Background and Aims : Mesenchymal stem cells (MSCs) are attractive targets for cell and gene therapy, because they can differentiate into many cell lineages. Hence, finding an efficient and suitable method for transferring of genetic materials to these cells is very essential. In this study, we evaluated the efficiency of two methods of gene transferring, viral and nonviral, in transfection...
background and objectives: during past decades hansenula polymorpha has attracted global attention for the expression of recombinant proteins due to its high growth rate, minimal nutritional porequirements and use of methanol as a low cost inducer. materials and methods: the corresponding nucleotide sequences for the expression of heterologous genes in hansenula poylmorpha were extracted and as...
To construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2), an Iranian isolate of HSV-2 was propagated in HeLa cell line and its DNA was extracted and used as template in polymerase chain reactions (PCR), to amplify gD2 gene. Primers were designed and the restriction enzyme sites for EcoRI and XhoI were considered at their 5′ ends respectiv...
Infectious Pancreatic Necrosis Virus (IPNV) is a member of the family Birnaviridae that has been linked to high mortalities in salmonids. Bacterial based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. VP2 is a structural viral protein of IPNV with immunogenicity effects. In this study IPNV was isolated from diseased fry ...
Introduction & Objective: Interleukine-1 receptor antagonist (IL-1RA) is a powerful anti-inflammatory cytokine which limits the biological effects of IL-1. Due to structural similarity between IL-1 and its antagonist, IL-1RA competitively binds to IL-1 receptor which leads to no signal transduction. Therefore , it is applied in the treatment of patients with inflammatory diseases such as Rheu...
Objective(s) Lipocalin 2 (Lcn2) is a 25-kDa glycoprotein that has initially been extracted from neutrophil granules. Expression of Lcn2 is induced under various pathophysiological conditions. It is also known as an early marker of kidney and heart injury. High-level expression of recombinant Lcn2 neutrophil gelatinase-associated(NGAL) in insect cells was the aim of this study. Materials and M...
Background: Safe and effective gene therapy is considered as one of the therapeutic goals in many diseases. Due to the important role of stem cells in cell therapy, this study aimed to produce human adipose-derived mesenchymal stem cells (hASCs) using the miR-34a overexpression. Materials and methods: The hsa-mir-34a precursor sequence was cloned into the PCDH lentiviral vector. The recombinant...
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...
objective(s): up to now, many researches have been performed to improve the antitumoral effect of melanoma differentiation-associated gene-7 (mda-7) protein. the purpose of our research was to construct 3 expression vectors producing mda-7 in fusion with rgd (arginine-glycine-aspartic acid) peptide and evaluate their expression. materials and methods: mda-7 gene with two different rgd seque...
