vascular endothelial growth factor -2578c/a polymorphism and colorectal cancer risk: a meta-analysis
background: the effects of the vascular endothelial growth factor (vegf) gene ?2578c/a polymorphism on colorectal cancer (crc) risk have been investigated in some studies; however, the results of these studies were conflicting and ambiguous. therefore, we aimed to do a meta-analysis to investigate the association of vegf ?2578c/a polymorphisms with crc risk from all eligible case-control studie...
Introduction: Spermatogenesis is a strictly regulated process in sperm production that is needed for sperm production transcriptional and posttranscriptional regulations. The cytoplasmic polyadenylation element binding (CPEB) protein regulates cytoplasmic polyadenylation of mRNAs in oogenesis and spermatogenesis. The purpose of the present studywas examining the association between rs2303846, ...
Objective(s): Mutations in the UGT1A1 gene are responsible for hyperbilirubinemia syndromes including Crigler-Najjar type 1 and 2 and Gilbert syndrome. In view of the genetic heterogeneity and involvement of large numbers of the disease causing mutations, the application of polymorphic markers in the UGTA1 gene could be useful in molecular diagnosis of the disease. Materials and Methods: In the...
Grain hardness is the main factor for classification and end-use quality of wheat. Wheat with the hard grain texture has higher protein content and more intensive gluten that leads to production of higher bread quality. However, soft texture wheat has lower protein content and weaker gluten, which are suitable for cake and candy production. Grain hardness is determined by the Pina and Pinb gene...
Background and Aim: Colorectal cancer is one of the most common malignancies in worldwide. Because the gene 5, 10-methylene-tetrahydrofolate reductase (MTHFR) plays a key role in methylation, synthesis and repair of DNA, numerous studies have focused on evaluating the correlation between polymorphisms of this gene and sporadic colorectal cancer. This study was carried out to examine the associa...
Background: Individuals respond to statins differently due to genetic variations. One of the most significant enzymes involved in drug metabolism is CYP2D6 enzyme, coded by the CYP2D6 gene. Individuals who carry two non-functional alleles in this gene are considered as poor metabolizers (PMs). Recognizing poor metabolizers might help in preventing adverse effects of drugs. Objective: In this ...
The black sparrowhawk (Accipiter melanoleucus) is a color-polymorphic sub-Saharan raptor, with adults occurring in two discrete color morphs: dark and light. It has previously been suggested that plumage coloration determined by one-locus two-allele system, the light allele being dominant over allele. Here, we revisit assumption an extended dataset of 130 individuals pedigree information from 7...
quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. reports name the acyl coa: diacylglycerol acyltransferase (dgat1) gene as a potential candidate gene with dinucleotide substitution (aa to gc) in exon viii which causes the change of lysine to alanine in amino acid (k232a).the aim of the present study was to estimate the frequency...
wheat is a crop with spring and winter types and wide adaptability to different climate conditions. the wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (vrn) genes play pivotal role in determining spring and winter types. in this study, 395 iranian wheat landraces were characterized with specific primer pairs designed based on vrn-...
