We characterized 13 accessions of dry peas of different origins from various growing regions in Argentina, based on three replications of 20 plants cultivated in 2009 and 2010 in a greenhouse, with the objective of selecting those with favorable characteristics for use in breeding programs. Significant differences were found for length and width of stipule and pod, length of the ... more

The study of phylogenetic relationships between 14 Colchicum taxa spread throughout Turkey was performed using a fluorescent-based amplified fragment length polymorphism (AFLP) technique. Five primer pair combinations were used in AFLP reactions. The data set was analyzed statistically using the NTSYS 2.1 software, and the neighbor-joining and maximum parsimony methods were ... more

Polycystic ovary syndrome is one of the most frequently encountered endocrine malfunctions. Methylenetetrahydrofolate reductase (MTHFR) plays a vital role in folate metabolism, DNA methylation, and RNA synthesis. We carried out a study to investigate the association between MTHFR C677T and A1298C genetic variations and the risk of polycystic ovary syndrome in a Chinese population. We recruited ... more

Non-small cell lung cancer (NSCLC) is the most common cancer globally. The XRCC1 protein interacts with ligase and poly(ADP-ribose) polymerase to repair cisplatin-induced DNA damage. The authors of previous studies have reported XRCC1 Arg399Gln, Arg280His, and Arg194Trp polymorphisms and advanced NSCLC prognosis, but the results are inconclusive. We investigated the association between ... more

Because of their local adaptation and economic factors that limit the adoption of commercial hybrids, farmer-saved maize landraces are still grown over a considerable area concentrated in southwest China. To evaluate the potential of using maize landraces, the germplasm characteristics of 96 landraces from southwest China were evaluated at phenotypic, cellular, and molecular levels. The ... more

The aim of this study was to investigate the tumor protein p73 (TP73) G4C14-A4T14 polymorphism and to perform a meta-analysis to assess TP73 expression in cervical cancer and precancerous tissue. Articles containing data regarding TP73 status in cervical cancer patients and healthy controls were retrieved from PubMed, EMBASE, Cochrane, Chinese Biomedical Literature, and China National ... more

PPARD encodes for peroxisome proliferator-activated receptor delta, which plays a significant role in controlling lipid metabolism, atherosclerosis, inflammation, cancer growth, progression, and apoptosis. Accumulated evidence suggests that the polymorphism rs2016520 in PPARD is associated with lipid metabolism, obesity, metabolic syndrome, and type 2 diabetes mellitus. The aim of this study ... more

Glutathione S-transferase (GST) is an important member of phase II metabolic enzymes; GSTM1, GSTT1, and GSTP1 belong to three subfamilies of the GST enzyme. Polymorphisms in GSTM1, GSTT1, and GSTP1 could affect detoxification processes, and increase individuals' susceptibility to cancers. We aimed to investigate the association between GSTM1, GSTT1, and GSTP1 polymorphisms and the risk of ... more

Congenital deafness is a serious and irreversible condition in humans. The GJB2 gene is implicated in the pathogenesis of autosomal recessive nonsyndromic hearing loss. Its 235delC and 30-35delG polymorphisms are reported to be associated with risk of hereditary deafness. However, the effect of the interaction between GJB2 235delC and 30-35delG and environmental factors on congenital deafness ... more
