Function and phylogeny support the independent evolution of an ASIC-like Deg/ENaC channel in the Placozoa

open access: yesCommunications Biology, 2023
ASIC channels are bilaterian proton-gated sodium channels belonging to the large and functionally-diverse Deg/ENaC family that also includes peptide- and mechanically-gated channels.

Differentiation of Crystal Cells, Gravity-Sensing Cells in the Placozoan Trichoplax adhaerens

open access: yesJournal of Marine Science and Engineering, 2021
Trichoplax adhaerens are simple animals with no nervous system, muscles or body axis. Nevertheless, Trichoplax demonstrate complex behaviors, including responses to the direction of the gravity vector.

The origin of the Hox/ParaHox genes, the Ghost Locus hypothesis and the complexity of the first animal [PDF]

open access: yes, 2015
A key aim in evolutionary biology is to deduce ancestral states in order to better understand the evolutionary origins of clades of interest and the diversification process(es) that have elaborated them.

The Buds of Oscarella lobularis (Porifera, Homoscleromorpha): A New Convenient Model for Sponge Cell and Evolutionary Developmental Biology

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 8, Page 503-528, December 2024.
We describe a technique for triggering asexual reproduction by budding in vitro and have monitored bud development. The natural properties of Oscarella lobularis buds and the technical tools we developed make them a new biological system for getting insights into sponge molecular and cellular processes.

Bodily Complexity:Integrated Multicellular Organizations for Contraction-Based Motility [PDF]

open access: yes, 2019
Compared to other forms of multicellularity, the animal case is unique. Animals—barring some exceptions—consist of collections of cells that are connected and integrated to such an extent that these collectives act as unitary, large free-moving entities ...

Alternative NAD(P)H dehydrogenase and alternative oxidase: proposed physiological roles in animals [PDF]

open access: yes, 2019
The electron transport systems in mitochondria of many organisms contain alternative respiratory enzymes distinct from those of the canonical respiratory system depicted in textbooks.

Origin and evolution of microvilli

open access: yesBiology of the Cell, Volume 116, Issue 11, November 2024.
Microvilli are widespread organelles of animal cells that frequently play a role in sensation and feeding. Ansel et al. reconstitute their origin and evolution by performing a broad morphological survey of microvilli in animals and their unicellular relatives, coupled with a bioinformatic study of the phylogenetic distribution of the main microvillar ...

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

open access: yes, 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 ...

Comparative multiomics analyses reveal the breed effect on the colonic host–microbe interactions in pig

open access: yesiMetaOmics, 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 ...
