Abstract
PDF - OBJECTIVES
To investigate effects of genetic polymorphism of glutathione S-transferase M1 (GSTM1), glutathione S-transferase T1 (GSTT1), glutathione S-transferase P1 (GSTP1), N-acetyltransferase (NAT2), cytochrome P450 2E1 (CYP2E1) and cytochrome P450 1A1 (CYP1A1) on pneumoconiosis.
METHODS
Eighty-five pneumoconiosis patients and 122 age and sex matched healthy controls were enrolled. Direct interview and standard questionnaire were conducted and the genotypes of GSTM1, GSTT1, GSTP1, NAT2, CYP2E1 and CYP1A1 were investigated using multiplex PCR or PCR-RFLP methods with DNA extracted from venous blood. The relationship was investigated between the severity of pneumoconiosis and the polymorphism of GSTM1, GSTT1, GSTP1, NAT2, CYP2E1 and CYP1A1, and also with various environmental factors including smoking.
RESULTS
We observed a significantly higher rate of genetic polymorphism in pneumoconiosis patients than in normal subjects. The odds ratio (95% CI) of NAT2 was 2.09 (1.19-3.68). In addition, smoking was related significantly with pneumoconiosis (OR 2.89, 95% CI 1.40-5.95). In multiple logistic regression analyses, NAT2 and smoking were significant risk factors for the development of pneumoconiosis (OR 1.84, 95% CI 1.00-3.37; OR 2.98, 95% CI 1.40-6.35, respectively). The age of onset of the disease and smoking were significantly related with moderate or severe pneumoconiosis (OR 0.91, 95% CI 0.83-0.99; OR 6.94, 95% CI 1.54-31.30, respectively). However there was no significant difference between the rate of genetic polymorphism of GSTM1, GSTT1, GSTP1, CYP2E1 and CYP1A1 in the two groups.
CONCLUSION
NAT2 genetic polymorphism was higher in pneumoconiosis patients than in normal subjects. The age of onset of the disease and smoking were significantly related with pneumoconiosis. However, the genetic polymorphism of GSTM1, GSTT1, GSTP1, CYP2E1 and CYP1A1 was not related with development or severity of pneumoconiosis.

Abstract

- OBJECTIVES
This study was performed to describe the distribution patterns of urinary 1-hydroxypyrene (1-OHP) and 2naphthol concentration in coke oven workers and workers not occupationally exposed to polycyclic aromatic hydrocarbons (PAH), and to determine the effects of occupation life style, and genetic polymorphism of cytochrome P450 1A1 (CYP1A1), glutathione Stransferase mu 1 (GSTM1) and theta 1 (GSTT1) on urinary 1- OHP and 2-naphthol concentration.
METHODS
The study subjects were 19 coke oven workers and 156 shipyard workers. A questionnaire was used to obtain data about detailed smoking and food intake history. Urinary 1OHP and 2naphthol concentration and genetic polymorphism of CYPIA1, GSTM1, and GSTT1 were analyzed.
RESULTS
The urinary 1-OHP and 2-naphthol concentration was higher in the coke oven workers and in smokers. Urinary 1-OHP concentration was significantly correlated with time after last intake of roasted meat in non-smoking coke oven workers, whereas urinary 2-naphthol concentration was with amount of cigarette smoking at the sampling day in smoking shipyard workers. Urinary 1-OHP, but not 2-naphthol, concentration of the shipyard workers with Ile/Ile type of CYP1A1 vas significantly lower than that of the shipyard workers with other CYP1A1 genotype.
CONCLUSIONS
Urinary 1-OHP would be a better marker for occupational exposure to PAH in coke oven workers, and urinary 2naphthol might be better for non-occupational inhalation exposure to PAH. CYP1A1 would not play an important role in the metabolism of naphthalene but in the metabolism of pyrene. -
