Lung cancer risk; Meta-analysis; p21; Polymorphism; Ser31Arg

The cyclin-dependent kinase inhibitor 1A (also known as p21) is thought to be involved in tumor development by mediating cell cycle arrest through the inhibition of cyclin/CDK activity. To explore the relationship of Ser31Arg polymorphism in the p21 gene with the risk of developing lung cancer, we performed an overall and stratified meta-analysis based on ethnicity, lung ... more

Association analysis; Candidate gene; Chicken; Egg number at 300 days of age; Polymorphism; QTL

We looked for variations that could be associated with chicken egg number at 300 days of age (EN300) in seven genes of the hypothalamic-pituitary-gonadal axis, including gonadotrophin-releasing hormone-I (GnRH-I), GnRH receptor (GnRHR), neuropeptide Y (NPY), dopamine D2 receptor (DRD2), vasoactive intestinal polypeptide (VIP), VIP receptor-1 ( ... more

Genetic marker; Larus saundersi; Microsatellite; Polymorphism; Saunders’s gull

Nine polymorphic microsatellite loci were isolated, using tetranucleotide repeat oligonucleotide probes from an enriched DNA library of the globally “vulnerable” Saunders’s gull (Larus saundersi), collected from the Yancheng coastal wetland, one of the three remaining breeding sites in China. Six breast muscle tissues and 16 blood samples from 22 gulls and eight eggshell membrane ... more

BMD; CYP17; CYP19; Estradiol; Osteoporosis; Polymorphism

Many clinical conditions, including osteoporosis, are associated with serum levels of sex steroids. Enzymes that regulate rate-limiting steps of steroidogenic pathways, such as CYP17 and CYP19, are also regarded as significant factors that may cause the development of these conditions. We investigated the association of two common polymorphisms, in the promoter region (T→C substitution) ... more

Aggrecan gene; Disc degeneration; Lumbar; Polymorphism

We investigated a possible association between aggrecan gene polymorphism and lumbar degenerative disc disease in Turkish patients. One hundred 20-30-year-old patients with or without low back pain were selected for the study. Lumbar magnetic resonance imaging was performed on all patients. The patient group had low back pain clinically and degenerative disc disease ... more

Invasive species; Microsatellite; Polymorphism; Pseudorasbora parva

The Asiatic topmouth gudgeon, Pseudorasbora parva, is recognized as one of the most invasive fish species in many countries outside of Asia. We isolated and characterized 19 microsatellite loci from P. parva. The polymorphism of these 19 loci was tested on 40 individuals of P. parva sampled from a wild population located in Ezhou, Hubei province of China. The ... more

Bipolar disorder; Polymorphism; RELN; Schizophrenia

Reelin is an extracellular signaling protein that plays an important role in the development of the central nervous system. Post-mortem studies have shown lower reelin protein levels in the brains of patients with schizophrenia and bipolar disorder compared with controls. Genetic studies have also shown that mutations in the reelin gene (RELN) increase the risk for schizophrenia ... more

5' Anchored PCR; Larimichthys polyactis; Microsatellite markers; Polymorphism; Redlip croaker

Larimichthys polyactis is a commercially important marine fish species in southeast Asia. The population crashed due to overfishing in the 1970s, but has since recovered. We developed 13 novel polymorphic microsatellite markers in L. polyactis using 5' anchored PCR. The characteristics of these loci were estimated by analyzing a sample of 30 individuals. A total of 74 ... more

Colorectal cancer; Kashmir; MTHFR; Polymorphism; Restriction digestion; RFLP

Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme in folate metabolism and is involved in DNA synthesis, DNA repair and DNA methylation. The two common functional polymorphisms of MTHFR, 677 C→T and 1298 A→C, have been shown to impact various diseases, including cancer. The 677 C→T polymorphism has been widely investigated in different cancers and has been ... more

Astrocytoma; Glioblastoma; Polymorphism; XRCC1

XRCC genes (X-ray cross-complementing group) were discovered mainly for their roles in protecting mammalian cells against damage caused by ionizing radiation. Studies determined that these genes are important in the genetic stability of DNA. Although the loss of some of these genes does not necessarily confer high levels of sensitivity to radiation, they have been found to represent ... more
