cyclic guanosine 3 5 monophosphate/diarrhea

Intracellular communication and transmission of messages for many hormones and free radicals occur after the hormones and free radicals bind to their receptors by enhancing the activity of guanylate cyclase, the enzyme that catalyzes the conversion of guanosine triphosphate to the intracellular

Several trivalent cations, including lanthanum (La3+), inhibited the secretion (enterosorption) induced by the enterotoxins of Vibrio cholerae and Escherichia coli in the rabbit ileum in vivo. High concentrations (greater than 10 mM) of La3+ were required to inhibit cholera enterotoxin (CE)-induced

Guanylin, uroguanylin, and the bacterial heat-stable enterotoxin (ST) peptides comprise a new family of cyclic guanosine 3'-5' monophosphate (cGMP)-regulating agonists. The discovery of guanylin and uroguanylin peptides stems from studies of cellular mechanisms underlying a form of secretory

The regulation of intestinal salt and water transport is critical to the maintenance of fluid volume. Control of this life-sustaining activity is mediated by the concerted actions of hormones, neurotransmitters, and locally acting factors. Guanylin and uroguanylin are novel peptides that were first

BACKGROUND Many enterotoxigenic Escherichia coli strains produce the heat-stable toxin, STa, which, by activation of the intestinal receptor-enzyme guanylyl cyclase (GC) C, triggers an acute, watery diarrhea. We set out to identify GCC inhibitors that may be of benefit for the treatment of
