Extracellular matrix induced by steroids and aging through a G-protein-coupled receptor in a Drosophila model of renal fibrosis

open access: yesDisease Models & Mechanisms, 2020
Aldosterone is produced by the mammalian adrenal cortex to modulate blood pressure and fluid balance; however, excessive, prolonged aldosterone promotes fibrosis and kidney failure.

Structure of the heterodimeric ecdysone receptor DNA-binding complex [PDF]

open access: yesThe EMBO Journal, 2003
Ecdysteroids initiate molting and metamorphosis in insects via a heterodimeric receptor consisting of the ecdysone receptor (EcR) and ultraspiracle (USP). The EcR-USP heterodimer preferentially mediates transcription through highly degenerate pseudo-palindromic response elements, resembling inverted repeats of 5'-AGGTCA-3' separated by 1 bp (IR-1). The

Genomic Analysis of Drosophila Neuronal Remodeling: A Role for the RNA-Binding Protein Boule as a Negative Regulator of Axon Pruning [PDF]

open access: yes, 2008
Drosophila mushroom body (MB) {gamma} neurons undergo axon pruning during metamorphosis through a process of localized degeneration of specific axon branches.

Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]

open access: yes, 2014
Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

Pigment dispersing factor regulates ecdysone biosynthesis via bombyx neuropeptide G protein coupled receptor-B2 in the prothoracic glands of Bombyx mori. [PDF]

open access: yesPLoS ONE, 2014
Ecdysone is the key hormone regulating insect growth and development. Ecdysone synthesis occurs in the prothoracic glands (PGs) and is regulated by several neuropeptides.

Effects of methoxyfenozide on ecdysone receptor complex expression in larval Asian gypsy moth

open access: yesOpen Life Sciences, 2015
As a target of insect growth regulators, the ecdysone receptor complex binds ecdysone agonists to regulate gene transcription, development, and growth.

Dietary cholesterol promotes growth and ecdysone signalling pathway by modulating cholesterol transport in swimming crabs (Portunus trituberculatus)

open access: yesAnimal Nutrition, 2022
Cholesterol, as an indispensable nutrient, regulates molting and growth in crustacean. As crustaceans are unable to biosynthesize cholesterol de novo, it is central to understand how dietary cholesterol affects molting in crustaceans.

Ash2 acts as an ecdysone receptor coactivator by stabilizing the histone methyltransferase Trr. [PDF]

open access: yes, 2013
The molting hormone ecdysone triggers chromatin changes via histone modifications that are important for gene regulation. On hormone activation, the ecdysone receptor (EcR) binds to the SET domain-containing histone H3 methyltransferase trithorax-related

A critical role for ecdysone response genes in regulating egg production in adult female Rhodnius prolixus.

open access: yesPLoS ONE, 2023
Ecdysteroids control ovary growth and egg production through a complex gene hierarchy. In the female Rhodnius prolixus, a blood-gorging triatomine and the vector of Chagas disease, we have identified the ecdysone response genes in the ovary using ...
