Head and neck cancer; Meta-analysis; Polymorphism; XPD

Several studies have investigated the association between Lys751Gln polymorphism in the xeroderma pigmentosum group D (XPD) gene and risk of head and neck cancer; however, the published results are conflicting. We conducted a meta-analysis that comprised 15 published case-control studies examining the association of head and neck cancer risk with XPD Lys751Gln ... more

Malaysia; Polymorphism; RANTES; SDF; SLE

Regulated on activation, normal T-cell expressed and secreted (RANTES) and stromal cell-derived factor 1 (SDF-1) are members of the CC- and CXC-chemokine families, respectively. Both genes have been postulated to be involved in the pathogenesis of systemic lupus erythematosus (SLE). We analyzed position 28 of the RANTES gene promoter region, as well as the SNP observed in the 3' ... more

AGPAT6 gene; Dairy goat; Milk traits; PCR-RFLP; Polymorphism

As one of the eight members in the 1-acylglycerol-3-phosphate-O-acyltransferase (AGPATs) family, AGPAT6 is a crucial enzyme for the biosynthesis of glycerolipids and triacylglycerol in eukaryotes, as well as catalyzing the conversion from lysophosphatidic acid to phosphatidic acid. AGPAT6 can be considered as a candidate gene for regulating milk composition. DNA ... more

GSTP1; Kashmir; Polymorphism; Prostate cancer; Restriction digestion; RFLP

Glutathione-S-transferase P1 (GSTP1) is a critical enzyme of the phase II detoxification pathway. One of the common functional polymorphisms of GSTP1 is A→G at nucleotide 313, which results in an amino acid substitution (Ile105Val) at the substrate binding site of GSTP1 and reduces catalytic activity of GSTP1. To investigate the GSTP1 Ile105Val genotype ... more

Human leukocyte antigen; Meta-analysis; Polymorphism; Psoriasis; Risk

Numerous studies have evaluated the association between human leukocyte antigen (HLA) Cw*0602 polymorphism and psoriasis risk. However, the results have been inconsistent. We made a meta-analysis of the association between HLA-Cw*0602 polymorphism and psoriasis risk. Eighteen studies were retrieved, reporting a total of 3419 psoriasis patients and 3297 healthy controls. The associations ... more

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
