Correlated effects of ecdysone and neurosecretion in puparium formation (pupariation) of flies.

Proceedings of the National Academy of Sciences of the United States of America

Zdarek J, Fraenkel G.
PMID: 16591794
Proc Natl Acad Sci U S A. 1969 Oct;64(2):565-72. doi: 10.1073/pnas.64.2.565.

A neurohormone accelerates the formation and tanning of the fly puparium in the presence of ecdysone. When larvae of Phormia regina are divided by ligation into two parts before the critical period, the hind part remains untanned, unless injected...

Molecular biology of amphibian metamorphosis A new approach to an old problem.

Trends in endocrinology and metabolism: TEM

Shi YB.
PMID: 18407183
Trends Endocrinol Metab. 1994 Jan-Feb;5(1):14-20. doi: 10.1016/1043-2760(94)90116-3.

Amphibian metamorphosis has attracted the interest of developmental biologists for decades. Its dependency on thyroid hormone (TH) makes it a unique system to study postembryonic organ development as well as hormone action. Recent cloning o f the TH receptors...

Activation of the Drosophila hsp27 promoter by heat shock and by ecdysone involves independent and remote regulatory sequences.

The EMBO journal

Riddihough G, Pelham HR.
PMID: 16453691
EMBO J. 1986 Jul;5(7):1653-8.

Transcription of the Drosophila hsp27 gene is induced both by heat shock and by the steroid hormone ecdysone. Deletion analysis of the promoter using a transient expression assay in Drosophila tissue culture cells reveals two separate and functionally independent...

cDNA clones for the ecdysone-inducible polypeptide (EIP) mRNAs of Drosophila Kc cells.

The EMBO journal

Savakis C, Koehler MM, Cherbas P.
PMID: 16453496
EMBO J. 1984 Jan;3(1):235-43.

The ecdysone-inducible polypeptides (EIPs) 28, 29 and 40 were identified previously as polypeptides whose synthesis is stimulated early in the ecdysone response of Drosophila Kc cells. We have now shown, using two-dimensional gels, that each of these EIPs consists...

Ecdysone as regulator of inducible gene expression in Mammalian cells.

Mechanisms regulating nutrition-dependent developmental plasticity through organ-specific effects in insects.

Frontiers in physiology

Koyama T, Mendes CC, Mirth CK.
PMID: 24133450
Front Physiol. 2013 Sep 26;4:263. doi: 10.3389/fphys.2013.00263.

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. For instance, nutrition induces a disproportionate increase in the size of male horns in dung...

DETERMINANTS OF LARVAL MOLT INITIATION IN THE TOBACCO HORNWORM, MANDUCA SEXTA.

The Biological bulletin

Safranek L, Williams CM.
PMID: 29320264
Biol Bull. 1984 Dec;167(3):568-578. doi: 10.2307/1541410.

Hornworm larvae adhere to Dyar's rule under normal growth conditions, increasing their live weight by an average of 5- to 6-fold from the outset of one instar to the next. This adherence to Dyar's rule is largely maintained even...

The GPCR membrane receptor, DopEcR, mediates the actions of both dopamine and ecdysone to control sex pheromone perception in an insect.

Frontiers in behavioral neuroscience

Abrieux A, Duportets L, Debernard S, Gadenne C, Anton S.
PMID: 25309365
Front Behav Neurosci. 2014 Sep 12;8:312. doi: 10.3389/fnbeh.2014.00312. eCollection 2014.

Olfactory information mediating sexual behavior is crucial for reproduction in many animals, including insects. In male moths, the macroglomerular complex (MGC) of the primary olfactory center, the antennal lobe (AL) is specialized in the treatment of information on the...

New reporter gene assays for detecting natural and synthetic molting hormone agonists using yeasts expressing ecdysone receptors of various insects.

FEBS open bio

Ito-Harashima S, Matsuura M, Kawanishi M, Nakagawa Y, Yagi T.
PMID: 28680812
FEBS Open Bio. 2017 Jun 05;7(7):995-1008. doi: 10.1002/2211-5463.12239. eCollection 2017 Jul.

Synthetic nonsteroidal ecdysone agonists, a class of insect growth regulators (IGRs), target the ecdysone receptor (EcR), which forms a heterodimer with ultraspiracle (USP) to transactivate ecdysone response genes. These compounds have high binding affinities to the EcR-USP complexes of...

Halloween genes in panarthropods and the evolution of the early moulting pathway in Ecdysozoa.

Royal Society open science

Schumann I, Kenny N, Hui J, Hering L, Mayer G.

R Soc Open Sci. 2018 Sep 12;5(9):180888. doi: 10.1098/rsos.180888. eCollection 2018 Sep.

Moulting is a characteristic feature of Ecdysozoa-the clade of moulting animals that includes the hyperdiverse arthropods and less speciose groups, such as onychophorans, tardigrades and nematodes. Moulting has been best analysed in arthropods, specifically in insects and crustaceans, in...

Temporal Coordination of Collective Migration and Lumen Formation by Antagonism between Two Nuclear Receptors.

During development, cells undergo multiple, distinct morphogenetic processes to form a tissue or organ, but how their temporal order and time interval are determined remain poorly understood. Here we show that the nuclear receptors E75 and DHR3 regulate the...
