Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)Vitamin B 6: VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.Vitamin A: Retinol and derivatives of retinol that play an essential role in metabolic functioning of the retina, the growth of and differentiation of epithelial tissue, the growth of bone, reproduction, and the immune response.

Nicotinamide decreases MHC class II but not MHC class I expression and increases intercellular adhesion molecule-1 structures in non-obese diabetic mouse pancreas. (1/1693)

Pancreases of untreated and nicotinamide (NIC)-treated pre-diabetic (10-week-old) and overtly diabetic (25-week-old) female NOD (non-obese diabetic) mice and of NON (non-obese non-diabetic) control mice were studied, with the following results. (1) Islets and ducts of overtly diabetic untreated NOD mice (25-week-old) were found to express low levels of MHC class I and II molecules, like NON controls, and high levels of adhesive molecules. (2) NIC was able to slightly affect glycaemia and insulitis, slowing down diabetes progression. Moreover it significantly decreased MHC class II expression (but not class I) in vivo by week 10, and significantly enhanced intercellular adhesion molecule-1 (ICAM-1) expression, mainly by week 25, within the pancreas, where 5-bromo-2'-deoxyuridine positive nuclei and insulin positive cells were present, demonstrating that a stimulation of endocrine cell proliferation occurs. (3) In addition, NIC partly counteracted the fall of superoxide dismutase levels, observed in untreated diabetic NOD animals. (4) In vitro studies demonstrated that NIC: (i) was able to significantly reduce nitrite accumulation and to increase NAD+NADH content significantly, and (ii) was able to increase the levels of interleukin-4, a T helper 2 lymphocyte (Th2) protective cytokine, and of interferon-alpha (IFN-alpha), which is known to be able to induce MHC class I and ICAM-1 but not MHC class II expression, as well as IFN-gamma, which is also known to be able to induce MHC class I and ICAM-1 expression. The latter, although known to be a proinflammatory Th1 cytokine, has also recently been found to exert an anti-diabetogenic role. This study therefore clearly shows that adhesive mechanisms are ongoing during the later periods of diabetes in pancreatic ducts of NOD mice, and suggests they may be involved in a persistence of the immune mechanisms of recognition, adhesion and cytolysis and/or endocrine regeneration or differentiation processes, as both NIC-increased ICAM-1 expression and 5-bromo-2'-deoxyuridine positivity imply. The effects of NIC on MHC class II (i.e. a reduction) but not class I, and, mainly, on ICAM-1 expression (i.e. an increase), together with the increase in Th2 protective cytokine levels are very interesting, and could help to explain its mechanism of action and the reasons for alternate success or failure in protecting against type 1 diabetes development.  (+info)

Inhibitors of poly (ADP-ribose) synthetase protect rat cardiomyocytes against oxidant stress. (3/1693)

OBJECTIVE: Inhibitors of poly (ADP-ribose) synthetase (PARS) activity reduce the infarct size caused by regional myocardial ischaemia and reperfusion in the rabbit and rat in vivo. The mechanism of action of these inhibitors is unclear. Here we investigate the effects of the PARS inhibitor 3-aminobenzamide (3-AB) on infarct size caused by ischaemia and reperfusion of the isolated, perfused heart of the rat. We also investigate the role of PARS in the hydrogen peroxide-mediated cell injury/necrosis in rat cardiac myoblasts. METHODS: Rat isolated hearts perfused at constant pressure (80 mmHg) were subjected to 35 min of regional ischaemia and 2 h of reperfusion. Infarct size was determined at the end of the experiment using nitro-blue tetrazolium. 3-AB (300 microM) or 3-aminobenzoic acid (3-ABA, 300 microM) were infused during the reperfusion period. Rat cardiac myoblasts (H9c2 cells) were preincubated with the PARS inhibitors, 3-AB. nicotinamide (Nic) or 1,5-dihydroxyisoquinoline (ISO) or the inactive analogues 3-ABA or nicotinic acid (NicA) prior to exposure with hydrogen peroxide (1 mM). Cell injury was assessed by measuring mitochondrial respiration and cell necrosis by measuring the release of LDH. PARS activity was determined by measuring the incorporation of NAD into nuclear proteins. RESULTS: Regional ischaemia and reperfusion of the isolated rat heart resulted in an infarct size of 54% which was reduced by 3-AB, but not by 3-ABA. Exposure of rat cardiac myoblasts to hydrogen peroxide caused an increase in PARS activity and cell injury/necrosis which was attenuated by pretreatment with the PARS inhibitors. CONCLUSION: Inhibition of the activity of PARS attenuates the cell death associated with oxidant stress in rat cardiac myoblasts and heart.  (+info)

