Objectives: To investigate the relationship between the metabolic activation enzyme cytochrome P4501A1 gene (CYP1A1) polymorphism and lung cancer in the Chinese population. Methods: Case-control study was used to investigate the distribution frequencies of the CYP1A1 polymorphic genotypes in 98 lung cancer patients and 98 healthy subjects and analyze the relationship between gene polymorphism a...

Sex allocation theory predicts that mothers should adjust their sex-specific reproductive investment in relation to the predicted fitness returns from sons versus daughters. Sex allocation theory has proved to be successful in some invertebrate taxa but data on vertebrates often fail to show the predicted shift in sex ratio or sex-specific resource investment. This is likely to be partly explai...

OBJECTIVE Previous studies investigating the relationship between glutathione S-transferase T1 (GSTT1) gene deletion polymorphism and lung cancer risk among Chinese population produced inconsistent results. To obtain a precise conclusion, we performed this meta-analysis to evaluate the association between GSTT1 deletion polymorphism and lung cancer risk among Chinese population. METHODS The d...
