background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...

Induction of protein synthesis by the external delivery of in-vitro transcription-messenger RNA (IVT-mRNA) has been a useful approach in the realm of cell biology, disease treatment, ‎reprogramming of cells, and vaccine design. Therefore, the development of new formulations for ‎protection of mRNA against nucleases is required to maintain its activity in-vivo. It was the aim o...

The integrated proviral DNA of avian sarcoma virus (ASV) in host cell chromosomes has been isolated and stored in saline sodium citrate (SSC) solution or in 70% ethanol at 4 degrees C in a refrigerator over 4 years. This DNA was assayed by transfection of chick embryo cells(CEC). The biological activity of cellular transformation by the stored DNA was compared with that of a fresh isolate of th...

Objective(s): Various studies have been conducted to reduce the metastatic behavior of cancerous cells. In this regard, ectopic expression of anti-metastatic microRNAs by miR-mimic and miR-restoration-based therapies could bring new insights to the field. In the present study, the consequences of co-transfecting breast cancer cell lines with miR-193b and miR-31 were investigated via invasion an...

Background: Low uptake of exogenous DNA by sperm and reduced number of fertilized oocyte by transfected sperm are the major obstacles for progression of sperm mediated gene transfer. Therefore, the modification of sperm mediated gene transfer procedure needs to be required. The purpose of this study was to evaluate the efficiency of FuGene 6 compare to lipofection in transfection medium for int...

introduction: neurotrophins, as a family of proteins, are responsible for induction of the survival, development, and function of neurons. also, neurotropic factors are growth factors like neurotrophins that help neurons survive. moreover, neurotrophins differentiate between progenitor cells so that neurons are formed. despite the fact that the majority of mammalian brain neurons are produced p...

application of therapeutic gene transfer in the treatment of genetic diseases is a notable progress but there are some disadvantages and limitations in it. the process of overcoming these barriers is a drastic change in gene delivery. recently, calcium phosphate nanoparticles alone, or in combination with viral and nonviral vectors, were found to have a positive effect on gene transfer especial...
