For the first time a dual pathway for dephosphorylation of myo-inositol hexakisphosphate by a histidine acid phytase was established. The phytate-degrading enzyme of Klebsiella terrigena degrades myo-inositol hexakisphosphate by stepwise dephosphorylation, preferably via D-Ins(1,2,4,5,6)P5, D-Ins(1,2,5,6)P4, D-Ins(1,2,6)P3, D-Ins(1,2)P2 and alternatively via D-Ins(1,2,4,5,6)P5, Ins(2,4,5,6)P4, ...
Positional isomers of D-myo-inositol 1,4,5-trisphosphate (Ins(1,4,5)P3), Ins(1,4,6)P3, and Ins(1,3,6)P3 were examined to explore the roles for hydroxyl groups of Ins(1,4,5)P3, recognized by metabolic enzymes and by the receptor. Ins(1,4,6)P3 and Ins(1,3,6)P3 inhibited the dephosphorylation of [3H] Ins(1,4,5)P3 by the 5-phosphatase present in erythrocyte ghosts. The Ki value for the former compo...
OBJECTIVE Caspase-8 (CASP8) plays a central role in the apoptotic pathway and aberrant regulation of this pathway may cause cancers. Previous studies investigating the association between CASP8 -652 6N ins/del polymorphism and colorectal cancer (CRC) risk showed inconclusive results. We performed a meta-analysis of all available studies to investigate this association. METHODS All studies pub...
Antibodies against Ins(1,4,5)P3 were raised by immunizing rabbits with two types of InsP3-BSA conjugates which were synthesized by covalently coupling Ins(1,4,5)P3 to the carrier protein via alkyl linkages. The anti-Ins(1,4,5)P3 antibody was detected by a novel ELISA using Ins(1,4,5)P3-immobilized microtitre plates. Both antiserum preparations showed specific binding with Ins(1,4,5)P3, with tit...
RATIONALE Insulin (INS) resistance associated with hyperestrogenemias occurs in gestational diabetes mellitus, polycystic ovary syndrome, ovarian hyperstimulation syndrome, estrogen therapies, metabolic syndrome, and obesity. The mechanism by which INS and estrogen interact is unknown. We hypothesize that estrogen binds directly to INS and the insulin receptor (IR) producing INS resistance. O...
OBJECTIVE To evaluate the safety and effectiveness of triple therapy using insulin, metformin, and a thiazolidinedione following a course of dual therapy using insulin and metformin or insulin and a thiazolidinedione in type 2 diabetes. RESEARCH DESIGN AND METHODS Twenty-eight type 2 diabetic subjects using insulin monotherapy (baseline HbA(lc) level 8.5%) who had been randomly assigned to in...
Transplantation of GABAergic interneurons (INs) can provide long-term functional benefits in animal models of epilepsy and other neurological disorders. Whereas GABAergic INs can be differentiated from embryonic stem cells, alternative sources of GABAergic INs may be more tractable for disease modeling and transplantation. We identified five factors (Foxg1, Sox2, Ascl1, Dlx5, and Lhx6) that con...
Racemic mixtures and enantiomerically pure D-isomers of both myo-inositol 1,3,6-trisphosphorothioate [Ins(1,3,6)PS(3)] and myo-inositol 1,4,6-trisphosphorothioate [Ins(1,4,6)PS(3)], prepared by total synthesis, were examined in Ca(2+) flux and binding assays. Both D-Ins(1,3,6)PS(3) and D-Ins(1,4,6)PS(3) were shown to be low intrinsic activity partial agonists at the platelet myo-inositol 1,4, 5...
In bovine adrenal microsomes, Ins(1,4,5)P3 binds to a specific high-affinity receptor site (Kd = 11 nM) with low affinity for two other InsP3 isomers, Ins(1,3,4)P3 and Ins(2,4,5)P3. In the same subcellular fractions Ins(1,4,5)P3 was also the most potent stimulus of Ca2+ release of all the inositol phosphates tested. Of the many inositol phosphates recently identified in angiotensin-II-stimulate...
accuracy of inertial navigation system (ins) is limited by inertial sensors imperfections. before using inertial sensors signals in the data fusion algorithm, noise removal method should be performed, in which, wavelet decomposition method is used. in this method the raw data is decomposed into high and low frequency data sets. in this study, wavelet multi-level resolution analysis (wmra) techn...
