International Journal of Biological Macromolecules, 2016 At the end of each stadium, insects undergo a precisely orchestrated process known as ecdysis which results in the replacement of the old cuticle with a new one. This physiological event is necessary to accommodate growth in arthropods since they have a rigid chitinous exoskeleton.

Identification of Ecdysis-Triggering Hormone from an Epitracheal Endocrine System
Science, 1996 Developing insects repeatedly shed their cuticle by means of a stereotyped behavior called ecdysis, thought to be initiated by the brain peptide eclosion hormone. Here an ecdysis-triggering hormone, Mas-ETH, is described from the tobacco hornworm Manduca sexta .

Deletion of the ecdysis-triggering hormone gene leads to lethal ecdysis deficiency
Development, 2002 At the end of each developmental stage, insects perform a stereotypic behavioral sequence leading to ecdysis of the old cuticle. While ecdysis-triggering hormone (ETH) is sufficient to trigger this sequence, it has remained unclear whether it is required.

Identification of Ecdysis-Triggering Hormone in the SilkwormBombyx mori
Biochemical and Biophysical Research Communications, 1997 Ecdysis, the shedding of cuticle at the end of each life stage, is critical to the postembryonic development of insects. The endocrine regulation of ecdysis has been highlighted by the recent description of the epitracheal endocrine system in the tobacco hornworm Manduca sexta, which produces ecdysis-triggering hormone (Mas-ETH).

Insect Molecular Biology, 2022 Abstract Ecdysis triggering hormone (ETH) was originally discovered as a key hormone that regulates insect moulting via binding to its receptor, ETH receptor (ETHR). However, the precise role of ETH in moth reproduction remains to be explored in detail.

Regulation of Ecdysis-Triggering Hormone Release by Eclosion Hormone
Journal of Experimental Biology, 1997 ABSTRACT Ecdysis behavior in the tobacco hornworm Manduca sexta (Lepidoptera: Sphingidae) is triggered through reciprocal peptide signaling between the central nervous system and the epitracheal endocrine system. Recent evidence indicates that eclosion hormone may initiate endocrine events leading to ecdysis through its action on ...

Molecular identification of the first insect ecdysis triggering hormone receptors
Biochemical and Biophysical Research Communications, 2002 The Drosophila Genome Project website (www.flybase.org) contains an annotated gene sequence (CG5911), coding for a G protein-coupled receptor. We cloned the cDNA corresponding to this sequence and found that the gene has not been correctly predicted. The corrected gene CG5911 has five introns and six exons (1-6).

Molecular cloning and function of ecdysis-triggering hormones in the silkwormBombyx mori
Journal of Experimental Biology, 2002 SUMMARYInka cells of the epitracheal endocrine system produce peptide hormones involved in the regulation of insect ecdysis. In the silkworm Bombyx mori, injection of Inka cell extract into pharate larvae, pupae or adults activates the ecdysis behavioural sequence.

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2019 Neuropeptide ecdysis triggering hormone (ETH) plays crucial roles in invertebrates by activating a G protein-coupled receptor (GPCR), the ecdysis triggering hormone receptor (ETHR), which has been intensively investigated in Hexapoda. However, the molecular characterization of ETH and ETHR in Chelicerata remains unknown.

Insect Molecular Biology, 2020 Abstract In Drosophila melanogaster , ecdysis triggering hormone (ETH) is the key factor triggering ecdysis behaviour and promoting trachea clearance. However, whether ETH plays the dual roles in non‐dipteran insects is unknown. In this survey, we found that
