Domain‐Shuffling in the Evolution of Cyclostomes and Gnathostomes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 59-79, March 2025.
We addressed the potential roles of domain‐shuffling origin genes (DSO‐Gs) in the evolution of early vertebrates. Through comparative genome analysis of 22 metazoans, including four cyclostomes, we identified DSO‐Gs before and after the divergence of cyclostomes and gnathostomes, and suggest domain shuffling as a key mechanism in vertebrate early ...

The placozoan Trichoplax

Nature Methods
After having been largely neglected for more than a century, the tiny marine animal Trichoplax adhaerens is enjoying a revival and is now poised to become a mainstream model organism for the study of epithelial evolution, diversification and specialization.

Distinct expression patterns of the two T-box homologues Brachyury and Tbx2/3 in the placozoan Trichoplax adhaerens [PDF]

, 2018
Trichoplax adhaerens is the only species known from the phylum Placozoa with one of the simplest metazoan body plans. In the small disc-like organism an upper and a lower epithelium can be distinguished with a less compact third cell layer in between ...

Developmental gene expression in the eyes of the pygmy squid Xipholeptos notoides

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 7, Page 483-498, November 2024.
In the cephalopod Xipholeptos notoides, the photosensitive pigment encoding genes Rhodopsin, Xenopsin, and Retinochrome, as well as two Reflectin genes are expressed in the olfactory organ. This suggests that either opsins may not only be involved in photoreception or the olfactory organ is involved in photoreception.

Evolution of the Cdk4/6–Cdkn2 system in invertebrates

Genes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

The origin and evolution of G protein-coupled receptor kinases. [PDF]

PLoS ONE, 2012
G protein-coupled receptor (GPCR) kinases (GRKs) play key role in homologous desensitization of GPCRs. GRKs phosphorylate activated receptors, promoting high affinity binding of arrestins, which precludes G protein coupling.

Homoplasy in genome-wide analysis of rare amino acid replacements: the molecular-evolutionary basis for Vavilov's law of homologous series [PDF]

, 2008
Background Rare genomic changes (RGCs) that are thought to comprise derived shared characters of individual clades are becoming an increasingly important class of markers in genome-wide phylogenetic studies.

Protein tyrosine phosphatase 1B (PTP1B) function, structure, and inhibition strategies to develop antidiabetic drugs

FEBS Letters, Volume 598, Issue 15, Page 1811-1838, August 2024.
This Review presents the main advances in the study of PTP1B since it was first isolated, and recent contextual information related to this protein. Furthermore, we provide an overview of the role of PTP1B in diabetes and obesity, and the challenges of developing selective, effective, potent, bioavailable, and cell‐permeable compounds that can inhibit ...

Studying Placozoa WBR in the Simplest Metazoan Animal, Trichoplax adhaerens

, 2022
AbstractPlacozoans are a promising model system to study fundamental regeneration processes in a morphologically and genetically very simple animal. We here provide a brief introduction to the enigmatic Placozoa and summarize the state of the art of animal handling and experimental manipulation possibilities.
