The vitamin subsequently isolated26 and synthesized was found to be 2 methyl-3 hydroxy-4, 5 hydroxy methyl pyridine and called pyridoxine.7 By means of an elegant series of exp...
OBJECTIVE we conducted a case-control study to investigate the association between dietary folate, vitamin B6 and vitamin B12 intake, MTHFR and MTR genotype, and breast cancer risk. METHODS Genotyping for MTHFR C677T and A1298C and MTR A2756G polymorphisms were performed using polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) method. The intake of folate, ...
