Targeted mRNA degradation by short interfering RNAs (siRNAs) offers a great potential to treat cancers. siRNA therapeutics for leukemias are, however, hindered by poor intracellular uptake, limited blood stability and nonspecific delivery. To solve these problems, we developed an anti-JL1 immunonanoplex (antibody-coupled nanocomplex) for siRNA delivery(More)
BACKGROUND Ethnic and geographic differences exist in the prevalence of diabetes mellitus which has increased dramatically in South Korea. A few community-based epidemiologic studies with oral glucose tolerance test were performed in South Korea. The purpose of this study was to determine the prevalence of diabetes mellitus by the World Health Organization(More)
BACKGROUND Many patients report discomfort because of the unpleasant taste of bowel preparation solutions. OBJECTIVE This study aimed to determine whether adding orange juice to 2 L of polyethylene glycol plus ascorbic acid is effective for reducing patient discomfort and improving palatability during bowel preparation. DESIGN This was a single-blinded,(More)
PURPOSE Most chemical transfection reagents are ineffective for the transfection of cells in suspension, such as leukemic cell and stem cell lineages. We developed two different types of viroplexes, cationic Sendai F/HN viroplexes (CSVs) and protamine sulfate-condensed cationic Sendai F/HN viroplexes (PCSVs) for the efficient transfection of T-leukemic(More)
Arazyme is a metalloprotease released by Aranicola proteolyticus that was shown to inhibit cytokine release in HaCaT and endothelial cells. However, the regulatory effects of arazyme in atopic dermatitis remain to be fully understood. In the present study, the anti‑inflammatory effects of arazyme in BALB/c and Nc/Nga mice induced with(More)
Pancreatic polypeptide (PP) is a major agonist for neuropeptide Y4 receptors (NPY4R). While NPY4R has been identified in various tissues, the cells on which it is expressed and its function in those cells has not been clearly delineated. Here we report that NPY4R is present in all somatostatin-containing cells of tissues that we tested, including pancreatic(More)
BACKGROUND The effective delivery of therapeutic genes to target cells has been a fundamental goal in cancer gene therapy because of its advantages with respect to both safety and transfection efficiency. In the present, study we describe a tumor-directed gene delivery system that demonstrates remarkable efficacy in gene delivery and minimizes the(More)
Glioblastoma stem cells have been shown to confer chemoresistance and radioresistance, leading to angiogenesis and the recurrence of tumors in glioblastoma multiforme. Combination therapy targeting glioblastoma stem cells and anti-angiogenesis has been a focus of treatment strategies because of the enhanced efficacy achieved by dual inhibition of tumor(More)
Glioblostoma (GBM) cancer stem cells (CSCs) are considered to associating with glioblastoma cancer initiation, drug (or radio) resistance and malignancy. GBM CSCs, which are identified as subpopulation of CD133 + /ALDH1 + , are known to show resistance to the most of chemotherapy and radiation therapy [1]. Angiopep-2 (An2) is targeted ligand to Low density(More)
BACKGROUND Long-term expression of the delivered target gene is critical for successful gene therapy. Recently, hepatic control region I (HCR I) originating from the apolipoprotein (apo)C-I pseudogene was shown to be a critical element for long-term gene expression in the liver of mice. HCR II is another hepatic control region of apoC-I. METHODS HCR I,(More)
