Mechanisms For The Environmental Regulation Of Gene Expression: Ecological Aspects Of Animal Development [PDF]

, 2005
The environment can play a significant role in the production of phenotypes. However, the developmental mechanisms by which the environmental agents effect normal development are Just becoming known. At least three paths have been found through which the

A Drosophila CRISPR/Cas9 Toolkit for Conditionally Manipulating Gene Expression in the Prothoracic Gland as a Test Case for Polytene Tissues

G3: Genes, Genomes, Genetics, 2018
Targeting gene function with spatial or temporal specificity is a key goal in molecular genetics. CRISPR-Cas9 has greatly facilitated this strategy, but some standard approaches are problematic.

Ecdysone promotes growth of imaginal discs through the regulation of Thor in D. melanogaster

Scientific Reports, 2015
Animals have a determined species-specific body size that results from the combined action of hormones and signaling pathways regulating growth rate and duration.

Stimulation of JNK Phosphorylation by the PTTH in Prothoracic Glands of the Silkworm, Bombyx mori

Frontiers in Physiology, 2018
In this study, phosphorylation of c-Jun N-terminal kinase (JNK) by the prothoracicotropic hormone (PTTH) was investigated in prothoracic glands (PGs) of the silkworm, Bombyx mori. Results showed that JNK phosphorylation was stimulated by the PTTH in time-

Effects of sublethal doses of methoxyfenozide on the development, survival and reproduction of Spodoptera frugiperda. [PDF]

, 2011
The lethal and sublethal effects of the ecdysone agonist methoxyfenozide on the fall armyworm, Spodoptera frugiperda (J. E. Smith), were investigated by feeding a methoxyfenozide-treated diet to ϐifth instars until pupation in doses corresponding to ...

Molecular characterization of the singed wings locus of Drosophila melanogaster. [PDF]

, 2011
BACKGROUND: Hormones frequently guide animal development via the induction of cascades of gene activities, whose products further amplify an initial hormonal stimulus.

Computational Binding Study Hints at Ecdysone 20-Mono-Oxygenase as the Hitherto Unknown Target for Ring C-Seco Limonoid-Type Insecticides

Molecules
The insecticidal property of ring C-seco limonoids has been discovered empirically and the target protein identified, but, to date, the molecular mechanism of action has not been described at the atomic scale.

In vitro cultures of pupal integumental explants to bioassay insect growth regulators with ecdysteroid activity for ecdysteroid amounts and cuticle secretion [PDF]

, 2007
The present study evaluated the in vitro bioassay with pupal integumental explants of the mealworm Tenebrio molitor to test the activity of two types of insect growth regulators (IGRs) with ecdysteroidal action. We assessed the imidazole derivative KK-42,
