Symbiosis with Dinoflagellates Alters Cnidarian Cell‐Cycle Gene Expression

open access: yesCellular Microbiology, Volume 2022, Issue 1, 2022., 2022
In the cnidarian‐dinoflagellate symbiosis, hosts show altered expression of genes involved in growth and proliferation when in the symbiotic state, but little is known about the molecular mechanisms that underlie the host’s altered growth rate.

Tailoring Flexible Arrays for Artificial Cilia Actuators

open access: yesAdvanced Intelligent Systems, Volume 3, Issue 10, October 2021., 2021
Inspired by structures, rhythms, and functions of natural cilia, artificial cilia actuators that can respond to stimuli such as light, electric, magnetism, etc. are developed to facilitate particle/fluid manipulation, sensing, robot design, and many other fields.

Concatenated analysis sheds light on early metazoan evolution and fuels a modern "urmetazoon" hypothesis. [PDF]

open access: yesPLoS Biology, 2009
For more than a century, the origin of metazoan animals has been debated. One aspect of this debate has been centered on what the hypothetical "urmetazoon" bauplan might have been.

Placozoan fiber cells: mediators of innate immunity and participants in wound healing

open access: yesScientific Reports, 2021
Placozoa is a phylum of non-bilaterian marine animals. These small, flat organisms adhere to the substrate via their densely ciliated ventral epithelium, which mediates mucociliary locomotion and nutrient uptake.

RNA interference in marine and freshwater sponges [PDF]

open access: yes, 2011
Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,

The evolution of the dystroglycan complex, a major mediator of muscle integrity [PDF]

open access: yes, 2015
Basement membrane (BM) extracellular matrices are crucial for the coordination of different tissue layers. A matrix adhesion receptor that is important for BM function and stability in many mammalian tissues is the dystroglycan (DG) complex.

Novel cell types, neurosecretory cells, and body plan of the early-diverging metazoan Trichoplax adhaerens. [PDF]

open access: yes, 2014
BACKGROUND: Trichoplax adhaerens is the best-known member of the phylum Placozoa, one of the earliest-diverging metazoan phyla. It is a small disk-shaped animal that glides on surfaces in warm oceans to feed on algae.

An evaluation of the evolution of the gene structure of dystroglycan [PDF]

open access: yes, 2017
BACKGROUND: Dystroglycan (DG) is an adhesion receptor complex composed of two non-covalently associated subunits, transcribed from a single gene. The extracellular α-DG is highly and heterogeneously glycosylated and binds with high affinity to laminins ...

The evolution of metazoan extracellular matrix [PDF]

open access: yes, 2011
The modular domain structure of extracellular matrix (ECM) proteins and their genes has allowed extensive exon/domain shuffling during evolution to generate hundreds of ECM proteins.

Multiple surveys employing a new sample‐processing protocol reveal the genetic diversity of placozoans in Japan [PDF]

open access: yes, 2018
Placozoans, flat free‐living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest‐branching metazoan phyla. They are widely distributed from temperate to tropical oceans.
