Endocrine Disruptors Certain compounds are likely to act as endocrine disruptors not only by a direct binding to receptorsacting as hormone-mimics (agonists) or as antihormones (antagonists)but also indirectly by modulating endogenous hormone levels by interfering with biochemical processes associated with the production, availability, or metabolism of hormones or also by the modulation of receptors. 6. The type of endocrine product is determined by which tissue layer a gland originated in. 33. MF is secreted by the mandibular organ
There is some evidence that MF may have a role in larval development by acting as a hormone that retards development (a juvenilizing factor)
In adults, MF may function in a reproductive capacity. One of the most important lessons to be learned from the "TBT story" and its effects in mollusks is that EDCs may impact different levels of biological integrations from molecules to communities affecting also the survival of populations in the field. The invertebrates form all of the major divisions of the animal kingdom called phyla, with the exception of vertebrates.

Combines with specific insulin receptors on the surface of the cell membrane. The Endocrine System. Dr .Shantanu Jain Growth in Crustaceans Occurs through molting = ecdysis
Stages of molting
Proecdysis - preparation for molting
epidermal cells separate from the old cuticle (apolysis) and divide forming the new exoskeleton
Calcium removed from old exoskeleton
hepatopancreas - release of energy reserves from storage (animal stops feeding)
Ecdysis
shedding of the old exoskeleton
cuticle is soft - rapid uptake of water
Metecdysis
Mineral deposition into the new cuticle
Endocuticle formation
Feeding begins again
New tissue formation follows
Increased DNA and protein synthesis
tissue replaces water
Intermolt
As skeleton and tissue growth nears completion metabolism is shifted to storage of energy reserves into the hepatopancreas
Regulation of many processes is involved
Metabolism
Water /mineral balance
