The Cutting Edge of Endocrine Disrupter Research
5th Annual Symposium on the Environment and Hormones
October 16-18, 2003
Hosted by: Tulane/Xavier Center for Bioenvironmental Research
We contend that the phenomenon known as endocrine disruption
is a manifestation of a larger biological issue that is,
the complex signaling networks that exist within and between
organisms. These signaling networks can be maintained or perturbed
by environmental factors. At e.hormone we
intend to develop the tools for a new science of environmental
signaling and introduce participants to the Environmental
Signaling Network (an NSF-sponsored activity).
