New insights into erythropoiesis: the roles of folate, vitamin B12, and iron.
Koury MJ, Ponka P. Koury MJ, et al. Annu Rev Nutr. 2004;24:105-31. doi: 10.1146/annurev.nutr.24.012003.132306. Annu Rev Nutr. 2004. PMID: 15189115 Review.
These new erythrocytes replace the oldest erythrocytes (normally about one percent) that are phagocytosed and destroyed each day. Folate, vitamin B12, and iron have crucial roles in erythropoiesis. Erythroblasts require folate and vitamin B12 for proli …

Vitamin B12-folate interrelationships.
Shane B, Stokstad EL. Shane B, et al. Annu Rev Nutr. 1985;5:115-41. doi: 10.1146/annurev.nu.05.070185.000555. Annu Rev Nutr. 1985. PMID: 3927946 Review.
The studies discussed in this review support the view that biochemical and clinical symptoms common to both folate and vitamin B12 deficiency are due to the induction of a functional folate deficiency, which in turn is induced by cobalamin deprivation. The in …

Folate and B12 in prostate cancer.
Collin SM. Collin SM. Adv Clin Chem. 2013;60:1-63. doi: 10.1016/b978-0-12-407681-5.00001-5. Adv Clin Chem. 2013. PMID: 23724740 Review.
However, epidemiological studies of prostate cancer risk, based on dietary intakes and blood levels of folate and vitamin B12 and on folate-pathway gene variants, have generated contradictory findings. ...Meta-analysis does not entirely rule out a positive as …

Folate and B12 serum levels in association with depression in the aged: a systematic review and meta-analysis.
Petridou ET, Kousoulis AA, Michelakos T, Papathoma P, Dessypris N, Papadopoulos FC, Stefanadis C. Petridou ET, et al. Aging Ment Health. 2016 Sep;20(9):965-73. doi: 10.1080/13607863.2015.1049115. Epub 2015 Jun 8. Aging Ment Health. 2016. PMID: 26055921 Review.
The Newcastle-Ottawa scale was used to evaluate the quality of included studies. RESULTS: Both gender data were contributed by 11 folate-related (7949 individuals) and 9 B12-related studies (6308 individuals), whereas gender-specific data by 4 folate-related …

In vitamin B12 deficiency, blocking of the methylation cycle causes the folate cofactors in the cell to become trapped as 5-methyltetrahydrofolate. This process in turn produces a pseudo folate deficiency in such cells, preventing cell division and giving ris …
