Pulmonary arterial hypertension (PAH) is a debilitating and deadly disease with no known cure. Heart failure is a major comorbidity and a common cause of the premature death of patients with PAH. Increased asymmetrical right ventricular hypertrophy and septal wall thickening compress the left ventricular cavity and elicit diastolic heart failure. In this study, we used the Sugen5416/hypoxia/nor...

Glucose-6-phosphate dehydrogenase (G6PD) is the key enzyme that initiates pentose phosphate cycle in glucose metabolism. Physiologically, this pathway main source of nicotinamide adenine dinucleotide (NADPH) for red blood cells. This study aims to identify glucose-6-phosphate mutations Nung ethnic patients with G6PD deficiency. 18 pediatric group were diagnosed deficiency at Vietnam National Ch...

When Escherichia coli K-12 was grown on gamma-aminobutyrate, a second succinic semialdehyde dehydrogenase, dependent upon oxidized nicotinamide adenine dinucleotide or oxidized nicotinamide adenine dinucleotide phosphate and distinct from that induced by gamma-aminobutyrate, was gratuitously induced by succinic semialdehyde.

Microinjection of human Jurkat T-lymphocytes with nicotinic acid adenine dinucleotide phosphate (NAADP 1 ) dose-dependently stimulated intracellular Ca 2 1 -signaling. At a concentration of 10 nM NAADP 1 evoked repetitive and long-lasting Ca 2 1 oscillations of low amplitude, whereas at 50 and 100 nM, a rapid and high initial Ca 2 1 -peak followed by trains of smaller Ca 2 1 -oscillations was o...

Nicotiniamide adenine dintucleotide plhosphate-specific isocitrate dehydrogenase was extracted from etiolated pea (Pisurn satirum L.) seedlings and was purified 65-fold. The puirified enzyme exhibits one predoniinant protein band by pol acrylamide gel electrophoresis, w-hich corresponds to tiie dehy-drogenase activity as imieasuired by the nitro bluie tetrazolium technique. The reaction is read...

Cyclic ADP-ribose and nicotinic acid adenine dinucleotide phosphate were discovered >2 decades ago. That they are second messengers for mobilizing Ca(2+) stores has since been firmly established. Separate stores and distinct Ca(2+) channels are targeted, with cyclic ADP-ribose acting on the ryanodine receptors in the endoplasmic reticulum, whereas nicotinic acid adenine dinucleotide phosphate m...

Soluble cell-free extracts of actinomycete S4 grown on media containing mevalonate catalyze acetoacetate formation from mevalonate, mevaldate, and beta-hydroxy-beta-methylglutaryl-coenzyme A (CoA). Conversion of mevalonate to acetoacetate involves formation of free beta-hydroxy-beta-methylglutaryl-CoA, but not free mevaldate. The reaction favors mevalonate oxidation, and nicotinamide adenine di...
