Prostaglandins are synthesized from arachidonic acid by cyclooxygenase (COX)-1 or -2, which convert the acid into PGH₂. This is further processed by cytosolic or microsomal prostaglandin synthases to become PGE₂ or one of several other prostanoids. Prostacyclin is the major cyclooxygenase product in blood vessel walls and it is present in inflammatory fluids in similar concentrations to PGE₂.… » Read More

KEEPING YOUR ELEPHANTS HAPPY

A new longitudinal study from ISWE members.

A basic understanding of wildlife endocrinology is critical to ensure the health and welfare of endangered species. Hormone analysis is a widely accepted tool for monitoring reproductive function and responses to stressors in captive and free-ranging animals. Understanding… » Read More

The Id proteins (Inhibitors of DNA Binding/Differentiation) represent a family of dominant negative regulators of the basic helix-loop-helix transcription factors whose activities result in delayed cell differentiation and prolonged proliferation. The down-regulation of Id1 is necessary for differentiation to proceed in many cell lineages.… » Read More
