Glycogen synthase kinase 3 (GSK3) has been linked to the mechanisms of stress, mood regulation, and the effects of antidepressants. The functions of the GSK3β isoform have been extensively investigated, but little is known about the α-isoform, although they may functionally related. In a recently established modified swim test with a third delayed swim exposure, brain GSK3β mRNA expression positively correlated with floating behavior on the third test. A two-week-long pretreatment regime with imipramine (7...

Production of chemicals in microbes often employs potent biosynthetic enzymes, which can interact with the microbial native metabolism to affect cell fitness and product yield. However, production optimization largely relies on data collected from wild-type strains in the absence of metabolic perturbations, thus limiting their relevance to specific conditions. Here, we address this issue by coupling cell fitness to the production of thiamine diphosphate in Escherichia coli using a synthetic RNA biosensor. We use this strategy to interrogate a library of transposon mutants and elucidate the native gene network influencing both cell fitness and thiamine production...

OBJECTIVES: Thiamine serves as a cofactor for several enzymes involved in brain function and neurotransmitters biosynthesis. Thiamine-dependent enzymes are important for oxidant stress defenses. Several studies have reported that thiamine deficiency in the central nervous system reduces seizure threshold. The present study was designed to investigate the effect of acute and chronic administration of thiamine alone and in combination with sub-effective dose of diazepam on pentylenetetrazole (PTZ)-induced tonic-clonic seizures in mice...

The trafficking and delivery of sulfur to cofactors and nucleosides is a highly regulated and conserved process among all organisms. All sulfur transfer pathways have generally an L-cysteine desulfurase as initial sulfur-mobilizing enzyme in common, which serves as sulfur donor for the biosynthesis of sulfur-containing biomolecules like iron-sulfur (FeS) clusters, thiamine, biotin, lipoic acid, the molybdenum cofactor (Moco), and thiolated nucleosides in tRNA. The human L-cysteine desulfurase NFS1 and the Escherichia coli homologue IscS share an amino acid sequence identity of about 60%...

Wernicke's encephalopathy is a rare neurological disorder caused by thiamine deficiency, characterised by ocular motor dysfunction, ataxia and impairment in consciousness. It predominantly affects brain regions with a high metabolic rate such as mammillary bodies, medial thalamic nuclei, the tectal region and the cerebellum. Although chronic alcoholism is the most common cause of Wernicke's encephalopathy, various other conditions not related to alcohol consumption such as bariatric surgery, acute pancreatitis, hyperemesis gravidarum, prolonged fasting and gastrointestinal surgery have been implicated in its aetiology...

BACKGROUND: Fatigue is the most frequent and often debilitating symptom for patients with multiple sclerosis (MS). There are no available effective therapies for fatigue associated with MS, and it is unclear whether a successful therapy of MS leads to clinical improvement. Sulbutiamine is a lipophilic compound that crosses the blood-brain barrier more readily than thiamine and increases the levels of thiamine and thiamine phosphate esters in the brain. Whereas several clinical trials have demonstrated the beneficial effects of sulbutiamine in patients with asthenia, there have been no reports on the effects of sulbutiamine on fatigue in patients with MS...

Wernicke's encephalopathy (WE) is a disease caused by thiamine deficiency related to alcoholism, hyperemesis, or thiamine malabsorption. The clinical manifestations of WE are mental change, ataxia, and ophthalmoplegia. The typical magnetic resonance imaging (MRI) findings of WE are symmetrical involvement of medial thalamus, periventricular region of the third ventricle, periaqueductal area, and mammillary body. The atypical MRI findings are more common in nonalcoholic WE. Since the increasing population of obesity and the preference of weight loss surgery, the risk of developing thiamine deficiencies associated with weight loss surgery has become a considerable etiology of WE...

BACKGROUND: Sepsis refers the dysregulated host immune response elicited by microbial infections resulting in life-threatening organ dysfunction. Sepsis represents a medical challenge, since it is associated with a rate of death as high as 60%. Septic shock is strongly associated with vascular dysfunction and elevated pulmonary capillary permeability. We recently reported that the combination of hydrocortisone (HC), ascorbic acid (VitC) and thiamine dramatically improves outcomes and reduces mortality in septic patients...
