Example sentences for: methylenetetrahydrofolate

How can you use “methylenetetrahydrofolate” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The canonical thymidylate synthase (TS), such as the E. coli ThyA, is a protein with a distinct α/β-fold that transfers a methyl group to dUMP from 5,10-methylenetetrahydrofolate [ 29].

  • The molecular basis of inherited thrombophilia now includes mutations in the genes for Factor V, prothrombin, methylenetetrahydrofolate reductase (MTHFR) and several others [ 15 ] , in addition to those encoding proteins such as antithrombin, protein C, and protein S whose role in the homeostasis between procoagulant and anticoagulant activities in the circulation is well established.

  • The most important of these are the aldose reductase gene ( ALR2 ) [ 17], the insertion/deletion (I/D) polymorphism of the angiotensin I - converting enzyme ( ACE ) gene [ 18, 19], C825T polymorphism of the gene encoding the beta-3 subunit of geterotrimeric G-proteins ( GNB3 ) [ 20, 21, 22], and C677T polymorphism of the methylenetetrahydrofolate reductase gene ( MTHFR ) [ 23].

  • However, despite association of the factor V G1691A (factor V Leiden) and prothrombin (factor II) G20210A mutations with venous thromboembolism and myocardial infarction [ 10 11 ] , neither mutation is strongly associated with risk of stroke [ 12 13 14 15 16 17 18 ] . Although a study of British adults found elevated levels of serum homocysteine to be associated with an increased risk of stroke [ 19 ] , a case-control study of a common polymorphism (methylenetetrahydrofolate reductase [MTHFR] T677C) that results in increased serum homocysteine concentrations found no difference between patients with stroke and controls in either genotype or allele frequency [ 20 ] . Because antiplatelet agents with different mechanisms of action can bring about significant reductions in stroke risk, several platelet receptor genes have been tested as candidate stroke susceptibility genes [ 21 22 ] . To date, however, no compelling evidence for an association between any platelet receptor gene polymorphism and risk of stroke has been found.

  • The breakdown of SAH, which is reversible, results in the release of free homocysteine which is converted to methionine while being used as a substrate for the reduction of 5-methylenetetrahydrofolate (5-MTHF) to tetrahydrofolate (THF).
