, T‐brain‐1,
and Tbx21 genes of vertebrates, and we have characterized its expression pattern …

We have sampled a large number of plant taxa, ranging from brown algae to angiosperms,
for the presence of myosin sequences. Using phylogenetic analysis, we show that all but two …

The widely accepted notion that two whole‐genome duplications occurred during early
vertebrate evolution (the 2R hypothesis) stems from the fact that vertebrates often possess …
