Phylogenetic analysis of the endoribonuclease Dicer family. [PDF]

open access: yesPLoS ONE, 2014
Dicers are proteins of the ribonuclease III family with the ability to process dsRNA, involved in regulation of gene expression at the post-transcriptional level.

The evolution and comparative neurobiology of endocannabinoid signalling [PDF]

open access: yes, 2012
CB(1)- and CB(2)-type cannabinoid receptors mediate effects of the endocannabinoids 2-arachidonoylglycerol (2-AG) and anandamide in mammals. In canonical endocannabinoid-mediated synaptic plasticity, 2-AG is generated postsynaptically by diacylglycerol ...

Molecular mechanisms of perilipin protein function in lipid droplet metabolism

open access: yesFEBS Letters, Volume 598, Issue 10, Page 1170-1198, May 2024.
Lipid droplets (LDs) are important for the storage of energy and lipid components. The perilipin family in mammals includes five proteins (PLIN1 to PLIN5), all of which are abundant on the surface of LDs in different tissues and play a role in LD stability and degradation by lipases.

Evolution of the perlecan/HSPG2 gene and its activation in regenerating Nematostella vectensis. [PDF]

open access: yesPLoS ONE, 2015
The heparan sulfate proteoglycan 2 (HSPG2)/perlecan gene is ancient and conserved in all triploblastic species. Its presence maintains critical cell boundaries in tissue and its large (up to ~900 kDa) modular structure has prompted speculation about the ...

Beauty in the beast – Placozoan biodiversity explored through molluscan predator genomics

open access: yesEcology and Evolution, Volume 14, Issue 4, April 2024.
Previous assumptions about the primary habitat of Placozoa are challenged, and their broader diversity beyond disc‐shaped grazers in coastal waters is revealed. The discovery of placozoan‐predatory sea slugs prompts consideration of a new ecological niche: seafloor sediment interstices.

Phylogenetic position of Placozoa based on large subunit (LSU) and small subunit (SSU) rRNA genes

open access: yesGenetics and Molecular Biology, 2007
The phylum Placozoa, represented by its single species Trichoplax adhaerens, has always been considered one of the most basal animal clades due to its low morphological complexity.

Functional characterization of p53 pathway components in the ancient metazoan Trichoplax adhaerens [PDF]

open access: yesScientific Reports, 2016
AbstractThe identification of genes encoding a p53 family member and an Mdm2 ortholog in the ancient placozoan Trichoplax adhaerens advocates for the evolutionary conservation of a pivotal stress-response pathway observed in all higher eukaryotes. Here, we recapitulate several key functionalities ascribed to this known interacting protein pair by ...

Proteoglycans in mechanobiology of tissues and organs: Normal functions and mechanopathology

open access: yesProteoglycan Research, Volume 2, Issue 2, April-June 2024.
Abstract Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key

Coordinated cellular behavior regulated by epinephrine neurotransmitters in the nerveless placozoa

open access: yesNature Communications
Understanding how cells communicated before the evolution of nervous systems in early metazoans is key to unraveling the origins of multicellular life.

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.
