Novel associations of UDP-glucuronosyltransferase 2B gene variants with prostate cancer risk in a multiethnic study.

BACKGROUND: We have previously shown that a functional polymorphism of the UGT2B15 gene (rs1902023) was associated with increased risk of prostate cancer (PC). Novel functional polymorphisms of the UGT2B17 and UGT2B15 genes have been recently characterized by in vitro assays but have not been evaluated in epidemiologic studies. METHODS: Fifteen functional SNPs of the UGT2B17 and UGT2B15 genes, including cis-acting UGT2B gene SNPs, were genotyped in African American and Caucasian men (233 PC cases and 342 controls). Regression models were used to analyze the association between SNPs and PC risk. RESULTS: After adjusting for race, age and BMI, we found that six UGT2B15 SNPs (rs4148269, rs3100, rs9994887, rs13112099, rs7686914 and rs7696472) were associated with an increased risk of PC in log-additive models (p < 0.05). A SNP cis-acting on UGT2B17 and UGT2B15 expression (rs17147338) was also associated with increased risk of prostate cancer (OR = 1.65, 95% CI = 1.00-2.70); while a stronger association among men with high Gleason sum was observed for SNPs rs4148269 and rs3100. CONCLUSIONS: Although small sample size limits inference, we report novel associations between UGT2B15 and UGT2B17 variants and PC risk. These associations with PC risk in men with high Gleason sum, more frequently found in African American men, support the relevance of genetic differences in the androgen metabolism pathway, which could explain, in part, the high incidence of PC among African American men. Larger studies are required.

Politics and Poetics of the Novel: Using Domesticity to Create the Nation

This thesis examines how the depiction of the family during war reinforces or challenges societal values in three nineteenth-century novels. The primary focus lies in three novels by Sir Walter Scott, Leo Tolstoy, and Harriet Beecher Stowe that represent the perspectives of England, Russia, and the United States, respectively, and their evolving nationalism as the roots of the Napoleonic Wars and the American Civil War became visible. By investigating the interaction between economic classes, it can be concluded that the preservation of the family is inherently dependent on social status in some nations, while in others, it is integral to daily life regardless of class. The backdrop of impending war only serves to heighten national differences, overturn the organization of the family hierarchy, and redefine the idea of the modern household.