Nicotinamide inhibits sodium-dependent phosphate cotransport activity in rat small intestine. (4/1693)

BACKGROUND: We recently reported that the administration of niceritorol (a nicotinic acid derivative which improves lipid metabolism and peripheral circulation, and is used for the treatment of hyperlipidaemia and impaired peripheral circulation) to patients with hyperphosphataemia undergoing dialysis decreased the serum phosphate (Pi) concentration. We found that this was due to an acceleration of faecal Pi excretion by niceritrol. METHODS: Intestinal brush border membrane vesicles (BBMVs) were prepared from rat jejunum, and the Na+-dependent and Na+-independent Pi transport activities in these vesicles were measured. In addition, the functional Pi transporter from rat small intestine was injected in Xenopus oocytes, and the effect of nicotinamide on the levels of its expression were measured by northern blotting. RESULTS: The Na+-dependent component was significantly decreased in the BBMVs isolated from rats treated with nicotinamide, while the Na+-independent component was not changed. Kinetic studies demonstrated that the decreased activity was due to reduction of the Vmax value and not an elevation of the Km values. When poly(A)+RNA from rats treated with nicotinamide was microinjected into Xenopus oocytes, the Pi transport activity was significantly decreased compared with that in the control animals. In addition, there were no significant changes in Na/Pi cotransporters and activators, but the vitamin D receptor mRNA level was reduced to 80% of the control level. CONCLUSIONS: These observations suggest that nicotinamide may regulate the expression of a major functional Na/Pi cotransporter in the rat small intestine.  (+info)

Magnetic resonance detects metabolic changes associated with chemotherapy-induced apoptosis. (5/1693)

Apoptosis was induced by treating L1210 leukaemia cells with mechlorethamine, and SW620 colorectal cells with doxorubicin. The onset and progression of apoptosis were monitored by assessing caspase activation, mitochondrial transmembrane potential, phosphatidylserine externalization, DNA fragmentation and cell morphology. In parallel, 31P magnetic resonance (MR) spectra of cell extracts were recorded. In L1210 cells, caspase activation was detected at 4 h. By 3 h, the MR spectra showed a steady decrease in NTP and NAD, and a significant build-up of fructose 1,6-bisphosphate (F-1,6-P) dihydroxyacetonephosphate and glycerol-3-phosphate, indicating modulation of glycolysis. Treatment with iodoacetate also induced a build-up of F-1,6-P, while preincubation with two poly(ADP-ribose) polymerase inhibitors, 3-aminobenzamide and nicotinamide, prevented the drop in NAD and the build-up of glycolytic intermediates. This suggested that our results were due to inhibition of glyceraldehyde-3-phosphate dehydrogenase, possibly as a consequence of NAD depletion following poly(ADP-ribose) polymerase activation. Doxorubicin treatment of the adherent SW620 cells caused cells committed to apoptosis to detach. F-1,6-P was observed in detached cells, but not in treated cells that remained attached. This indicated that our observations were not cell line- or treatment-specific, but were correlated with the appearance of apoptotic cells following drug treatment. The 31P MR spectrum of tumours responding to chemotherapy could be modulated by similar effects.  (+info)

Neuroprotective effects of poly (ADP-ribose) polymerase inhibitors in transient focal cerebral ischemia of rats. (6/1693)

AIM: To explore the role of poly (ADP-ribose) polymerase (PARP) in focal cerebral ischemia with reperfusion injury. METHODS: Male Wistar rats underwent 3.5-h of temporary middle cerebral artery occlusion by intraluminal suture. Infarction volume was showed with 2,3,5-triphenyltetrazolium chloride (TTC) staining and quantitated by image analysis system, neurologic scores were determined with a 0-5 grading scale. RESULTS: 3-Aminobenzamide (3-AB) 10 mg.kg-1 or nicotinamide (Nic) at 20 mg.kg-1 showed potent neuroprotective effects within 0-6 h, neurologic deficits were attenuated. With the increasing dose of PARP inhibitors, beneficial effects were compromised, particularly, administration of Nic 60 mg.kg-1 at the onset of reperfusion drastically accelerated brain damage. Phytomenadione, a selective inhibitor of mono (ADP-ribosyl) transferase, had little effect on infarction volume. CONCLUSION: Transient incomplete inhibition of PARP provides a neuroprotective effects against cerebral ischemia-reperfusion injury, with a relatively wide therapeutic window, whereas severe inhibition of this enzyme, especially in reperfusion phase, is detrimental.  (+info)

