Background and purpose: Toxoplasma gondii (T. gondii) is an obligatory intracellular protozoan parasite. Toxoplasmosis is highly prevalent and has a great effect on public health, therefor, there is a need for vaccine and sensitive diagnostic procedures. This study aimed at cloning and investigating the expression of ROP13 gene of T. gondii. Materials and methods: In this study, the gene was c...
Introduction & Objective: Vacuolar proteinase is an aspartic enzyme in Candida albicans (C. albicans) that is expressed by VAP gene and plays an important role in the development of systemic candidiasis. The aim of this study was to evaluate VAP gene expression in C. albicans strains isolated from patients with systemic candidiasis. Materials & Methods: The evaluation of VAP gene expression ...
Background and Objective: The severity of the spinal muscular atrophy phenotype is inversely associated with the expression levels of the SMN2 gene; this correlation is not absolute, for this reason there is currently no effective treatment. The interference of other severity modifying factors, apart from SMN2 gene expression has been suggested. Here we investigate the effects of valproic acid ...
Introduction: One of the most important complications of exposure to noises is changes in the gene expression patterns. Irreversible damage to the inner ear, such as noise-induced hearing loss (NIHL), is caused by tissue damage and changes in the gene expressions in the auditory system. Changes in the GJB2 gene expression pattern lead to autosomal deafness at different loci. The present study a...
Background: In gene therapy, the use of RNA molecules as therapeutic agents has shown advantages over plasmid DNA, including higher levels of safety. However, transient nature of RNA has been a major obstacle in application of RNA in gene therapy. Methods: Here, we used the internal ribosomal entry site of encephalomyocarditis virus and the 3’ non-translated region of Poliovirus to design an en...
Background and Objectives: Helicobacter pylori is a gram-negative and spiral bacterium that causes stomach and duodenal disease in humans. Because of the presence of disadvantages in antibiotic therapies, increasing efforts have been made to produce effective vaccine for this infection. The aim of this study was to generate a construct carrying the lnT gene and to survey its...
Gene transfer to plants and the production of transgenic plants with various purposes, such as improving the performance and quality, resistance to pests, diseases, etc., and of great importance are carried out Gene transfer to plants performs to evaluate the transient and permanent gene expression. Transient expression is quick, easy and simple and is not influenced by position effect compare ...

Background and Aim: As one of the factors of gastric ulcers and cancer, Helicobacter pylori can live in the acidic environment of stomach for many years due to having urease enzyme. This enzyme requires Ni2+ and a group of auxiliary proteins such as ureE for its catalytic activity. Urease is not only a requisite factor to colonize the Helicobacter pylori but it is also pathogenic with diff...
3,4- Methylenedioxymethamphetamine (MDMA or "Ecstasy") is a psychoactive and hallucinogenic drug of abuse. MDMA has been shown to produce neurotoxicity both in animals and humans. Recently, the vasodilator drugs such as pentoxifylline is one of the new strategies which have been considered as neuroprotector. In this study effect of pentoxifylline on bcl-2 gene expression changes in hippocampus ...
