Transfer of Potentially Toxic Metal(loid)s From Ultramafic Soils in a Tri‐Trophic Food Chain Experiment

Ecological Research, Volume 41, Issue 5, September 2026.
Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant‐herbivore‐predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM‐enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by ...

Comparison of the X-ray absorption properties of the binuclear active site of molluscan and arthropodan hemocyanins

, 2002
The structural characteristics of oxy- and deoxy-hemocyanins have been investigated using X-ray absorption spectroscopy both in the near-edge (XANES) and for the first shell contribution in the EXAFS region.

Developmental Fates of Progenitor/Undifferentiated Cells With Histone Trimethylation Tags in the Stony Coral, Acropora tenuis

Development, Growth &Differentiation, Volume 68, Issue 7, September 2026.
In the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...

The antimicrobial peptides of the immune response of shrimp [PDF]

Invertebrate Survival Journal, 2008
The cultivation of penaeid shrimp is a worldwide economic activity which has the potential to contribute to increasing shrimp production. However, penaeid shrimps are susceptible to bacterial and viral diseases, and may thus cause significant losses to ...

A respiratory hemocyanin from an insect [PDF]

Proceedings of the National Academy of Sciences, 2004
Insects possess an elaborate tracheal system that enables transport of gaseous oxygen from the atmosphere directly to the inner organs. Therefore, the presence of specialized oxygen-transport proteins in the circulatory system of insects has been considered generally unnecessary.

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, Volume 16, Issue 8, Page 1491-1500, August 2026.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

Advanced Science, Volume 13, Issue 43, 3 August 2026.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

Hemocyanins as immunostimulants Hemocianinas, una herramienta inmunológica de la biomedicina actual [PDF]

, 2011
Hemocyanins, the giant oxygen transporter glycoproteins of diverse mollusks, are xenogenic to the mammalian immune system and they display a remarkable immunogenicity.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

Advanced Science, Volume 13, Issue 46, 17 August 2026.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...
