1. The nature and cellular mechanisms that are responsible for endothelium-dependent relaxations resistant to indomethacin and NG-nitro-L-arginine methyl ester (L-NAME) were investigated in phenylephrine (PE) precontracted isolated carotid arteries from the rabbit. 2. In the presence of the cyclo-oxygenase inhibitor

Protein fatty-acylation is the covalent addition of a lipid chain at specific amino acids. This modification changes the inherent hydrophobicity of a protein, often targeting it to cellular membrane compartments. Acylation may also regulate protein activity, stability, and protein-protein interactions.

Sensitive and specific visualization of small biomolecules in living systems is highly challenging. We report stimulated Raman-scattering imaging of alkyne tags as a general strategy for studying a broad spectrum of small biomolecules in live cells and animals. We demonstrate

We examined the responses of newborn piglet pulmonary resistance arteries (PRAs) to 5,6-epoxyeicosatrienoic acid (5,6-EET), a cytochrome P-450 metabolite of arachidonic acid. In PRAs preconstricted with a thromboxane A(2) mimetic, 5,6-EET caused a concentration-dependent dilation. This dilation was partially inhibited
