Juvenile hormone regulates body size and perturbs insulin signaling in Drosophila [PDF]

open access: yes, 2014
The role of juvenile hormone (JH) in regulating the timing and nature of insect molts is well-established. Increasing evidence suggests that JH is also involved in regulating final insect size.

microRNA-14 as an efficient suppressor to switch off ecdysone production after ecdysis in insects

open access: yesRNA Biology, 2019
The precise increase and decrease of hormone ecdysone are critical for accurate development in insects. Most previous works focus on transcriptional activation of ecdysone production; however, little is known about the mechanism of switching off ecdysone

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Unexpected role of the steroid-deficiency protein ecdysoneless in pre-mRNA splicing. [PDF]

open access: yesPLoS Genetics, 2014
The steroid hormone ecdysone coordinates insect growth and development, directing the major postembryonic transition of forms, metamorphosis. The steroid-deficient ecdysoneless1 (ecd1) strain of Drosophila melanogaster has long served to assess the ...

Mechanisms regulating nutrition-dependent developmental plasticity through organ-specific effects in insects [PDF]

open access: yes, 2013
Nutrition, via the insulin/insulin-like growth factor (IIS)/Target of Rapamycin (TOR) signaling pathway, can provide a strong molding force for determining animal size and shape.

Distinct microRNA and mRNA responses elicited by ecdysone, diapause hormone and a diapause hormone analog at diapause termination in pupae of the corn earworm, Helicoverpa zea.

open access: yesGeneral and Comparative Endocrinology, 2019
Ecdysone, diapause hormone and a diapause hormone analog are all capable of breaking pupal diapause and prompting initiation of adult development in the cotton earworm, Helicoverpa zea.

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.

Inducible, reversible, and stable RNA interference in mammalian cells [PDF]

open access: yes, 2004
RNA interference is a powerful genetic approach for efficiently silencing target genes. The existing method of gene suppression by the constitutive expression of short hairpin RNAs (shRNAs) allows analysis of the consequences of stably silencing genes ...

Dpp regulates autophagy-dependent midgut removal and signals to block ecdysone production

open access: yesCell Death and Differentiation, 2018
Animal development and homeostasis require the programmed removal of cells. Autophagy-dependent cell deletion is a unique form of cell death often involved in bulk degradation of tissues.

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...
