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

G3: 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.

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

eLife, 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 ...

Impact of steroid hormone signals on Drosophila cell cycle during development [PDF]

Cell Division, 2009
Metamorphosis of Drosophila involves proliferation, differentiation and death of larval tissues in order to form the adult fly. The major steroid hormone implicated in the larval-pupal transition and adult tissue modelling is ecdysone.

Effects of Dietary Calcium and Magnesium Levels on the Growth Performance, Tissue Mineral Deposition, Exoskeleton Development, and Molting Performance of Chinese Mitten Crab (<i>Eriocheir sinensis</i>). [PDF]

Aquac Nutr
Calcium and magnesium are essential mineral elements for animal growth and development, playing crucial roles in skeletal formation, particularly in the molting process of crustaceans. However, their interaction is still poorly elucidated. This study investigated the effects of dietary calcium and magnesium levels on the growth performance, tissue ...

Mapping molluscan endocrinology: a systematic and critical appraisal. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Resource Availability Modulates Gene Expression Across Life Stages in a Migratory Butterfly. [PDF]

Mol Ecol
ABSTRACT Natural populations are in constant need of balancing resource allocation to compensate for seasonal environmental variation. In many insects, a well‐established trade‐off between migration and reproduction exists. While this trade‐off has been characterised phenotypically for decades, the underlying regulatory pathways are poorly understood ...

Spider Hemocyanin Binds Ecdysone and 20-OH-Ecdysone [PDF]

Journal of Biological Chemistry, 1999
Fluorescence quenching studies and binding experiments with [(3)H]ecdysone reveal that the respiratory protein, hemocyanin, of the tarantula Eurypelma californicum binds ecdysone. The binding constant for ecdysone ranges between 0.5 and 5 mM, indicating a low affinity binding.

Ecdysone Elicits Chronic Renal Impairment via Mineralocorticoid-Like Pathogenic Activities

Cellular 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 ecdysone receptor regulates several key physiological factors in Anopheles funestus

Malaria Journal, 2022
Background Malaria is a devastating disease, transmitted by female Anopheles mosquitoes infected with Plasmodium parasites. Current insecticide-based strategies exist to control the spread of malaria by targeting vectors.
