Recent advances in the synthesis of multi-functional nanoparticles have opened up tremendous opportunities for the targeted delivery of genes of interest. Cationic solid lipid nanoparticles (SLN) can efficiently bind nucleic acid molecules and transfect genes in vitro. Few reports have combined SLN with therapy using decoy oligodeoxynucleotides (ODN). In the present study, we prepared SLN to en...
Unmethylated cytosine-phosphorothioate-guanine (CpG) containing oligodeoxynucleotides (CpG-ODN) are known to act as adjuvants and powerful activators of the innate immune system. We investigated the therapeutic effect of CpG-ODN on a variety of established mouse tumors including AG104A, IE7 fibrosarcoma, B16 melanoma, and 3LL lung carcinoma. These tumors are only weakly immunogenic and notoriou...
The aim of the present study was to investigate the effect of CpG-oligodeoxynucelotides (CpG-ODN) on the proliferation of the A549 human lung adenocarcinoma cell line and the expression of Runt-related transcription factor 3 (Runx3) and investigate the association between the toll-like receptor 9 (TLR9) signaling pathway and Runx3 expression during A549 cell proliferation. Different concentrati...
Microinjection of oligodeoxynucleotides (ODNs) complementary to cellular mRNAs has been advanced as an experimental approach to degrade target mRNAs in vivo and thereby obtain information as to the function of their cognate proteins. It is shown here that ODNs can induce a variety of aberrations in cell metabolism and structure when injected into Xenopus oocytes. Examination of histological sec...
PURPOSE Laparoscopic donor nephrectomy is associated with less postoperative pain and faster recovery times in living kidney donors. However, pneumoperitoneum, which is required in laparoscopic donor nephrectomy, can result in adverse effects on renal function in donors and recipients. We compared renal function in donors and recipients after hand-assisted laparoscopic donor nephrectomy (HALDN)...
We used an antisense oligonucleotide (ODN) to inhibit laminin (LM) beta1 chain synthesis in mouse embryonic lung explants and cell cultures. The ODN spanned 17 bases located 13 bases downstream the initiation codon and contained phosphorothioate and C-5 propynyl pyrimidine modifications. Penetration of the ODN into the lung explants was confirmed by fluorescein isothiocyanate (FITC) tagging. 50...
Periodontitis is a chronic infectious disease for which the fundamental treatment is to reduce the load of subgingival pathogenic bacteria by debridement. However, previous investigators attempted to implement a nuclear factor kappa B (NF-κB) decoy oligodeoxynucleotide (ODN) as a suppressor of periodontitis progression. Although we recently reported the effectiveness of the ultrasound-microbubb...
Oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODN) mimic the immunostimulatory activity of microbial DNA by interacting with Toll-like receptor 9 (TLR9) to activate both the innate and adaptive immune responses in different species. However, few studies have been published to compare the effects of CpG ODN on different pig breeds. Therefore, in this study, whole blood gene expre...
OBJECTIVES The excess proliferation of vascular smooth muscle cells (VSMCs) and the development of intimal hyperplasia is a hallmark of vein graft failure. This study aimed to verify that a single intraoperative transfection of early growth response gene-1 (Egr-1) decoy oligonucleotide (ODN) can suppress vein graft proliferation of VSMCs and intimal hyperplasia. METHODS In a rabbit model, jug...
Synthetic oligonucleotides containing repetitive TTAGGG motifs mimic the immunosuppressive activity of telomeric DNA. These suppressive oligonucleotides (Sup ODN) are effective in the treatment/prevention of various inflammatory and autoimmune diseases in mice. The therapeutic activity of Sup ODN was originally attributed to the inhibition of Th1 cell activation. Current results indicate that S...
