Alteration of adipocyte function contributes to the pathogenesis metabolic diseases including Type 2 diabetes and insulin resistance. This highlights need better understand molecular mechanism involved in dysfunction develop new therapies against obesity-related diseases. Modulating expression proteins micro-RNAs adipocytes remains highly challenging. paper describes a protocol differentiate mu...
When comparing the ability of two sequences to regulate the expression of a reporter gene, following transfection of cells in cultures, it is necessary to control for the potential difference in transfection efficiency. This is done by either conducting the experiment several times with at least two different preparations of each DNA or by adding a second plasmid (internal control plasmid) enco...
It has been believed that nuclear gene delivery is the most important process for gene expression, and various non-viral vectors are currently being developed with this assumption. However, some of our earlier studies revealed a surprising difference in transfection activity between viral and non-viral vectors: this difference is largely due to the result of the intranuclear disposition of DNA ...
Background: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...
Background: The magnetic nanoparticle-based transfection method is a relatively new technique for delivery of functional genes to target tissues. We aimed to evaluate the transfection efficiency of rat neural stem cell (NSC) using poly-L-lysine hydrobromide (PLL)-coated super paramagnetic iron oxide nanoparticles (SPION). Methods: The SPION was prepared and coated with PLL as transfection agent...
conclusions therefore the non-infectious dlps were became infectious if introduced into the cytoplasm of permissive and cancerous cells, without passing attachment and entry process. results we attempt to avoid the attachment and entry of the rotavirus by using lipofectamine to mediate the delivery of viral particles directly into the cytoplasm. dlp was endocytosed into the cytoplasm following ...
The DNA transfer efficiency in liposomal versus viral transfection is very low, mainly due to an insufficient nuclear transport of the delivered DNA after its endocytotic uptake to the cell. Ligand activation of intracellular steroid receptors and their subsequent mobilization to the nucleus could result in a co-transport of DNA to the nucleus. The augmentation of nuclear transport of DNA after...
A sphingosine kinase (SPHK) type 2 inhibitor, SG-12, inhibited the SPHK2 activity in A20/2J cells and promoted Fas-dependent cell death. The effect of SG-12 on cell death was relieved by SPHK2 transfection but not by SPHK1 transfection. The results suggest a SPHK2-specific suppression of Fas-dependent cell death.
