Interleukin-10; Lumbar disc degeneration; Polymorphisms; susceptibility

We investigated a possible association between interleukin (IL)-10 single nucleotide polymorphisms (SNPs) and susceptibility to and severity of lumbar disc degeneration (LDD) in a Chinese cohort of 320 patients with LDD and 269 gender- and age-matched controls. The degree of disc degeneration was determined by magnetic resonance imaging using Schneiderman’s classification. Genetic ... more

Folate; Glioma; MGMT; MTHFR; Polymorphisms

Hypomethylation of the O6-methylguanine-DNA-methyltransferase (MGMT) promoter in glioma cells has been associated with temozolomide resistance. S-adenosylmethionine (SAM), which is produced during folate metabolism, is the main source of methyl groups during DNA methylation. As a key enzyme during folate metabolism, polymorphisms of 5,10-methylenetetrahydrofolate reductase (MTHFR) may ... more

Chinese Hui population; eNOS gene; Essential hypertension; Polymorphisms

We investigated a possible association of polymorphism of the eNOS gene and essential hypertension in the Chinese Hui population; polymorphisms of rs2070744 (T>C), rs1799983 (G>T), rs1800780 (A>G), and rs3918181 (A>G) loci of the eNOS gene were examined. We found that the genotypic frequencies at rs1799983 and rs1800780 loci differed significantly between patients with ... more

Bos indicus; Insulin-like growth factor; Polymorphisms; Yearling weight

Meat quality is an important trait for the beef industry. Backfat thickness, ribeye area, and shear force are traits measured late in life, and the investigation of molecular markers associated with these traits can help breeding programs. In cattle, some polymorphisms have been related to production traits. Thus, the purpose of this study was to assess the presence of polymorphisms in ... more

Glioma risk; MDM2; Meta-analysis; p53; Polymorphisms

Epidemiological studies of the association of variants p53 Arg72Pro and MDM2 single-nucleotide polymorphism 309 (SNP309) with glioma risk have produced inconsistent results. The aim of the current study was to evaluate the association of these 2 variants with glioma susceptibility using a meta-analysis approach. For p53 Arg72Pro, 10 case-control studies including ... more

Arg904Gln; Essential hypertension; Meta-analysis; Polymorphisms; TSC

Although there have been several studies investigating a possible association between essential hypertension and TSC gene Arg904Gln polymorphisms, the results have been inconsistent. We conducted a meta-analysis of four case-control studies (one study in Europe and three studies in Asia), including 1811 essential hypertension cases and 1381 controls. The pooled results showed no ... more

Han population genetics; HLA; Polymorphisms; STR

A large number of microsatellite genetic markers have been identified in the human leukocyte antigen (HLA) region. We investigated genetic polymorphism of the nine short tandem repeat (STR) loci (D6S276, MOGCA, D6S265, MIB, D6S273, G51152, TAP1CA, RING3CA, and D6S291) in the HLA region in the Shaanxi Han population. Using a fluorescence-labeled multiplex-PCR STR typing method, 6-13 ... more

Cervical spondylotic myelopathy; Collagen IX; Polymorphisms; Smoking

We investigated a possible association of collagen IX tryptophan (Trp) alleles (Trp2 and Trp3) and smoking with cervical spondylotic myelopathy (CSM) in 172 Chinese patients and 176 age- and gender-matched controls. The smoking status was evaluated by smoking index (SI). The CSM cases had a significantly higher prevalence of Trp2 alleles (Trp2+) than controls (19.8 vs 6.2%, P = 0 ... more

Folate intake; Gastric cancer; Methylenetetrahydrofolate reductase; Polymorphisms

Folic acid and methylenetetrahydrofolate reductase (MTHFR) may both affect the development of human cancer. We conducted a population-based case-control study in a Chinese population to investigate the potential role of folate intake and MTHFR gene polymorphisms in gastric cancer, and their interaction with infection by Helicobacter pylori and tumor location. A total of ... more

Glutamate receptor; Heroin addiction; Ionotropic; N-methyl D-aspartate 2A; Polymorphisms

Heroin dependence is a debilitating psychiatric disorder with a complex inheritance mechanism. Genetic polymorphisms in functional regions of the glutamate receptor, N-methyl D-aspartate 2A (GRIN2A) gene, which encodes the 2A subunit of the N-methyl D-aspartate (NMDA) receptor, may modulate the risk of heroin addiction. We investigated the potential association between 8 single ... more
