The methylenetetrahydrofolate reductase (MTHFR) gene plays an important role in the steps involved in the processing of amino acids. The analysis of polymorphisms in the MTHFR gene has revealed associations with cancer; in particular the C677T polymorphism, which has been suggested to affect folate metabolism, DNA methylation, synthesis, and repair, and t..

Pituitary adenomas can cause endocrine disorder and organ damage, with some aggressive ones leading to a high postoperative recurrence rate. The occurrence and development of these type of tumors is closely related with matrix metalloproteinases (MMPs) and endogenous specific tissue inhibitor of MMPs (TIMPs). In this study, the relationship between pituit.. Read More»

The aim of this study was to investigate the effect of a small interfering RNA (siRNA) targeting human epidermal growth factor receptor 2 (HER2/neu) on the proliferation and viability of prostate cancer PC-3M cells. Chemically synthesized siRNA targeting HER2/neu was transfected into PC-3M cells by using liposomes, and cells transfected with empty liposom.. Read More»

The Orchidaceae represent one of the largest and most diverse families on the planet. However, this family is constantly threatened by predators and by the advancement of urban centers over its natural habitats. The objective of this study was to use inter-simple sequence repeat markers to evaluate the genetic diversity betwee.. Read More»

Previous studies have shown that cytokines can affect serum lipoprotein concentrations. The aim of this study was to examine the association between IL-10 gene polymorphisms and serum lipoprotein levels of Han Chinese individuals. A total of 359 Han Chinese people were enrolled in this investigation. IL-10 -592, -819, and -108.. Read More»

Previous studies suggested that dopamine receptors may be associated with drug dependence and impulsive behavior. In this study, we examined whether dopamine receptor D1 (DRD1) is associated with heroin dependence and the impulsive behavior in patients with heroin dependence. The participants included 367 patients with heroin dependence and 372 healthy co.. Read More»

The etiology underlying neural tube defects (NTDs) is not fully understood and is believed to involve a complex milieu of genetic and environmental factors. The A1298C polymorphism in the methylenetetrahydropholate reductase gene (MTHFR) has been associated with mild risk for NTDs. In this study, the genotype distribution of t.. Read More»
