Abstract

OBJECTIVES
Previous human trials have not supported the anticarcinogenic effect of vitamin E despite biological plausibility and considerable epidemiological evidence. A possible explanation for this inconsistency is the interactive effect of the catechol-O-methyltransferase (COMT) gene and supplemental vitamin E on cancer. We examined whether a COMT gene variant modulates the effect of dietary vitamin E intake on colorectal cancer (CRC) risk.

METHODS

In this case-control study of Korean adults (975 cases and 975 age- and sex-matched controls), dietary vitamin E density (mg/1,000 kcal) was measured using a semiquantitative food frequency questionnaire, COMT single nucleotide polymorphism (SNP) rs740603 (A>G) was genotyped, and CRC was verified histologically. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) using unconditional logistic regression models with adjustments for potential confounders.

RESULTS

Higher vitamin E density was associated with a lower risk of CRC (highest vs. lowest quartiles: OR, 0.72; 95% CI, 0.55 to 0.96; p-for-trend=0.002). When stratified by COMT SNP rs740603 genotype, the inverse association between vitamin E density and CRC risk was confined to those with at least 1 A allele (≥median vs. <median: OR, 0.63; 95% CI, 0.51 to 0.78). The interaction between rs740603 and vitamin E density was significant (p-for-interaction=0.020). No direct association was observed between COMT SNP rs740603 and CRC risk (OR, 1.08; 95% CI, 0.83 to 1.41).

CONCLUSIONS

Our findings support a role for a genetic polymorphism in COMT in modifying the association between dietary vitamin E intake and CRC.

Summary

Korean summary
본 연구는 국립암센터에서 수집한 대장암 환자-대조군 자료를 활용하여, catechol-O-methyltransferase (COMT) 유전자의 단일염기다형성(SNP)에 따라 비타민 E 섭취와 대장암 위험 간의 연관성이 달라지는지 파악하고자 하였다. 분석 결과, COMT SNP rs740603의 유전자형에 따라 식이를 통한 비타민 E 섭취 밀도와 대장암 위험 간의 연관성이 다르게 나타나 COMT 유전자와 비타민 E 섭취 간의 상호작용이 대장암 발생 위험에 영향을 미칠 가능성이 있음을 제시하였다.

Key Message
In this case-control study of Korean adults, we examined whether a polymorphism in the catechol-O-methyltransferase (COMT) gene modulates the effect of dietary vitamin E intake on colorectal cancer risk. Our results suggest that the inverse association between vitamin E density and colorectal cancer risk is confined to carriers of the COMT rs740603 A allele. The findings of our study support the interactive effect of the COMT gene and vitamin E intake on colorectal cancer risk.

Abstract

The hygiene hypothesis (HH) proposed by Strachan in 1989 was expanded to explain the inverse association between the occurrence of allergy disorders and the risk of infectious diseases and parasite infestation. The microflora hypothesis (MH) suggests that gut microbial dysbiosis in early life might trigger hypersensitivity disorders. The sharing concept of both HH and MH is gene-environment interaction, which is also a key concept in epigenetics. The amalgamation of epidemiology and epigenetics has created a scientific discipline termed epigenetic epidemiology. To accomplish an era of gene-environment-wide interaction studies, it is necessary to launch a national human epigenome project.

1989년 제시된 위생가설 (Hygiene hypothesis)은 최근 체내미생물가설 (Microflora hypothesis) 대치되어 알레르기 질환의 발생기전을 해석하고 있다. 두 가설 모두 유전-환경 상호작용 gene-environment interaction) 을 강조하고 있다는 점에서 향후 후성유전역학 연구에 대한 활성화가 필요하다.
