Idiopathic recurrent pregnancy loss (IRPL) is defined by three or more consecutive miscarriages occurring before the twentieth week of gestation as a result of unidentified etiological factors. The results of previous studies have indicated that prothrombotic factors play a pathogenic role in early and late pregnancy. This study aimed to identify inherited prothrombotic and ... more

High plasma homocysteine (Hcy) ​​levels may be responsible for vaso-occlusive episodes and may have acquired and/or genetic causes. This cross-sectional study aimed to investigate the role of methylenetetrahydrofolate reductase (MTHFR; C677T; A1298C) and cystathionine-β-synthase (CBS; T833C/844ins68, G919A) polymorphisms in serum levels of folic acid, vitamin B12 and Hcy, and to verify a ... more

Coronary artery disease; IL-17A; IL-17F; Polymorphism

A case-control study was conducted to investigate the association between genetic variants of IL-17A rs2275913 and IL-17F rs763780 and the development of coronary artery disease (CAD) in a Chinese population. A total of 306 individuals with CAD and 306 unaffected individuals were enrolled from the Zhengzhou People’s Hospital between May 2012 and May 2014. The IL-17A ... more

DNA repair genes; Osteosarcoma; Overall survival; Polymorphism

We conducted a perspective study to investigate the role of ERCC1 (rs11615), ERCC2 (rs13181 and rs1799793), ERCC4 (rs1800067), and ERCC5 (rs17655) in NER pathway in the prognosis of osteosarcoma patients. In total, 146 osteosarcoma patients were recruited between 2008 and 2013. ERCC1 rs11615, ERCC2 rs13181 and rs1799793, ERCC4 rs1800067, and ERCC5 rs17655 gene polymorphisms were assessed ... more

Chemotherapy; Clinical outcome; Glutathione S-transferases; Polymorphism

The aim of this study was to evaluate the role of GSTM1 null/present, GSTT1 null/present, and GSTP1 IIe105Val polymor­phisms in the clinical response to chemotherapy and treatment outcome of patients with breast cancer. A total of 262 subjects were randomly selected from among patients with a histologically confirmed breast cancer. The genotypes of GSTM1, ... more

We conducted this case-control study to assess the role of the VEGF -2578C/A, +1612G/A, +936C/T and -634G/C gene polymorphisms in the development of renal cell carcinoma (RCC). A hospital-based case-control study was conducted in a 360 consecutive primary RCC patients and 360 age and gender-matched controls during January 2010 and January 2014. The polymerase chain reaction-restriction ... more

broiler; Candidate gene; Polymorphism; Production trait; QTL

Genetic selection for production traits has resulted in a rapid improvement in animal performance and development. Previous studies have mapped quantitative trait loci for body weight at 35 and 41 days, and drum and thigh yield, onto chicken chromosome 4. We investigated this region for single nucleotide polymorphisms and their associations with important economic traits. Three positional ... more

Clinical outcome; ERCC1; ERCC2; Osteosarcoma; Polymorphism

We aimed to evaluate the influence of four SNPs in ERCC1 and ERCC2 on the response to cisplatin-based treatment and on clinical outcome in patients with osteosarcoma. We identified 186 patients with osteosarcoma diagnosed between April 2009 and April 2011 who were eligible for inclusion in our study. Genotyping of ERCC1 rs11615, rs3212986, and rs2298881; and ... more
