Blood α-Tocopherol, γ-Tocopherol Levels and Risk of Prostate Cancer: A Meta-Analysis of Prospective Studies
BACKGROUND Epidemiological studies that have examined the association of blood α-tocopherol and γ-tocopherol (the principal bioactive form of vitamin E) levels with the risk of prostate cancer have yielded inconsistent results. In addition, a quantitative assessment of published studies is not available. METHODS AND FINDINGS In this meta-analysis, relevant studies were sought by a search of t...
متن کاملSerum α-Tocopherol and γ-Tocopherol Concentrations and Prostate Cancer Risk in the PLCO Screening Trial: A Nested Case-Control Study
BACKGROUND Vitamin E compounds exhibit prostate cancer preventive properties experimentally, but serologic investigations of tocopherols, and randomized controlled trials of supplementation in particular, have been inconsistent. Many studies suggest protective effects among smokers and for aggressive prostate cancer, however. METHODS We conducted a nested case-control study of serum α-tocophe...
متن کاملAssociation Between - Tocopherol , - Tocopherol , Selenium , and Subsequent Prostate Cancer
Background: Selenium and -tocopherol, the major form of vitamin E in supplements, appear to have a protective effect against prostate cancer. However, little attention has been paid to the possible role of -tocopherol, a major component of vitamin E in the U.S. diet and the second most common tocopherol in human serum. A nested case–control study was conducted to examine the associations of -to...
متن کاملFolate intake, serum folate levels, and prostate cancer risk: a meta-analysis of prospective studies
BACKGROUND Studies have reported inconsistent results concerning the existence of associations of folate intake and serum folate levels with prostate cancer risk. This study sought to summarise the evidence regarding these relationships using a dose-response meta-analysis approach. METHODS In January 2014, we performed electronic searches of PubMed, Embase, and the Cochrane Library to identif...
متن کاملAssociations of Serum Retinol, α-Tocopherol, and γ-Tocopherol with Biomarkers among Healthy Japanese Men
Retinol, α-tocopherol, and γ-tocopherol are fat-soluble vitamins acting as antioxidants via the prevention of lipid oxidation. Little is known about circulatory levels in healthy individuals. The present cross-sectional study aimed at elucidating the relationship between these antioxidants and clinical biomarkers in 206 male (median age 41 years, range 23-67) employees from companies located in...
