Cyclic Amp and Folic Acid Mediated Cyclic Gmp Accumulation In
In a suitable environment spores of the Dictyostelia [ 1 ] germinate yielding small amoebae. Each amoebae feeds on bacteria and divides. Following consumption of the food supply amoebae aggregate forming a slug where cells differentiate into spores and stalk ceils. The orientation of cells towards a food source or an aggregation center is guided by gradients of concentration of chemotactic mole...
متن کاملThe pace Maker of the Cardiac Ganglion of Limulus .polyphemus
The ganglion on the dorsal surface of the heart of Limulus polyphemus originates the impulses which cause the contractions of the cardiac muscle (1). In large specimens the portion of the dorsal nerve cord which contains the ganglion cells may be 10 or even 12 cm. in length and one naturally wonders where in the extent of this long structure the impulse actually arises. Does it arise in a speci...
متن کاملRole of phospholamban in cyclic GMP mediated signaling in cardiac myocytes.
We tested the hypothesis that the negative functional effects of cyclic GMP on cardiac myocytes were mediated through phospholamban (PLB) and activation of sarcoplasmic reticulum Ca(2+)-ATPase. Using ventricular myocytes from wild type (WT, n=10) and PLB knockout (PLB-KO, n=10) mouse hearts, functional changes were measured using a video edge detector at baseline and after 10(-6), 10(-5)M 8-bro...
متن کاملGuanylin peptides: renal actions mediated by cyclic GMP.
The guanylin family of cGMP-regulating peptides has three subclasses of peptides containing either three intramolecular disulfides found in bacterial heat-stable enterotoxins (ST), or two disulfides observed in guanylin and uroguanylin, or a single disulfide exemplified by lymphoguanylin. These small, heat-stable peptides bind to and activate cell-surface receptors that have intrinsic guanylate...
متن کاملInward currents and increases in cytosolic Ca2+ concentration induced by cyclic ADP-ribose in turtle olfactory receptor cells.
In olfactory receptor cells, it is well established that cyclic AMP (cAMP) and inositol-1,4,5-trisphosphate (IP(3)) act as second messengers during odor responses. In previous studies, we have shown that cAMP-increasing odorants induce odor responses even after complete desensitization of the cAMP-mediated pathway. These results suggest that at least one cAMP-independent pathway contributes to ...
