Never ending analysis of a century old evolutionary debate: unringing the urmetazoon bell
Frontiers in Ecology and Evolution, 2016 Our understanding of the early evolution of animals will be greatly improved if a final solution can be found to the evolutionary relationships between Porifera, Placozoa, Ctenophora, Cnidaria and Bilateria.

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.

EvoDevo, 2010 Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Trichoplax, the simplest known animal, contains an estrogen-related receptor: Implications for the evolution of vertebrate and invertebrate estrogen receptors [PDF]
, 2008 Although, as their names imply, vertebrate and invertebrate estrogen receptors [ERs] and estrogen-related receptors [ERRs] are related transcription factors, their evolutionary relationships to each other are not fully understood.

Profiling G protein-coupled receptors of Fasciola hepatica identifies orphan rhodopsins unique to phylum Platyhelminthes [PDF]
, 2017 G protein-coupled receptors (GPCRs) are established drug targets. Despite their considerable appeal as targets for next-generation anthelmintics, poor understanding of their diversity and function in parasitic helminths has thwarted progress towards GPCR-

iMetaOmics, Volume 1, Issue 1, September 2024.The colon contents of the Jiaxing Black (JXB) and the Duroc × Landrace × Yorkshire (DLY) pigs were collected for transcriptomic and metagenomic analyses. By using Weighted Gene Co‐expression Network Analysis and sparse Canonical correlation analysis, we identified the potential interactions between host genes and gut microbes, indicating that host ...

Getting Nervous: An Evolutionary Overhaul for Communication. [PDF]
, 2017 The evolution of a nervous system as a control system of the body's functions is a key innovation of animals. Its fundamental units are neurons, highly specialized cells dedicated to fast cell-cell communication.

PLoS ONE, 2018 Trichoplax adhaerens has only six cell types. The function as well as the structure of crystal cells, the least numerous cell type, presented an enigma. Crystal cells are arrayed around the perimeter of the animal and each contains a birefringent crystal.
