The Role of Monoaminergic Neurotransmission for Metabolic Control in the Fruit Fly Drosophila Melanogaster

Frontiers in Systems Neuroscience, 2017
Hormones control various metabolic traits comprising fat deposition or starvation resistance. Here we show that two invertebrate neurohormones, octopamine (OA) and tyramine (TA) as well as their associated receptors, had a major impact on these metabolic

Conservation of progesterone hormone function in invertebrate reproduction [PDF]

Proceedings 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.

Hormones in Invertebrates [PDF]

Nature, 1940
OF recent years increasing attention has been paid to invertebrates to determine whether they provide evidence of chemical correlation similar to those hormonal reactions that are now recognized as being of tremendous physiological and philosophical importance in the life of man and other vertebrates. Even in 1933 the view was held by some workers that

Cell signalling in the immune response of mussel hemocytes [PDF]

Invertebrate Survival Journal, 2006
In this work data on immune cell signallling in the circulating hemocytes of the edible bivalve, themussel Mytilus spp, are summarized. Studies with different bacterial species and strains, heterologouscytokines and natural hormones, as well as with ...

Characterization of the neurohypophysial hormone gene loci in elephant shark and the Japanese lamprey: origin of the vertebrate neurohypophysial hormone genes

BMC Evolutionary Biology, 2009
Background Vasopressin and oxytocin are mammalian neurohypophysial hormones with distinct functions. Vasopressin is involved mainly in osmoregulation and oxytocin is involved primarily in parturition and lactation.

Signalling through pigment dispersing hormone-like peptides in invertebrates [PDF]

Progress in Neurobiology, 2011
During recent decades, several research teams engaged in unraveling the molecular structure and the physiological significance of pigment dispersing hormone-like peptides, particularly with respect to colour change and biological rhythms. In this review, we first summarise the entire history of pigment dispersing hormone-like peptide research, thus ...

Steroid Hormones in the Aquatic Environment – Review of the State of Knowledge and Comparison of Surface Water Pollution between Europe and Asia

Studia Ecologiae et Bioethicae
Steroid hormones are fundamental regulators of physiological processes in both animals and humans. The aim of this mini review is to present key findings in recent years regarding the presence and impact of steroid hormones on the natural environment ...

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Feeding and the rhodopsin family G-Protein Coupled Receptors (GPCRs) in nematodes and arthropods

Frontiers in Endocrinology, 2012
In vertebrates, receptors of the rhodopsin G-protein coupled superfamily (GPCRs) play an important role in the regulation of feeding and energy homeostasis and are activated by peptide hormones produced in the brain-gut axis.

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

Advanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support
