Fat Body—Multifunctional Insect Tissue

open access: yesInsects, 2021
The biodiversity of useful organisms, e.g., insects, decreases due to many environmental factors and increasing anthropopressure. Multifunctional tissues, such as the fat body, are key elements in the proper functioning of invertebrate organisms and ...

Knockdown of Two Iodothyronine Deiodinase Genes Inhibits Epinephrine-Induced Larval Metamorphosis of the Hard-Shelled Mussel Mytilus coruscus

open access: yesFrontiers in Marine Science, 2022
The metamorphosis process is a critical life-changing event for marine invertebrate planktonic larvae to transform into benthic adults, which is crucial for the shellfish bed’s ecosystem stability and seed production in aquaculture.

Structure-Function Relationships of Glycoprotein Hormones and their Subunits' Ancestors

open access: yesFrontiers in Endocrinology, 2015
Glycoprotein hormones (GPHs) are the most complex molecules with hormonal activity. They exist only in vertebrates but the genes encoding their subunits ancestors are found in most vertebrate invertebrate species although their roles are still unknown.In

Thyroid hormone membrane receptor binding and transcriptional regulation in the sea urchin Strongylocentrotus purpuratus

open access: yesFrontiers in Endocrinology, 2023
Thyroid hormones (THs) are small amino acid derived signaling molecules with broad physiological and developmental functions in animals. Specifically, their function in metamorphic development, ion regulation, angiogenesis and many others have been ...

Leucokinins: Multifunctional Neuropeptides and Hormones in Insects and Other Invertebrates [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Leucokinins (LKs) constitute a neuropeptide family first discovered in a cockroach and later identified in numerous insects and several other invertebrates. The LK receptors are only distantly related to other known receptors. Among insects, there are many examples of species where genes encoding LKs and their receptors are absent.

A Study on the Anti-NF-κB, Anti-Candida, and Antioxidant Activities of Two Natural Plant Hormones: Gibberellin A4 and A7

open access: yesPharmaceutics, 2022
Introduction: Gibberellins (GA) are terpenoids that serve as important plant hormones by acting as growth and response modulators against injuries and parasitism.

The microbiome of the invertebrate model host Galleria mellonella is dominated by Enterococcus

open access: yesAnimal Microbiome, 2019
Background The popularity of Galleria mellonella as invertebrate model is increasing rapidly, because it forms an attractive alternative to study bacterial, fungal and viral infections, toxin biology, and to screen antimicrobial drugs.

Conservation of progesterone hormone function in invertebrate reproduction [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Steroids play fundamental roles regulating mammalian reproduction and development. Although sex steroids and their receptors are well characterized in vertebrates and several arthropod invertebrates, little is known about the hormones and receptors regulating reproduction in other invertebrate species.

Ultraspiracle: An invertebrate nuclear receptor for juvenile hormones [PDF]

open access: yesProceedings of the National Academy of Sciences, 1997
Juvenile hormones (JH), a sesquiterpenoid group of ligands that regulate developmental transitions in insects, bind to the nuclear receptor ultraspiracle (USP). In fluorescence-based binding assays, USP protein binds JH III and JH III acid with specificity, adopting for each ligand a different final conformational state.
