alcohol dehydrogenase/neoplasms

OBJECTIVE Ethanol consumption is associated with an increased risk of esophageal cancer. The carcinogenic compound is acetaldehyde, the product of ethanol metabolism. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are the main enzymes involved in ethanol metabolism, which leads to

Although there is clear evidence that smoking is the primary risk factor for lung cancer, not all variation in disease risk is understood. There is some evidence that alcohol may contribute to risk. We examined lifetime and recent (12-24 mo previous) alcohol consumption in relation to risk of lung

OBJECTIVE Because alcohol dehydrogenase 3 (ADH3) is rate-limiting in alcohol oxidation and is polymorphic, we examined ADH3 genotype in relation to alcohol intake and breast cancer risk. METHODS We conducted a case-control study among Caucasian women aged 40-85 with incident, pathologically

Epidemiological studies have demonstrated the association between alcohol consumption and the development of liver cancer. The metabolism of ethanol via alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) leads to generation of carcinogenic acetaldehyde. OBJECTIVE Comparison of the ADH

OBJECTIVE To evaluate the impact of alcohol dehydrogenase-2 (ADH2) and aldehyde dehydrogenase-2 (ALDH2) polymorphisms on the susceptibility of esophageal cancer. METHODS A case-control study including 221 cases of esophageal cancer and 191 controls was carried out in Taixing city of Jiangsu

OBJECTIVE To investigate the relationship among alcohol dehydrogenase-2 (ADH2) and aldehyde dehydrogenase-2 (ALDH2) genetic polymorphisms, alcohol consumption, and the susceptibility of stomach cancer in Chinese males. METHODS Three hundred and eighty-two stomach cancer patients and 382 healthy

We investigated effects on oral cancer (OC) risk of an interaction between a single nucleotide polymorphism (SNP) in the alcohol dehydrogenase 3 (ADH3) gene and alcohol consumption levels using a hospital-based study of 93 cases and 99 controls conducted in Athens, Greece. This SNP affects ethanol

Within the Netherlands Cohort Study (1986), we examined associations between alcohol consumption, the alcohol dehydrogenase 1C (ADH1C) genotype, and risk of colorectal cancer (CRC). After a follow-up period of 7.3 years, 594 CRC cases with information on genotype and baseline alcohol intake were

BACKGROUND It is believed that acetaldehyde plays an important role in alcohol-related carcinogenesis; although current epidemiologic studies have provided inconsistent findings on the association between alcohol consumption and the risk of lung cancer. METHODS To clarify the hypothesis that genetic

Detoxification of ethanol can contribute to oxidative cellular and DNA damage and, thereby, to carcinogenesis. The potential relevance of this to breast carcinogenesis is suggested by evidence that alcohol consumption is a risk factor for breast cancer. It is, however, not known whether ethanol can

BACKGROUND Chronic alcohol consumption is a risk factor for colorectal cancer. Animal experiments as well as genetic linkage studies in Japanese individuals with inactive acetaldehyde dehydrogenase leading to elevated acetaldehyde concentrations following ethanol ingestion support the hypothesis

Squamous cell carcinoma of the head and neck (SCCHN), including the oral cavity, pharynx and larynx, is an excellent tumor model to evaluate gene-environment interactions, including alcohol and alcohol-metabolizing enzymes such as alcohol dehydrogenase (ADH). We conducted a hospital-based

OBJECTIVE To assess alcohol dehydrogenase 3 (ADH3) polymorphism at position Ile349Val as indicator of risk factor for upper aerodigestive tract (UADT) cancer to verify its association with UADT cancer in nonalcoholic or nonsmoking individuals. METHODS Cross-sectional study. METHODS Primary care or

Alcohol is a recognized risk factor for upper aerodigestive tract (UAT) cancers, but the mechanism by which alcohol causes cancer remains obscure. Ethanol is oxidized to acetaldehyde (the suspected carcinogenic agent in alcohol) by alcohol dehydrogenases (ADHs) and cytochrome P-4502E1 (CYP2E1), both

Alcohol dehydrogenase and aldehyde dehydrogenase are key enzymes in alcohol metabolism and therefore may be of importance to colorectal cancer development. The present case-control study was conducted to determine the influence of ADH2, ADH3 and ALDH2 polymorphisms in Fukuoka, Japan, with 685
