2010 journal article
Interactions of the crustacean nuclear receptors HR3 and E75 in the regulation of gene transcription
GENERAL AND COMPARATIVE ENDOCRINOLOGY, 167(2), 268–278.
author keywords: Daphnia pulex; Ecdysteroids; Endocrine disruptor; Nuclear receptors
TL;DR:
The premise that HR3 is a major component of ecdysteroid signaling in some crustaceans and is under the negative regulatory control of E75 is supported.

2010 journal article
Intracellular Conversion of Environmental Nitrate and Nitrite to Nitric Oxide with Resulting Developmental Toxicity to the Crustacean Daphnia magna
PLoS ONE, 5(8), e12453.
Ed(s): X. Pan
MeSH headings : Animals; Animals, Newborn; Daphnia / cytology; Daphnia / drug effects; Daphnia / growth & development; Daphnia / metabolism; Drosophila / cytology; Drosophila / drug effects; Drosophila / metabolism; Ecdysteroids / metabolism; Ecosystem; Endocrine System / drug effects; Endocrine System / metabolism; Environmental Monitoring; Environmental Pollutants / metabolism; Environmental Pollutants / toxicity; Female; Intracellular Space / drug effects; Intracellular Space / metabolism; Nitrates / metabolism; Nitrates / toxicity; Nitric Oxide / metabolism; Nitrites / metabolism; Nitrites / toxicity; Reproduction / drug effects; Risk
TL;DR:
Results demonstrate that nitrite elicits developmental and reproductive toxicity at environmentally relevant concentrations due likely to its intracellular conversion to nitric oxide.

2010 journal article
Regulation and dysregulation of vitellogenin mRNA accumulation in daphnids (Daphnia magna)
AQUATIC TOXICOLOGY, 101(2), 351–357.
author keywords: Vitellogenin; Water flea; Biomarker; Ecdysteroids; Estrogens; Endocrine disruption
MeSH headings : Animals; Cadmium / toxicity; Daphnia / drug effects; Daphnia / genetics; Daphnia / metabolism; Ecdysteroids / toxicity; Ecdysterone / toxicity; Environmental Pollutants / toxicity; Estrogens / toxicity; Gene Expression / drug effects; Heterocyclic Compounds / toxicity; Polycyclic Compounds / toxicity; RNA, Messenger / metabolism; Vitellogenins / genetics; Vitellogenins / metabolism; Xenobiotics / toxicity
TL;DR:
Results indicate that ecdysteroids are suppressors of vitellogenin gene expression and that viteLLogenin mRNA levels can be elevated or suppressed in daphnids by xenobiotics that elicit antiecdysteroidal or ecdystersoidal activity, respectively.

2009 journal article
Expression and ecdysteroid responsiveness of the nuclear receptors HR3 and E75 in the crustacean Daphnia magna
MOLECULAR AND CELLULAR ENDOCRINOLOGY, 315(1-2), 208–218.
author keywords: Nuclear receptor; Water flea; Molting; Ecdysis; Endocrine disruption
MeSH headings : Amino Acid Sequence; Animals; Base Sequence; Crustacea / genetics; Crustacea / physiology; Daphnia / genetics; Daphnia / physiology; Drosophila melanogaster / genetics; Ecdysteroids / metabolism; Ecdysterone / metabolism; Female; Gene Expression Profiling; Gene Expression Regulation, Developmental; Humans; Molecular Sequence Data; Receptors, Cytoplasmic and Nuclear / genetics; Receptors, Cytoplasmic and Nuclear / metabolism; Sequence Alignment; Signal Transduction / physiology
TL;DR:
Results are consistent with the premise that transcription of HR3 is regulated by ecdysteroids in the crustacean D. magna and that HR3 likely serves as a mediator of Ecdysteroid regulatory action in crustaceans.
