Polymorphisms of estrogen receptor-α gene in Brazilian women with high breast density after menopause

The association of genetic polymorphism in the estrogen receptor alpha (ERα) gene and risk for diseases including breast cancer (BC) has been the subject of great interest. Objective: Checking on women with high breast density after menopause, the frequency of the Pvull and Xbal polymorphisms of the ERα gene and the correlation between them and the known risk factors for breast cancer. Method: Observational study with 308 women between 45 and 65 years old with high breast density, without hormonal therapy, menstruation for a year or more, breast and ovarian cancer history. It was characterized in clinical history and physical examination: menarche, menopause, parity, family history of BC, smoking, alcohol intake and body mass index. Results: The allelic and genotypic frequencies for ERα-Pvull and Xbal: p=43.99%; p=56.01%; pp=32.14%; Pp=47.73% and PP=20.13%; X=41.56%; x=58.44%; xx=33.44%; Xx=50.00% and XX=16.56%, respectively. The most frequent risk factors for BC: menarche before 12 years old (35.38%), nulliparity or first child after 28 years old (41.66%), family history of BC (19.16%) and overweight/obesity (62.01%). Conclusion: Allelic and genotypic distribution similar to literature. The risk factors for BC were more prevalent in women with high breast density but without significant associations with these polymorphisms. © 2013 Informa UK Ltd. All rights reserved.

NLRP1 L155H polymorphism is a risk factor for preeclampsia development

Problem: Augmented levels of IL-1 ss have been pointed out as an important pathogenic factor for preeclampsia development. Inflammasome is the cytoplasmic complex responsible for pro-IL1 ss cleavage and IL-1 ss secretion. Aim of the study was to evaluate the association between polymorphisms in inflammasome'genes and preeclampsia. Method of study: Selected polymorphisms in inflammasome genes (NLRP1, NLRP3, CARD8, and IL1B) were analyzed in 286 Brazilian women with and 309 without preeclampsia. Results and Conlclusions: The NLRP1 variant rs12150220 (L155H) was associated with the development of preeclampsia (OR=1.58), suggesting a role of this inflammasome receptor in the pathogenesis of this multifactorial disorder.
