Histone Deacetylase 3 Is Involved in Maintaining Queen Hallmarks of a Termite
Molecular Ecology, Volume 33, Issue 22, November 2024.ABSTRACT The role of epigenetics in regulating caste polyphenism in social insects has been debated. Here, we tested the importance of histone de/acetylation processes for the maintenance of queen hallmarks like a high fecundity and a long lifespan.

European Journal of Entomology, 2015 This article is a comprehensive summary of the 50-year history of physiological investigations in the Czech Republic into the mode of action of the corpus allatum hormone (CAH) in insects, which is commonly known as the juvenile hormone (JH). During this

Egfr signaling promotes juvenile hormone biosynthesis in the German cockroach
BMC Biology, 2022 Background In insects, an interplay between the activities of distinct hormones, such as juvenile hormone (JH) and 20-hydroxyecdysone (20E), regulates the progression through numerous life history hallmarks.

A quantitative assay for the juvenile hormones and their precursors using fluorescent tags. [PDF]
PLoS ONE, 2012 The juvenile hormones (JHs) are sesquiterpenoid compounds that play a central role in insect reproduction, development and behavior. The lipophilic nature of JHs and their precursors, in conjunction with their low concentration in tissues and ...

Mevalonate-Farnesal Biosynthesis in Ticks: Comparative Synganglion Transcriptomics and a New Perspective. [PDF]
PLoS ONE, 2016 Juvenile hormone (JH) controls the growth, development, metamorphosis, and reproduction of insects. For many years, the general assumption has been that JH regulates tick and other acarine development and reproduction the same as in insects.

HISTOLOGY OF THE CORPORA ALLATA OF MELANOPLUS DIFFERENTIALIS (ORTHOPTERA: SALTATORIA)
The Biological Bulletin, 1948 1. The corpora allata of the grasshopper Melanoplus differentialis were studied histologically to determine whether these glands show changes related to their functions in the control of nymphal development and the production of ripe eggs and oviducal secretion.2. Four classes of cells were recognized in the corpora allata of this insect: a, connective

Nitric oxide/cGMP signaling in the corpora allata of female grasshoppers
Journal of Insect Physiology, 2011 The corpora allata (CA) of various insects express enzymes with fixation resistant NADPHdiaphorase activity. In female grasshoppers, juvenile hormone (JH) released from the CA is necessary to establish reproductive readiness, including sound production.

PLoS ONE, 2017 Juvenile hormone (JH) regulates development and reproductive maturation in insects. The corpora allata (CA) from female adult mosquitoes synthesize fluctuating levels of JH, which have been linked to the ovarian development and are influenced by ...
