A total of 39 water samples from 23 different groundwater wells in Korea were collected and analyzed in order to monitor the occurrence of norovirus (NoV) and other indicator microbes as the first part of a national survey of groundwater. More than 500 L of untreated groundwater were filtered through 1MDS filters. Following elution and concentration by(More)
Pancreatic cancer is highly aggressive, malignant, and notoriously difficult to cure using conventional cancer therapies. These conventional therapies have significant limitations due to excessive extracellular matrix (ECM) of pancreatic cancer and poor cancer specificity. The excess ECM prevents infiltration of drugs into the inner layer of the solid(More)
The Hsp70 family protein mortalin is an essential chaperone that is frequently enriched in cancer cells and exists in various subcellular sites, including the mitochondrion, plasma membrane, endoplasmic reticulum, and cytosol. Although the molecular mechanisms underlying its multiple subcellular localizations are not yet clear, their functional significance(More)
BACKGROUND Gene-based virotherapy mediated by oncolytic viruses is currently experiencing a renaissance in cancer therapy. However, relatively little attention has been given to the potentiality of dual gene virotherapy strategy as a novel therapeutic approach to mediate triplex anticancer combination effects, particularly if the two suitable genes are well(More)
Owing to the lack of practical cell culture system for human noroviruses (HuNoV), various detection methods based on conventional reverse transcription-PCR (RT-PCR) and the quantitative real-time PCR have been major tools for monitoring environmental water safety. In this study, we showed that the proportion of water sample concentrates used for one-step(More)
Adenovirus (Ad) is a widely used vector for cancer gene therapy but its therapeutic efficacy is limited by low coxsackievirus and adenovirus receptor (CAR) expression in tumors and non-specifically targeted infection. Ad infectivity and specificity can be markedly improved by creating Ad-magnetic nanoparticles cluster complexes and directing their migration(More)
Adenovirus (Ad) is a potential vehicle for cancer gene therapy. However, cells that express low levels of the coxsackie and adenovirus receptor (CAR) demonstrate poor Ad infection efficiency. We developed a bile acid-conjugated poly(ethyleneimine) (DA3)-coated Ad complex (Ad/DA3) to enhance Ad transduction efficiency. The size distribution and zeta(More)
Erratum Unfortunately, the original version of this article [1] contained an error. One of the subheadings within the " Methods " section read " Generation and purification of oncolytic adenoviruses expressing human TRAIL or human ING4 transgene " , but it should have read " Generation and purification of oncolytic adenoviruses expressing human TRAIL or(More)
O1 Regulation of genes by telomere length over long distances Jerry W. Shay O2 The microtubule destabilizer KIF2A regulates the postnatal establishment of neuronal circuits in addition to prenatal cell survival, cell migration, and axon elongation, and its loss leading to malformation of cortical development and severe epilepsy Noriko Homma, Ruyun Zhou,(More)
Despite adenovirus (Ad) vector's numerous advantages for cancer gene therapy, such as high ability of endosomal escape, efficient nuclear entry mechanism, and high transduction, and therapeutic efficacy, tumor specific targeting and antiviral immune response still remain as a critical challenge in clinical setting. To overcome these obstacles and achieve(More)
