Abstract Background and objectives: Breast cancer is the most prevalent one in women. Some of the common causative factors are genetic background, nutritional and environmental factors. Viruses are believed as a risk factor in this cancer, too. Recent studies reported that Human Papillomaviruses can be one of the possible risk factors of breast cancer. This study focused on investigation of the...

Background and Aims: Borna disease virus (BDV) is well known as a neurotropic virus, however, its role in human neurological diseases such as schizophrenia and bipolar disorder is still unclear. In this study, we aimed to investigate the BDV genome in such patients in Golestan province, North of Iran. Materials and Methods: RNA was extracted from peripheral blood mononuclear cells (PBMCs) from...

The recent development of homologous recombination-mediated gene targeting (GT) techniques has made it easy to modify nucleotide sequences in plant genomes. Backcross breeding following GT provides transgene-free lines with high probability. However, owing the possibility unintentional transgene introduction during genetic transformation, analytical methods may be necessary reliably and compreh...

Linkage disequilibrium (LD) is bases of genomic selection, genomic marker imputation, marker assisted selection (MAS), quantitative trait loci (QTL) mapping, parentage testing and whole genome association studies. The Particular alleles at closed loci have a tendency to be co-inherited. In linked loci this pattern leads to association between alleles in population which is known as LD. Two metr...

Background and Aims: Crimean-Congo hemorrhagic fever (CCHF) is a fatal viral disease that occurs in approximately 30 countries. It has the most extensive geographic range among the tick-borne viruses that affect human health. CCHF viruses have a tripartite RNA genome consisting of large (L), medium (M) and small (S) segments. This study was undertaken to determine the genetic relationship of CC...

Introduction: Hepatitis G virus is an RNA virus related to Flaviviridae family that its genome was identified in the patients with non A-E hepatitis at the end of the last century. The present study aimed to investigate the survey of the prevalence of hepatitis G in blood donors and its relation to age and gender Methods: In this descriptive cross-sectional study, sampling was performed on 263...

Objective(s): Oncolytic Herpes simplex virus type 1 (HSV-1) has emerged as a promising strategy for cancer therapy. However, development of novel oncolytic mutants has remained a major challenge owing to low efficiency of conventional genome editing methods. Recently, CRISPR-Cas9 has revolutionized genome editing.Materials and Methods: I...

Abstract Powdery mildew disease caused by Oidium arachidis poses a threat to peanut production in Africa. Loss of function mutants specific Mlo (Mildew Locus O) genes have provided broad-spectrum and durable resistance against pathogen many crop species. Since there is huge potential utilize susceptibility gene-mediated improvement, genome-wide mining required for further researches. However, t...
