Objectives: Glutathione S-transferase (GST) polymorphism may play a role in the etiology of type 1 diabetes, as GST is involved to detoxification reactive oxygen radicals and synthesis proinflammatory mediators. Genetic polymorphisms renin-angiotensin aldosterone system, including angiotensin converting enzyme (ACE) gene insertion-deletion (I/D) polymorphism, can affect progression diabetes dia...

BACKGROUND/AIM Geographic gradients in breast cancer incidence and mortality suggest that vitamin D may reduce risk. The enzyme 25-hydroxyvitamin D 24-hydroxylase (CYP24A1), which degrades the active form of vitamin D, and the vitamin D receptor (VDR) are both found in breast tissue. We investigated six polymorphisms in CYP24A1 and two in the VDR gene in association with breast cancer risk. M...

Folate and vitamin D have been shown to be influenced by ultraviolet (UV) radiation. UVA radiation can break down plasma folate, whereas vitamin D can be synthesized in UVB-exposed skin. Folate metabolism is involved in DNA synthesis and repair, and vitamin D processes anti-proliferative effects. The functions of both nutrients are implicated in skin carcinogenesis. We evaluated genetic polymor...

BACKGROUND & OBJECTIVES Malaria is a major public health problem in tropical and sub-tropical countries. Malaria vaccine is highly desirable as an adjunct to existing malaria control measures. The polymorphism in vaccine candidate antigens might be a hurdle in developing an effective vaccine. Merozoite surface protein-2, apical membrane antigen-1 and circumsporozoite protein of Plasmodium falci...

Background: The transversion of G to T (G894T) in human endothelial nitric oxide synthase (eNOS) gene has profound effects such as male infertility, recurrent miscarriage, multiple sclerosis and cardiovascular diseases.Objectives: Development of a new Multiplex Tetra-Primer Amplifi cation Refractory Mutation System - Polymerase Chain Reaction (T-ARMS-PCR) for detection of...

ThirtyFrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. Polymorphism of cow lactoferrin (LTF) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The results showed that LFT gene pro...

Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by enzymes. RFLP-PCR an easy-to-perform and inexpensive tool for initial analysis SNPs potentially associated with some monogenic diseases, as well in genotyping, genetic mapping, lineage screening, for...

Allele-specific polymerase chain reaction (AS-PCR) is a rapid and cost-effective single nucleotide polymorphism (SNP) genotyping method compared to multiplex or real-time PCR. The SNPs occurring in mitochondrial DNA (mtSNPs) the most abundant humans can be used human identification involving mass fatality incidents. Nevertheless, application of AS-PCR has yet widely applicable forensic investig...

We describe a modified single nucleotide polymorphism (SNP) typing method based on the restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR). This is a simple, economical method without the need for special equipment. For most SNP loci, a common restriction endonuclease (Hind III, EcoR I or BamH I) recognizing site (RER) can be introduced into one allelic form, but not t...
