Synthesis of myo-inositol is crucial in multicellular eukaryotes for production of phosphatidylinositol and inositol phosphate signaling molecules. The myo-inositol monophosphatase (IMP) enzyme is required for the synthesis of myo-inositol, breakdown of inositol (1,4,5)-trisphosphate, a second messenger involved in Ca(2+) signaling, and synthesis of L-galactose, a precursor of ascorbic acid. Tw...

The six-carbon polyol inositol is a uniquely versatile compound in biology. Myo-inositol is the major naturally occurring isomer of nine possible inositol isomers and is critical for the phosphoinositide (PI) cycle as a substrate for PI synthase (Berridge and Irvine 1989). Benjamins and Agranoff (1969) reported that epi-inositol is not a substrate for PI synthase, but a number of experiments su...

With the increasing use of organic resource for P fertilization, adsorption and desorption dynamics various phosphorus (OP) forms remain an important gap knowledge to bridge in order improve availability. In this study, we examined OP (myo-inositol hexakisphosphate, myo-IHP; glycerophosphate, GLY; glucose-6-phosphate, G6P) compounds from several soil minerals including Fe Al oxides (goethite gi...

OBJECTIVE The detection of early graft failure following coronary artery bypass grafting (CABG) enables immediate reintervention and may significantly limit myocardial damage, thus potentially improving outcome. To date, non-invasive indicators of early graft failure following coronary surgery are still of uncertain diagnostic value. METHODS In a prospective study, patients following isolated...

Six bifunctional molecules containing biotin and various inositol phosphates were synthesized. These compounds were designed on the basis of X-ray structures of the complexes of D-myo-inositol 1,4,5-triphosphates (IP(3)) and phospholipase C delta pleckstrin homology domain (PLCdelta PH) considering the application to the biotin-avidin techniques. The building blocks of the inositol moiety were ...

Myo-inositol was given orally to nine multiple sclerosis patients and nine healthy control subjects. Pattern reversal evoked potential testing was used to assess its effect. The principal positive wave increased in amplitude, duration and area in a dose-dependent manner in the multiple sclerosis group compared with controls. Cerebrospinal fluid concentrations of myo-inositol in multiple scleros...

Fluorescent timers are useful tools for studying the spatial and temporal cellular or molecular events. Based on the trans-splicing mechanism in Caenorhabditis elegans, we constructed a "fluorescent timer" through bicistronic expression of two fluorescent proteins with different maturation times. When used in vivo, this "timer" changes its color over time and therefore can be used to monitor th...
