Relationship between Rab and insulin-like proteins in the nervous system of Bombyx mori

open access: yesEuropean Journal of Entomology, 2021
Rab proteins are small GTP-binding proteins and are the largest family in the Ras GTPase superfamily and mediate vesicular transport in cells. Diverse insulin-like peptides, such as bombyxin, are synthesized in the brain and secreted into the haemolymph ...

Two Undervalued Functions of the Golgi Apparatus: Removal of Excess Ca2+ and Biosynthesis of Farnesol-Like Sesquiterpenoids, Possibly as Ca2+-Pump Agonists and Membrane “Fluidizers–Plasticizers”

open access: yesFrontiers in Physiology, 2020
The extensive literature dealing with the Golgi system emphasizes its role in protein secretion and modification, usually without specifying from which evolutionary ancient cell physiological necessity such secretion originated.

Regulation of Drosophila Long-Term Courtship Memory by Ecdysis Triggering Hormone

open access: yesFrontiers in Neuroscience, 2021
Endocrine state is an important determinant of learning and memory in animals. In Drosophila, rejection of male courtship overtures by mated females leads to an aversive response manifested as courtship memory.

Relationships between locomotor activity, oxidative damage and life span in males and females of the linden bug, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2013
In this study we addressed a question of whether experimental manipulations that increase life span also reduce physical activity and molecular oxidative damage.

Peptide Hormones in the Insect Midgut

open access: yesFrontiers in Physiology, 2020
Insects produce many peptide hormones that play important roles in regulating growth, development, immunity, homeostasis, stress, and other processes to maintain normal life. As part of the digestive system, the insect midgut is also affected by hormones

Model of the insulin pathway regulating the expression of the HMGCR in the corpus allatum. [PDF]

open access: yes, 2013
We hypothesize that the two different populations of cells, the Insulin Producing Cells (IPCs) and the feminising cells (FCs), located in the pars intercerebralis control, by two distinct ways, the JH synthesis/release by the corpus allatum.

Regulation of the development of flight muscles in long-winged adults of the flightless bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

open access: yesEuropean Journal of Entomology, 2008
We studied the development of the indirect flight muscles and reproductive organs in long-winged (macropterous) adults of the flightless bug Pyrrhocoris apterus (L.) and the factors involved in flight muscles histolysis by means of total protein analysis.

Glutamate-induced rise in cytosolic calcium concentration stimulates in vitro rates of juvenile hormone biosynthesis in corpus allatum of Diploptera punctata [PDF]

open access: yes, 2010
[[abstract]]We show that in a cockroach, Diploptera punctata, endocrine function of the corpus allatum may be modulated by L-glutamate, a major fast excitatory neurotransmitter in the central nervous system of vertebrates and invertebrates.

Effects of proallatotoxins (precocenes) on the development and reproduction of Rhodnius prolixus: some data

open access: yesMemorias do Instituto Oswaldo Cruz, 1991
Proallatotoxins, and particularly preconcenes, are exceptionally promising models for studying Rhodnius prolixus physiology and for comparison with other natural compounds with anti-hormonal activities.

Endocrine modulation of primary chemosensory neurons regulates Drosophila courtship behavior.

open access: yesPLoS Genetics, 2022
The decision to engage in courtship depends on external cues from potential mates and internal cues related to maturation, health, and experience. Hormones allow for coordinated conveyance of such information to peripheral tissues.
