Lymph node metastases and tumor characteristics predict breast cancer prognosis but correlate imperfectly with likelihood of metastatic relapse. Discovery of genetic polymorphisms affecting metastasis may improve identification of patients requiring aggressive adjuvant therapy to prevent recurrence. We investigated associations between several variants in the BRMS1 and SIPA1 metastasis-modifyin...

In the February 15, 2009 issue of Cancer Research , Wright and colleagues (1) investigated whether polymorphisms in two vitamin E transport genes are associated with elevated prostate cancer risk resulting from altered plasma vitamin E concentrations. However, the circulating vitamin E level is influenced by many genes (2), and thus the observed associations may not necessarily reflect the func...

results the prevalence’s of aa, ac and cc genotypes were 55.2%, 24.1% and 20.7% in cad patients and 51.6%, 40.9% and 7.5% in the control subjects, respectively. the frequencies of the c allele were significantly higher in cad patients compared with control groups (p < 0.05). logistic regression analysis revealed a significant association between the c allele and the risk of cad (or = 1.61, 95%c...

Glutathione S-transferases (GSTs; EC: 2.5.1.18) are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. Functional genetic polymorphisms in genes encoding GSTM1 (a member of GST class mu; OMIM: 138350), and GSTT1 (a member of GST class theta; OMIM: 600436) have been well defined. The functional null alleles of GSTM1 and GSTT1 represent deletions of GSTM1 and GS...

Endothelial nitric oxide synthase (eNOS) is localized in caveole and has important effects on caveolar coordination through its interaction with caveolin-1 (Cav-1), which supports normal functioning of vascular endothelial cells. However, the relationship between genotypic polymorphisms of e-NOS and Cav-1 genes and ischemic stroke (IS) remains lesser reported. This hospital-based case-control s...

OBJECTIVES Polymorphisms in human papillomavirus (HPV) type 16 have been shown to be related to geographic areas and are broadly classified as European (E), African (Af), Asian (As), or Asian-American (AA). Certain variants have been reported as being more likely to cause cervical disease; our objectives were to identify new HPV16 polymorphisms, to determine the linkage of the E2 and E6/E7 regi...

Intercellular adhesion molecule-1 (ICAM-1) is expressed on vascular endothelial cells and its expression increases during the inflammatory response in patients with active Behcet's disease (BD). The ICAM1 gene mutations are associated with BD in Caucasians, but clinical features of the mutation phenotype are unknown. We analyzed ICAM1 polymorphisms in Korean BD patients to determine if there wa...

Tocopherols are a class of four natural compounds that can provide nutrition and function as antioxidant in both plants and animals. Maize kernels have low α-tocopherol content, the compound with the highest vitamin E activity, thus, raising the risk of vitamin E deficiency in human populations relying on maize as their primary vitamin E source. In this study, two insertion/deletions (InDels) w...

The status of genetic diversity, adaptation to climate change or the identification genes associated with traits interest in livestock populations has been a major concern for scientists last decades. Biotechnology evolved continuously, offering new tools and methodologies analyse genomes species. Biochemical markers protein polymorphisms were used population studies many years ago, but over th...

BACKGROUND This study aimed to investigate the association of both intercellular adhesion molecule-1 (ICAM-1) and endothelial cell adhesion molecule (E-selectin) polymorphisms using PCR technique and their role in the pathogenesis of atherosclerosis. MATERIAL/METHODS The study enrolled 285 individuals, classified into 4 groups: 63 cerebrovascular atherosclerotic patients, 75 cardiovascular pa...
