A quantitative study of adipokinetic hormone of the firebug, Pyrrhocoris apterus [PDF]

open access: yes, 2002
The development of an enzyme-linked immunoassay (ELISA) for the adipokinetic neuropeptide hormone, Pya-AKH, from the firebug Pyrrhocoris apterus L. is described. The ELISA measures as little as 20 fmol of Pya-AKH.

Neurohormones in insect stress: A review [PDF]

open access: yesArchives of Biological Sciences, 2006
The neurohormones are the master regulators of all life processes in insects and they create a strategy of stress protecting events. Neurohormones are synthesized mainly in insect brain neurosecretory neurons.

Methoprene-tolerant (Met) knockdown in the adult female cockroach, Diploptera punctata completely inhibits ovarian development. [PDF]

open access: yesPLoS ONE, 2014
Independent of the design of the life cycle of any insect, their growth and reproduction are highly choreographed through the action of two versatile hormones: ecdysteroids and juvenile hormones (JH). However, the means by which JH can target tissues and

Eat to reproduce: a key role for the insulin signaling pathway in adult insects

open access: yesFrontiers in Physiology, 2013
Insects, like all heterotrophic organisms, acquire from their food the nutrients that are essential for anabolic processes that lead to growth (larval stages) or reproduction (adult stage).

Insect Body Defence Reactions against Bee Venom: Do Adipokinetic Hormones Play a Role?

open access: yesToxins, 2021
Bees originally developed their stinging apparatus and venom against members of their own species from other hives or against predatory insects. Nevertheless, the biological and biochemical response of arthropods to bee venom is not well studied.

Transcriptional Regulators of Ecdysteroid Biosynthetic Enzymes and Their Roles in Insect Development

open access: yesFrontiers in Physiology, 2022
Steroid hormones are responsible for coordinating many aspects of biological processes in most multicellular organisms, including insects. Ecdysteroid, the principal insect steroid hormone, is biosynthesized from dietary cholesterol or plant sterols.

Some effects of insect hormones on Na(^+), K(^+)-ATPase and fluid secretion by the malpighian tubules of locusta migratoria L [PDF]

open access: yes, 1981
A study has been made on the effects of insect hormones on fluid secretion by the Malpighian tubules of Locusta, and on the Na(^+), K(^+)- ATPase activity in microsomal preparations of the tubules.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Neuropeptide hormones from the eyestalks of Jasus Lalandii [PDF]

open access: yes, 2000
Bibliography: p. 242-264.The X-organ sinus gland complex, situated in the eyestalks of decapod crustaceans, are known to be a source of a variety of neuropeptide hormones that regulate a number of diverse physiological processes.