Inhibitors of poly (ADP-ribose) synthetase protect rat proximal tubular cells against oxidant stress. (7/1693)

BACKGROUND: The generation of reactive oxygen species (ROS) has been implicated in the pathogenesis of renal ischemia-reperfusion injury. ROS produce DNA strand breaks that lead to the activation of the DNA-repair enzyme poly (ADP-ribose) synthetase (PARS). Excessive PARS activation results in the depletion of its substrate, nicotinamide adenine dinucleotide (NAD) and subsequently of adenosine 5'-triphosphate (ATP), leading to cellular dysfunction and eventual cell death. The aim of this study was to investigate the effect of various PARS inhibitors on the cellular injury and death of rat renal proximal tubular (PT) cells exposed to hydrogen peroxide (H2O2). METHODS: Rat PT cell cultures were incubated with H2O2 (1 mM) either in the presence or absence of the PARS inhibitors 3-aminobenzamide (3-AB, 3 mM), 1,5-dihydroxyisoquinoline (0.3 mM) or nicotinamide (Nic, 3 mM), or increasing concentrations of desferrioxamine (0.03 to 3 mM) or catalase (0.03 to 3 U/ml). Cellular injury and death were determined using the MTT and lactate dehydrogenase (LDH) assays, respectively. H2O2-mediated PARS activation in rat PT cells and the effects of PARS inhibitors on PARS activity were determined by measurement of the incorporation of [3H]NAD into nuclear proteins. RESULTS: Incubation of rat PT cells with H2O2 significantly inhibited mitochondrial respiration and increased LDH release, respectively. Both desferrioxamine and catalase reduced H2O2-mediated cellular injury and death. All three PARS inhibitors significantly attenuated the H2O2-mediated decrease in mitochondrial respiration and the increase in LDH release. Incubation with H2O2 produced a significant increase in PARS activity that was significantly reduced by all PARS inhibitors. 3-Aminobenzoic acid (3 mM) and nicotinic acid (3 mM), structural analogs of 3-AB and Nic, respectively, which did not inhibit PARS activity, did not reduce the H2O2-mediated injury and necrosis in cultures of rat PT cells. CONCLUSION: We propose that PARS activation contributes to ROS-mediated injury of rat PT cells and, therefore, to the cellular injury and cell death associated with conditions of oxidant stress in the kidney.  (+info)

Accelerated radiotherapy, carbogen, and nicotinamide in glioblastoma multiforme: report of European Organization for Research and Treatment of Cancer trial 22933. (8/1693)

PURPOSE: A three-step phase I/II trial associating accelerated radiotherapy with carbogen (step 1, ARCO), with nicotinamide (step 2, ARN), or with both (step 3, ARCON) was conducted, the aim of which was to overcome the effects of proliferation and hypoxia as potential causes of tumor radioresistance in glioblastoma multiforme. PATIENTS AND METHODS: Radiotherapy consisted of 60 Gy delivered over 4 weeks in 1.5-Gy fractions twice daily, 5 days a week. Carbogen breathing was started 5 minutes before each fraction and continued until the end of each treatment session. Nicotinamide was given daily as a single oral dose of 85 mg/kg. RESULTS: A total of 115 patients with a median age of 55 years were registered. Of 107 eligible patients, 23 were registered in step 1, 28 in step 2, and 56 in step 3. The planned treatment was administered without any interruption in 72% of patients (86% in ARCO but 68% in ARN and ARCON). The incidence and severity of acute skin and mucous membrane toxicity were higher in patients who received nicotinamide (ie, the ARN and ARCON groups). Grade 1 to 2 gastrointestinal toxicity was observed in 44% of patients in the ARN group and 32% of patients in the ARCON group, but only in 8% of patients in the ARCO group. Eight percent of evaluated patients presented with abnormal liver test results at treatment completion. The dose of corticosteroids had to be increased in 44% of patients. Late neurologic side effects were similar in all treatment steps and were observed mostly in patients with disease progression. Median survival times for patients treated with ARCO, ARN, and ARCON were 10.1, 9.7, and 11.1 months, respectively. CONCLUSION: Feasibility of ARCO treatment was good but that of ARN and ARCON was only fair. This probably reflected the higher acute toxicity rate, particularly gastrointestinal, for patients receiving nicotinamide. The dose of corticosteroids had to be increased frequently during treatment, suggesting a higher than expected acute neurologic toxicity. Overall survival was similar in the three treatment steps and not different when compared with results of other series that used radiotherapy alone.  (+info)
