Background and Aim: Cytokines are believed to play an important role in the regulation of cellular immune response in hepatitis B virus infection. Interleukin 10 is a member of cytokine family. The overall expression of these molecules is mainly controlled by single nucleotide polymorphisms at specific sites on the promoter region of the Interleukin 10 gene. The aim of this study was to a...
Phylogenetic relationships and genetic variation between two Iranian sheep breeds were analyzed using cytochrome b (cyt-b) gene sequences. The genomic DNA was isolated by salting out method and amplified cytochrome b gene using polymerase chain reaction restriction (PCR) method with a pair of primer. A partial sequence of cyt-b gene of Iranian sheep is 780 bp and contained 13 variable sites and...
Background and Aim: Thalassemia, a heterogeneous disease, is one of the most common single-gene diseases worldwide. The aim of this study was to find associations between hematological indices and severity of beta-globin gene mutations in beta-thalassemia carriers. Materials and Methods: In this cross-sectional study, 30 beta-goblin gene mutations (b+ and b○) in 1206 unrelated beta-thalassemi...
Background and Aims: Avian infectious bronchitis virus (IBV) has a worldwide distribution and mutations occurring in the large viral genome of IBV have led to extensive antigenic variations among IBVs. This is the first study conducted to determine the complete membrane (M) gene sequences of different Iranian IBV genotypes. Materials and Methods: The M gene of three 793/B (IBKG1,6,7), one Mass...
Increased fetal hemoglobin (HbF) in b-globin gene disorders ameliorates the clinical symptoms of the underlying disease. 5-azacytidine, butyrate and hydroxyurea, have been shown to activate g-globin gene expression. It has also been found that hematopoietic growth factors can influence expression of g-globin in erythroid cultures and in animal models. This study was designed to evaluate the in ...
identification of genes affecting energy balance, milk yield and feed intake is an interesting area of researches in animal breeding. leptin gene polymorphism is associated with key economic affair. considering rich resources for animals, in our country, accomplishing a few assays to identify a gene that controls her traits with molecular genetics, and identifying the candidate genes in sheep b...
Background: B. thetaiotaomicron is introduced as a candidate for the next generation of probiotics. TLR2, 4 play an important and necessary role in activating and modulating the innate immune system after exposure to bacteria in the intestine. This study aimed to investigate the effect of B. thetaiotaomicron and its derivatives on the alteration of the tlr2 and tlr4 gene expression. Materials ...
background: haematophagous females of some phlebotomine sandflies are the only natural vectors of leishmania species, the causative agents of leishmaniasis in many parts of the tropics and subtropics, including iran. we report the presence of phlebotomus (larroussius) major and phlebotomus (adlerius) halepensis in tonekabon (mazanderan province) and phlebotomus (larroussius) tobbi in pakdasht...
infectious bronchitis (ib) disease is one of the important respiratory diseases of poultry that causes annually large economic losses in poultry industry of iran. the aim of this study is molecular characterization of s1 gene of iranian infectious bronchitis viruse (ibv) belonged to 793/b serotype. the whole s1 gene of three local ibv strains in rt-pcr, showed a band above 1600 base pair (bp) i...
