PURPOSE The effects of estrogens are mediated primarily through estrogen receptor (ER) in breast tissue, and polymorphisms in the ER genes may alter the functions of these receptors. Polymorphisms in the ER-alpha gene have been reported to be associated with breast cancer risk. However, to our knowledge, no study has been published on the relation between ER-alpha gene polymorphisms and breast ...

The CYP3A subfamily enzymes are the most abundant and important drug-metabolizing enzymes. Wide variation in the CYP3A5 expression was well known. Recently, G(-44) to A of CYP3AP1 was found to segregate with CYP3A5*3 defective allele. The homozygous A(-44) subjects showed low expression of CYP3A5. In Caucasian, only 9.2% of CYP3AP1 alleles were with G(-44) and associated with the wild-type CYP3...

BACKGROUND Hypercoagulability and a tendency for thromboembolic complications are reported in Cushing's syndrome (CS). The hypercoagulability is due mainly to the cortisol-induced increase in von Willebrand factor (VWF) and factor VIII. This is not a constant feature of CS, however; it depends on particular single nucleotide polymorphism (SNP) haplotypes in the VWF gene promoter: haplotype 1 (-...

A length polymorphism of GT repeats in the promoter region of the human heme oxygenase-1 (HO-1) gene modulates its gene transcription to protect against myocardial injury. The present study investigated the association between HO-1 promoter polymorphisms and the outcomes of catheter ablation of atrial fibrillation (AF). The allelic frequencies of GT repeats in the HO-1 gene promoter were screen...

BACKGROUND Numerous interactions between the coagulation and complement systems have been shown. Recently, links between coagulation and mannan-binding lectin-associated serine protease-1 (MASP-1) of the complement lectin pathway have been proposed. Our aim was to investigate MASP-1 activation of factor XIII (FXIII), fibrinogen, prothrombin, and thrombin-activatable fibrinolysis inhibitor (TAFI...

Background Toll-like receptor 2 (TLR2) is critical in bringing up immune responses to mycobacterial infections. The mutations in TLR2 are known to confer susceptibility for severe infection with mycobacteria. TLR2 may diminish response to mycobacterial proteins and place individuals at risk of developing leprosy. We investigated the association of GT repeat polymorphism in intron2 of TLR2 gene ...

F13A1 gene, which encodes for Factor XIII-A blood clotting factor and a transglutaminase enzyme, was recently identified as a potential causative gene for obesity in humans. In our previous in vitro work, we showed that FXIII-A regulates preadipocyte differentiation and modulates insulin signaling via promoting plasma fibronectin assembly into the extracellular matrix. To understand the role of...

BACKGROUND Postoperative haemorrhage in neurosurgery is associated with significant morbidity and mortality. There is controversy whether or not factor XIII (FXIII) deficiency leads to bleeding complications after craniotomy. Decreased fibrinogen levels have been associated with an increased incidence of bleeding complications in cardiac and orthopaedic surgery. The aim of this study was to ass...

OBJECTIVE Factor XIII (FXIII), a plasma transglutaminase that stabilizes fibrin clots at the final stages of blood coagulation by crosslinking fibrin monomers, is essential for embryo implantation and participates in tissue remodeling and wound healing, processes that involve angiogenesis. The aim of our study was to analyze the effect of FXIII on angiogenesis using in vitro and in vivo models ...

Recently, some studies concerning let-7 binding site polymorphism in KRAS 3’-untranslated region (3’UTR) found that rs712 G/T polymorphism increased cancer risk in Chinese population. However, in consistent or contradictory results occurred. Therefore, we performed a comprehensive meta-analysis to clarify this association. Available data from PUBMED, EMBASE, and Chinese National Knowledge In fr...
