Ovarian development plays an important role in the life history of insects and is crucial for control of the insect population. The metamorphosis of an insect is precisely regulated by the interaction of the juvenile hormone and ecdysone.

Transcriptional control of steroid biosynthesis genes in the Drosophila prothoracic gland by ventral veins lacking and knirps. [PDF]
Specialized endocrine cells produce and release steroid hormones that govern development, metabolism and reproduction. In order to synthesize steroids, all the genes in the biosynthetic pathway must be coordinately turned on in steroidogenic cells.

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]
Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

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 ...

Function and Evolution of Nuclear Receptors in Environmental-Dependent Postembryonic Development
Nuclear receptors (NRs) fulfill key roles in the coordination of postembryonal developmental transitions in animal species. They control the metamorphosis and sexual maturation in virtually all animals and by that the two main environmental-dependent ...

How collective cell migration starts and stops is a fundamental question but remains poorly understood. This review discusses the distinct mechanisms in in vivo models and cancer metastasis that define the regulatory pathways and collective features governing the initiation and termination of collective cell migration.

Steroid Control of Longevity in Drosophila melanogaster [PDF]
Ecdysone, the major steroid hormone of Drosophila melanogaster, is known for its role in development and reproduction. Flies that are heterozygous for mutations of the ecdysone receptor exhibit increases in life-span and resistance to various stresses ...

Bicistronic Expression of Ecdysone-Inducible Receptors in Mammalian Cells
The recent emergence of inducible expression systems for mammalian cells has greatly facilitated the in vivo analysis of gene function. The ecdysone-inducible expression system is particularly attractive because of (i) extremely low basal expression and ...
