Article Abstract
Objective: The incidence of lung adenocarcinoma (LAD) is increasing worldwide. Single-nucleotide polymorphisms in aldehyde dehydrogenase 2 family member gene ( ALDH2 ) rs671 and alcohol dehydrogenase 1B ( ADH1B ) rs1229984 are common and functionally important genetic variants to metabolize endogenous and exogenous aldehyde chemicals, related to cancer.
Methods: This is a case-control study. A total of 150 newly diagnosed LAD patients were from Kaohsiung Medical University Hospital, Taiwan, between 2019 and 2022. Two control groups, TWB-1 ( n = 600) and TWB-2 ( n = 29 683), were selected from Taiwan Biobank (TWB), and the case patients were frequency-matched with TWB-1 based on age category (30-60 or >60 years old), sex, and education levels. Logistic regression models were employed to analyze the association between two genetic variants and LAD risk.
Results: A significant association was noted between ALDH2 and LAD risk. Those with ALDH2 rs671 *2/*2 in TWB-1 and TWB-2 controls had a 2.68-fold (95% CI = 1.43-4.99) and a 1.83-fold (95% CI = 1.07-3.11) increased risk of LAD, respectively, compared with those with ALDH2 rs671 *1/*1 or *1/*2 , after adjusting for covariates. This association was particularly pronounced in females. No overall significant association between ADH1B rs1229984 and LAD risk was observed.
Conclusion: The findings indicate a strong and robust risk association between ALDH2 rs671*2/*2 and LAD in the Taiwan population, particularly in Taiwanese female adults.

Recent advancements in genome sequencing have enabled the estimation of genetic load through deleterious mutation profiling. However, Chinese populations remain underexplored in this context. We analyze whole-exome sequencing data from 5002 individuals, encompassing major Han subgroups-North Han (N-Han), South Han (S-Han), and Guangxi Han (G-Han)-as well as 13 ethnic minorities.

Alcohol use disorder (AUD) is a growing public health issue which has caused global concern. Previous evidence has identified several genes significantly associated with alcohol-related traits. However, it remains unclear whether these associations are robust across different ethnic groups and whether they may be moderated by some specific social factors.

Background And Aims: The association between alcohol-metabolizing enzyme polymorphisms and treatment response to nalmefene for alcohol dependence has not been studied. We aimed to determine whether alcohol-metabolizing enzyme polymorphisms, specifically ADH1B rs1229984 and ALDH2 rs671, modify the treatment response to nalmefene for alcohol dependence.
Design: Secondary analysis of a Japanese randomized clinical trial, in which participants were randomly assigned (4:3:4) to placebo, 10 mg nalmefene or 20 mg nalmefene groups for 24 weeks, accompanied by a brief psychosocial intervention.

Aims/introduction: The sex-specific association between alcohol consumption and glycemic level and whether the association differs by genetic susceptibility to alcohol is unclear. The present study aimed to examine the association of alcohol consumption and genetic variants in alcohol-metabolizing enzymes with glycemic level, as well as their sex differences, in East Asian individuals with type 2 diabetes.
Materials And Methods: In total, 4,923 Japanese individuals with type 2 diabetes were included.

Aldehyde dehydrogenase 2 (ALDH2) is a mitochondrial enzyme that detoxifies multiple aldehyde species in the body. The ALDH2∗2 allele (E487K) is one of the most common gene polymorphisms in humans, resulting in dysfunction of its enzyme activity. This study investigated in vivo mechanism of acute liver injury caused by exposure to allyl alcohol (AA) using Aldh2∗2 knock-in (KI) mice with the same amino acid replacement as human ALDH2∗2.
