The methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism was studied in 174 German patients with cervical artery dissection (CAD). The results were compared with published data on 927 healthy German controls. In the series of patients, the frequency of T alleles and of TT carriers was slightly higher (13.8%) than among the healthy controls (10.6%). In patients with multiple dissectio...
INTRODUCTION Important role is attributed to genetic polymorphisms influencing enzymatic activity in folate metabolism. These inherited genetic variants may influence fetal growth and fetal hypotrophy development. The aim of the study was to investigate the connection of 401A>G polymorphism of methyleneterahydrofolate dehydrogenase gene (MTHFD1) with increased risk of fetal hypotrophy. MATERI...
Women who take folic acid in the periconceptional period greatly reduce their chances of having a child with a neural tube defect (NTD). Using multivitamins may also reduce the risk of having a child with an omphalocele. In this study, we tested single nucleotide polymorphisms in folate-related enzyme genes for association with omphalocele. Polymorphisms in methylenetetrahydrofolate reductase (...
Earlier studies on the respiratory systems in symbiotic nitrogen fixation (Wilson, 1938) indicated that the root nodule bacteria (Rhizobium spp.) reduce methylene blue anerobically in the presence of many organic compounds. With few exceptions, the efficiency of a given substrate as a hydrogen donator was approximately the same whether molecular oxygen or methylene blue was used as the hydrogen...
The role of domains in defining the equilibrium and kinetic folding properties of dihydrofolate reductase (DHFR) from Escherichia coli was probed by examining the thermodynamic and kinetic properties of a set of variants in which the chain connectivity in the discontinuous loop domain (DLD) and the adenosine-binding domain (ABD) was altered by permutation. To test the concept that chain cleavag...
Amide and ureide biogenic enzymes were measured in the plant fraction of soybean (Glycine max) nodules during the period 11 to 23 days after inoculation with Rhizobium japonicum (USDA 3I1b142). Enzymes involved in the initial assimilation of ammonia, i.e. glutamine synthetase, glutamate synthase, and aspartate aminotransferase, showed substantial increases in their specific activities over the ...
Folate is an essential B vitamin required for de novo purine and thymidylate synthesis, and for the remethylation of homocysteine to form methionine. Folate deficiency has been associated with placenta-related pregnancy complications, as have SNP in genes of the folate-dependent enzymes, methionine synthase (MTR) and methylenetetrahydrofolate dehydrogenase 1 (MTHFD1). We aimed to determine the ...
