Polyunsaturated fatty acids mobilize intracellular Ca2+ in NT2 human teratocarcinoma cells by causing release of Ca2+ from mitochondria.

In a variety of disorders, overaccumulation of lipid in nonadipose tissues, including the heart, skeletal muscle, kidney, and liver, is associated with deterioration of normal organ function, and is accompanied by excessive plasma and cellular levels of free fatty acids (FA). Increased concentrations of FA may lead to defects in mitochondrial function found in diverse diseases. One of the most ...

Nucleotide-induced mucin release from primary hamster tracheal surface epithelial cells involves the P2u purinoceptor.

Mucin release by airway surface epithelial cells is regulated by extracellular adenosine triphosphate (ATP) via a P2 purinoceptor-mediated mechanism. The objective of the present experiment was to examine the possible involvement of uridine triphosphate (UTP) in this purinergic signal transduction pathway. Using primary hamster tracheal surface epithelial cells, ATP and UTP were compared in the...

Characterization of the Arabidopsis heterotrimeric G protein.

We have used fluorescence resonance energy transfer and co-immunoprecipitation to analyze the interactions among the alpha, beta, and gamma1 subunits of the Arabidopsis heterotrimeric G protein. Using cyan and yellow fluorescent protein fusion constructs, we show that overexpressed Ggamma1 localizes to protoplast membranes, but Gbeta exhibits membrane localization only when the Ggamma1 protein ...

Human phosphatidylethanolamine-binding protein facilitates heterotrimeric G protein-dependent signaling.

In this study we report that human phosphatidylethanolamine-binding protein (hPBP) facilitates heterotrimeric G protein-coupled signaling. In Xenopus laevis oocytes, coexpression of hPBP with human mu opioid receptor, human delta opioid receptor, or human somatostatin receptor 2 evoked an agonist-induced increase in potassium conductance of G protein-activated inwardly rectifying potassium chan...
