Stable Isotope Dilution Assays for Clinical Analyses of Folates and Other One-Carbon Metabolites: Application to Folate-Deficiency Studies. [PDF]

open access: yesPLoS ONE, 2016
Folate deficiency is generally accepted as a potential direct or indirect risk factor for diseases including spina bifida, coronary heart diseases, malfunctions of the central nervous system, and cancer. The direct inclusion of folates in the methylation

Genetic screening reveals phospholipid metabolism as a key regulator of the biosynthesis of the redox-active lipid coenzyme Q

open access: yesRedox Biology, 2021
Mitochondrial energy production and function rely on optimal concentrations of the essential redox-active lipid, coenzyme Q (CoQ). CoQ deficiency results in mitochondrial dysfunction associated with increased mitochondrial oxidative stress and a range of

GSNOR Contributes to Demethylation and Expression of Transposable Elements and Stress-Responsive Genes

open access: yesAntioxidants, 2021
In the past, reactive nitrogen species (RNS) were supposed to be stress-induced by-products of disturbed metabolism that cause oxidative damage to biomolecules.

Functional and Pathological Roles of AHCY

open access: yesFrontiers in Cell and Developmental Biology, 2021
Adenosylhomocysteinase (AHCY) is a unique enzyme and one of the most conserved proteins in living organisms. AHCY catalyzes the reversible break of S-adenosylhomocysteine (SAH), the by-product and a potent inhibitor of methyltransferases activity.

S-adenosylhomocysteine metabolism in Streptomyces flocculus [PDF]

open access: yesJournal of Bacteriology, 1988
S-Adenosylhomocysteine metabolism was studied in cell extracts of streptonigrin-producing Streptomyces flocculus. The major route of metabolism was found to be deamination to form S-inosylhomocysteine. The metabolite was purified by high-performance liquid chromatography and identified by its UV and nuclear magnetic resonance spectra and by its ...

Transsulfuration pathway thiols and methylated arginines: the hunter community study [PDF]

open access: yes, 2013
Background: Serum homocysteine, when studied singly, has been reported to be positively associated both with the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine [ADMA, via inhibition of dimethylarginine dimethylaminohydrolase ...

DETERMINATION OF S-ADENOSYLHOMOCYSTEINE IN TISSUES FOLLOWING PHARMACOLOGICAL INHIBITION OF S-ADENOSYLHOMOCYSTEINE CATABOLISM: 84 [PDF]

open access: yesPediatric Research, 1985
The amount of S-adenosylhomocysteine in liver increases 2 to 3 fold during the first minute following death of the animal (Hoffman, D.R. et al. (1979) Can. J. Biochem. 57, 56-65), and postmortem increase in AdoHcy should be avoided when determining the physiological level of AdoHcy.

S-adenosylmethionine and superoxide dismutase 1 synergistically counteract Alzheimer's disease features progression in tgCRND8 mice [PDF]

open access: yes, 2017
Recent evidence emphasizes the role of dysregulated one-carbon metabolism in Alzheimer's Disease (AD). Exploiting a nutritional B-vitamin deficiency paradigm, we have previously shown that PSEN1 and BACE1 activity is modulated by one-carbon metabolism ...
