Objective: The influence of the vitamins A, C, and E on breast cancer development has not
been clarified. An effect of a vitamin per se implicates similar patterns for the effects of the …

Background An accumulating body of evidence suggests that there is an inverse
relationship between the intake of folate (a water-soluble B-vitamin) and the risk of …

Methylenetetrahydrofolate reductase (MTHFR) regulates the intracellular folates pool for
DNA synthesis and methylation. Sequence variations in MTHFR (nucleotides 677 (C→ T) …

The interconversion of folates by the one-carbon metabolism pathway is essential for the
synthesis of precursors used in DNA synthesis, repair, and methylation. Perturbations in this …

The association between diet and breast cancer risk has been investigated extensively and
has led to some recommendations for prevention. Research suggests that maintaining a …

Aberrations in one-carbon metabolism were reported to increase breast cancer risk by
influencing the DNA synthesis and methylation of DNA and catecholamines. However, the …

Background & aims Vitamin K prevents growth and metastasis of certain cancers, but there
is little evidence regarding the association between dietary vitamin K and breast cancer …

Background The association between vitamin A intake and breast cancer survival has been
inconsistent. We conducted a systemic review and meta-analysis to summarize the results …

To investigate the incidence of breast cancer and prediagnostic serum levels of folate, B12,
and pyridoxal 5′-phosphate (B6), we conducted a nested case-control study using …

Low B-vitamin intake may increase risk of breast cancer through decreased DNA repair
capacity. Alcohol intake increases risk for breast cancer, with evidence from prospective …
