Background: DNA markers are inevitable tools of human identification in forensic science. Single Nucleotide Polymorphisms (SNPs) are one category of these markers which is concerned to use especially in the case of degraded DNA because of their short amplicons. Objectives: Detection of highly informative SNPs by the criteria is the essential step to devel...
Genotype imputation from low-density to high-density (SNP) chips is an important step before applying genomic selection, because denser chips can provide more reliable genomic predictions. In the current research, the accuracy of genotype imputation from low and moderate-density panels (5K and 50K) to high-density panels in the purebred and crossbred populations was assessed. The simulated popu...
Background: Tssk2, a member of the testis specific serine/threonine kinase (TSSK) family, is expressed predominantly in the testis and crucial for the formation and function of the sperm cells in mouse. Targeted deletion of Tssk1 and 2 in male chimeric mice caused infertility due to haploinsufficiency of the genes. Therefore it is reasonable to postulate that mutations in its human homologue TS...
Keratinocytes are non-professional immune cells contributing actively to innate immune responses partially by reacting to a wide range of molecular patterns by activating pattern recognition receptors. Cytosolic nucleotide fragments as pathogen- or self-derived trigger factors are activating inflammasomes and inducing anti-viral signal transduction pathways as well as inducing expression of inf...
Purpose: Estrogen as a crucial hormone during pregnancy acts by two types of receptors. Estrogen receptor alpha, expressed by estrogen receptor 1 (ESR1) gene, is more abundant and exists in all human reproductive systems. Association of ESR1 gene polymorphism has been shown in some reproductive fields such as spontaneous abortion, endometriosis-related infertility and in vitro fertili...
Background: Insulin resistance and progressive β-cells failure are the key factors in type 2 diabetes mellitus (T2DM) pathogenesis. Many studies support a primary role of RBP4 in insulin resistance and suggest that genetic variations which alter the expression level of RBP4 might influence the risk of T2DM and its complications. Diabetic foot is one of the main complications of diabetes le...
Background: CDKN2A, encoding two important tumor suppressor proteins p16 and p14, is a tumor suppressor gene. Mutations in this gene and subsequently the defect in p16 and p14 proteins lead to the downregulation of RB1/p53 and cancer malignancy. To identify the structural and functional effects of mutations, various powerful bioinformatics tools are available. The aim of this study is the ident...
Ramie (Boehmeria nivea L.) bast fiber is one of the most ancient natural fibers, which used for textile only after degumming. Hemicellulose, pectin, and hydrotrope are main colloidal matters in ramie fiber, removed when However, genetic variation control loci poorly understood. Here, we analyzed discovered favorable single nucleotide poly morphisms (SNP) by genome-wide association study using 3...
Resistance to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd. & Syd., has been identified in many soybean germplasm accessions and is conferred by either dominant or recessive genes that have been mapped to six independent loci (Rpp1 -Rpp6), but No U.S. cultivars are resistant to SBR. The cultivar DT 2000 (PI 635999) has resistance to P. pachyrhizi isolates and field populations from t...
