Prospective study of serum cysteine and cysteinylglycine and cancer of the head and neck, esophagus, and stomach in a cohort of male smokers

Background:The nonessential amino acid cysteine is known to be involved in many antioxidant and anticarcinogenic pathways. Cysteinylglycine is a pro-oxidant metabolite of glutathione and a precursor of cysteine.

Multiple Myeloma Mortality in Relation to Obesity Among African Americans

Multiple myeloma (MM) incidence and mortality are higher among African Americans (AAs) than among other population groups. The prevalence of obesity is also elevated among AAs, but few studies have examined risk of this cancer in relation to body size among AAs. We combined data from seven prospective cohorts tracking mortality among 239 597 AA adults and used Cox proportional...

Folate intake, post–folic acid grain fortification, and pancreatic cancer risk in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial

Background: Folate plays a critical role in DNA methylation, synthesis, and repair. Several epidemiologic studies suggest that higher folate intake is associated with decreased pancreatic cancer risk.

Association of dietary protein intake and coffee consumption with serum homocysteine concentrations in an older population

Background: Elevated blood concentrations of total homocysteine (tHcy) have been implicated in the pathogenesis of atherosclerotic cardiovascular disease. Previous studies identified suboptimal nutritional status and dietary intake of folate, vitamin B-6, and vitamin B-12 as determinants of elevated tHcy.

Folate Intake and Risk of Pancreatic Cancer: Pooled Analysis of Prospective Cohort Studies

Epidemiological studies evaluating the association between folate intake and risk of pancreatic cancer have produced inconsistent results. The statistical power to examine this association has been limited in previous studies partly because of small sample size and limited range of folate intake in some studies.

Pancreatic Cancer Risk and Nutrition-Related Methyl-Group Availability Indicators in Male Smokers

BACKGROUND: Few risk factors for pancreatic cancer have been identified, with age and cigarette smoking being the most consistent. The protective effect associated with consumption of fruits and vegetables—the major dietary sources of folate—is suggestive of a role for factors influencing cellular methylation reactions; however, to our knowledge, no study has investigated this...
