The dendritic transport and local translation of mRNA may be an essential mechanism to regulate synaptic growth and plasticity. We investigated the molecular mechanism and function of beta-actin mRNA localization in dendrites of cultured hippocampal neurons. Previous studies have shown that beta-actin mRNA localization to the leading edge of fibroblasts or the growth cones of developing neurite...

Mesenchymal stem cells (MSCs) have been considered to have potential as ideal carriers for the delivery of anticancer agents since the capacity for tumor-oriented migration and integration was identified. In contrast to DNA-based vectors, mRNA synthesized in vitro may be readily transfected and is mutagenesis-free. The present study was performed in order to investigate the effects of phosphata...

Objective: To explore the mechanism of circRNA-vgll3 in osteogenic differentiation human bone marrow mesenchymal stem cells. Methods: BMSCs cells were transfected with circRNA-vgll3, and divided into high-level group, low-level negative control group (circRNA-vgll3 not transfected) according to amount transfection. The proliferation apoptosis osteoblasts each analyzed, alkaline phosphatase (ALP...

Here we report a method for efficient transfection of in vitro-transcribed mRNA into two different types of human adherent cells, the neuroblastoma cell line SK-N-AS, and the transformed kidney cell line HEK293. By using newly trypsinized adherent cells in suspension and Lipofectaminetrade mark 2000, we detected a transfection efficiency of 80-90% in both cell lines and a cell viability of 90% ...

Ultrasound‑targeted microbubble destruction (UTMD) can promote the entry of plasmid DNA (pDNA) into the cell cytoplasm, by increasing the permeability of the cell membrane. But the transfection efficiency remains low due to inability of the pDNA to enter the nucleus. Various methods have been explored to improve the UTMD transfection efficiency, but with little success. In cells, the classic nu...

early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributed to a change in the translational activity or stability of mrna in the egg and early embryo. as a result, translational control is critical for a variety of developmental decisions, including oocyte maturation and initiation of preimplantation development. in this s...

BACKGROUND Stent angioplasty provides a minimally invasive treatment for atherosclerotic vessels. However, no treatment option for atherosclerosis-associated endothelial dysfunction, which is accompanied by a loss of CD39, is available, and hence, adverse effects like thromboembolism and restenosis may occur. Messenger RNA (mRNA)-based therapy represents a novel strategy, whereby de novo synthe...

lipofectamine ltx is a cationic based transfection reagent that offers high levels of different transgenes expression in a huge number of cell types in vitro utilizing an easy and rapid protocol. the level of transgenes expression depend on some experimental variables containing cell density, lipofectamine and dna concentrations, lipofectamine -dna complexing time, and the presence or absence o...

background and aims: the aim of this study was cloning and expression of rabies virus glycoprotein by a eukaryotic expression plasmid pcdna3.1(+) in bsr cell line. this construct might be used for a potential dna vaccine. materials and methods: glycoprotein gene was synthesized and cloned into pbluescript vector and then sub cloned into eukaryotic expression vector (pcdna3.1(+)). after verifica...

The RECELL® Autologous Cell Harvesting Device enables point-of-care preparation of autologous skin cell suspension (ASCS). Currently, ASCS is approved for the treatment acute thermal burn injuries, with additional indications under investigation. We hypothesize therapeutic potential may be enhanced regeneration and primed rejuvenation by improving cells’ ability to divide differentiate reverse-...
