Structure of an LGR dimer, an evolutionary predecessor of glycoprotein hormone receptors [PDF]

open access: yesNature Communications
Glycoprotein hormones (GpHs) produced in the human pituitary act through receptors (GpHRs) in the gonads to support reproduction and in the thyroid for metabolism.

Developmental effects of sulfated thyroid hormones in sea urchin skeletogenesis suggest activation of non-canonical thyroid hormone signaling pathway [PDF]

open access: yesFrontiers in Endocrinology
Thyroid hormones (THs) are essential regulators of metabolism, homeostasis, and development in metazoans. The canonical genomic pathway involves THs binding to nuclear thyroid hormone receptors (NTHRs), which modulate gene expression in vertebrates.

Role of StAR Gene in Sex Steroid Hormone Regulation and Gonadal Development in Ark Shell Scapharca broughtonii [PDF]

open access: yesBiology
This study elucidates the role of the steroidogenic acute regulatory protein (StAR) in sex steroid hormone dynamics and the gonadal development of the commercially important marine bivalve ark shell Scapharca broughtonii.

Invertebrate Gonadotropin-Releasing Hormone-Related Peptides and Their Receptors: An Update [PDF]

open access: yesFrontiers in Endocrinology, 2017
Gonadotropin-releasing hormones (GnRHs) play pivotal roles in reproductive functions via the hypothalamus, pituitary, and gonad axis, namely, HPG axis in vertebrates.

Ecdysteroids

open access: yesEncyclopedia, 2021
Ecdysteroid: member of a class of polyhydroxylated steroids found in invertebrate animals (zooecdysteroids; moulting hormones), plants (phytoecdysteroids) and fungi (mycoecdysteroids). Over 500 structural analogues are currently known.

Unconventional Actions of Glycoprotein Hormone Subunits: A Comprehensive Review

open access: yesFrontiers in Endocrinology, 2021
The glycoprotein hormones (GPH) are heterodimers composed of a common α subunit and a specific β subunit. They act by activating specific leucine-rich repeat G protein-coupled receptors. However, individual subunits have been shown to elicit responses in

Hormonal Regulation of Programmed Cell Death in Sea Urchin Metamorphosis

open access: yesFrontiers in Ecology and Evolution, 2021
Programmed cell death (PCD) has been identified as a key process in the metamorphic transition of indirectly developing organisms such as frogs and insects.

Steroid hormone regulation of innate immunity in Drosophila melanogaster.

open access: yesPLoS Genetics, 2023
Endocrine signaling networks control diverse biological processes and life history traits across metazoans. In both invertebrate and vertebrate taxa, steroid hormones regulate immune system function in response to intrinsic and environmental stimuli ...

A toxin-based approach to neuropeptide and peptide hormone discovery

open access: yesFrontiers in Molecular Neuroscience, 2023
Peptide hormones and neuropeptides form a diverse class of bioactive secreted molecules that control essential processes in animals. Despite breakthroughs in peptide discovery, many signaling peptides remain undiscovered.

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 ...
