The purpose of this study was to investigate the expression level of miR-146a and miR-155 in cardiac xenograft models treated with immunosuppressant FK506, and to construct lentiviral vectors to further study the role of miR-146a and miR-155 in cardiac xenotransplantation. the expression levels of miR-146a and miR-155 is checked by quantitative polymerase chain reaction analysis and protein expression RELA, which is a member of the family of nuclear factor-kB, is checked by western blot analysis. Pre-miR-146a and miR-155 pre-designed and synthesized fragments according to MiRBase and cloned into plasmid pCDH1-MCS1-EF1-copGFP. recombinant plasmids were identified by enzyme digestion and sequencing.
Heart transplant survival time in FK506 treatment group increased significantly compared with the control group (P <0.05). In addition, the results of the histopathological grading was significantly decreased in the treatment group (P <0.05). A significant reduction in the level of protein expression Rela observed in the treatment group (P <0.05), along with a significant increase in the level of miR-146a expression (P <0.05) and a significant reduction in miR-155 expression levels ( P <0.05).
Digestion and sequencing findings suggest that miRNA insertion into plasmid pCDH1-MCS1-EF1-copGFP in accordance with pre-miRNAs, and concentrated into a lentiviral vector titer of 5 x 107 IFU / ml. These findings indicate that FK506 is able to inhibit the effect of rejection in cardiac xenotransplantation model of rat-to-rat. FK506 treatment alter the expression level of miR-146a and miR-155, which indicates that they may have an important role in regulating the immune response to the effects of rejection. miR-146a and miR-155 successfully constructed lentiviral vectors for further experiments both in vitro and in vivo.
Initial graft size and not the innate immune response limit survival of engrafted neural stem cells.
Formulation Nonionic Surfactant vesicles (NISV) Prepared by Microfluidics for Therapeutic Delivery of siRNA into cancer cells.
Disturb small RNA (siRNA) has a vast potential as a therapeutic agent for reversible silencing of target genes anything interesting. The clinical application of siRNA requires the use of safe and effective delivery system. In this study, we investigated the use of non-ionic surfactant vesicles (NISV) for siRNA delivery. Various types of formulations NISV microfluidic synthesized by mixing and then evaluated for cytotoxicity and physiochemical properties.
NISV ability to carry and transfect siRNA targeting the green fluorescent protein (GFP) to the A549 that stably express GFP (copGFP-A549) were evaluated. Flow cytometry and Western blotting were used to study the expression of GFP knockdown, and significant knockdown was observed as a result of the delivery of siRNA into cells by NISV. This happens especially when using Tween 85, which is capable of reaching more than 70% GFP knockdown. NISV thus shown to provide a promising and effective platform for the delivery of siRNA therapies.The application of stem cells in the treatment of various degenerative diseases are very promising.

Description: Eukaryotic histones are basic and water-soluble nuclear proteins that form hetero-octameric nucleosome particles by wrapping 146 base pairs of DNA in a left-handed super-helical turn sequentially to form chromosomal fiber. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form the octamer; formed of two H2A-H2B dimers and two H3-H4 dimers, forming two nearly symmetrical halves by tertiary structure. Over 80% of nucleosomes contain the linker Histone H1, derived from an intronless gene that interacts with linker DNA between nucleosomes and mediates compaction into higher order chromatin. Histones are subject to posttranslational modification by enzymes primarily on their N-terminal tails, but also in their globular domains. Such modifications include methylation, citrullination, acetylation, phosphorylation, sumoylation, ubiquitination and ADP-ribosylation.

However, the cell-based therapies can be limited by the problem of low survival of cells grafted and uncertainty about their fate. The combination of molecular imaging and contrast-enhanced MRI can provide more insight into the survival and behavior of transplanted stem cells. We explored the hair-follicle stem cell-derived bulge (HFBSCs) as a potential candidate for autologous cell-based therapies. HFBSCs were transduced with lentiviral construct to the gene coding for the bioluminescent (Luc2) and fluorescent (copGFP) reporter protein, and then loaded with magnetic nanoparticles to enable MRI visualization.
