Ecdysone coordinates plastic growth with robust pattern in the developing wing

open access: yeseLife, 2022
Animals develop in unpredictable, variable environments. In response to environmental change, some aspects of development adjust to generate plastic phenotypes.

Ecdysone Quantification from Whole Body Samples of Drosophila melanogaster Larvae

open access: yesBio-Protocol, 2021
Steroid hormones strictly control the timing of sexual maturation and final body size both in vertebrates and invertebrates. In insects, the steroid hormone ecdysone controls the timing of the molts between larval instars as well as the transition to ...

Mechanisms of transcriptional regulation of ecdysone response

open access: yesВавиловский журнал генетики и селекции, 2019
The mechanisms of ecdysone-dependent expression have been studied for many decades. Initially, the activation of individual genes under the influence of ecdysone was studied on the model of polythene chromosomes from salivary glands of Drosophila ...

Ecdysone Elicits Chronic Renal Impairment via Mineralocorticoid-Like Pathogenic Activities [PDF]

open access: yesCellular Physiology and Biochemistry, 2018
Background/Aims: Ecdysteroids are steroidal insect molting hormones that also exist in herbs. Ecdysteroid-containing adaptogens have been popularly used to improve well-being and by bodybuilders for muscle growth.

The insulin and ecdysone pathways as regulators of diapause termination: transcriptional and protein insights from Pieris napi [PDF]

open access: yesBMC Genomics
Insect diapause is a pre-programmed alternative developmental pathway induced to survive adverse environmental conditions and is characterized by an absence of development, metabolic suppression and increased stress resistance.

A Genetic Mosaic Screen Reveals Ecdysone-Responsive Genes Regulating Drosophila Oogenesis

open access: yesG3: Genes, Genomes, Genetics, 2016
Multiple aspects of Drosophila oogenesis, including germline stem cell activity, germ cell differentiation, and follicle survival, are regulated by the steroid hormone ecdysone.

Azadirachtin disrupts ecdysone signaling and alters sand fly immunity [PDF]

open access: yesParasites & Vectors
Background Leishmaniasis is a group of neglected vector-borne diseases transmitted by phlebotomine sand flies. Leishmania parasites must overcome various defenses in the sand fly midgut, including the insects’s immune response.

Nutritional control of body size through FoxO-Ultraspiracle mediated ecdysone biosynthesis [PDF]

open access: yeseLife, 2014
Despite their fundamental importance for body size regulation, the mechanisms that stop growth are poorly understood. In Drosophila melanogaster, growth ceases in response to a peak of the molting hormone ecdysone that coincides with a nutrition ...

Bicistronic Expression of Ecdysone-Inducible Receptors in Mammalian Cells

open access: yesBioTechniques, 2001
The recent emergence of inducible expression systems for mammalian cells has greatly facilitated the in vivo analysis of gene function. The ecdysone-inducible expression system is particularly attractive because of (i) extremely low basal expression and ...

Larval diapause termination in the bamboo borer, Omphisa fuscidentalis. [PDF]

open access: yesPLoS ONE, 2017
In insects, juvenile hormone (JH) and 20-hydroxyecdysone (20E) regulate larval growth and molting. However, little is known about how this cooperative control is terminating larval diapause especially in the bamboo borer, Omphisa fuscidentalis.
