Adenoviral vector mediated gene delivery has been applied in clinical trials and mechanistic studies to explore new treatment approaches for lung cancers. The expression of coxsackievirus adenovirus receptor (CAR), the primary receptor for the most commonly used adenovirus serotype 5 (Ad5)-based vectors, predominantly determines the permissiveness of lung(More)
"Cell type-and region-dependent coxsackie adenovirus receptor expression in the central nervous system." Abstract Model systems have shown that adenoviral vector mediated transient gene expression can potentially be applied for the treatment of brain tumours, neurodegenerative diseases and brain injuries. Most studies utilized adenovirus serotype 5 (Ad5)(More)
Deoxynivalenol (DON) is one of the most common mycotoxin contaminants of raw and processed cereal food. Lymphoid cells and fibroblasts are specified to be the most DON-sensitive cell types. In this study, we investigated the toxic effects of DON in chicken embryo fibroblast DF-1 cells. The results showed that DON significantly inhibited DF-1 cell viability(More)
Gliomas, in particular the high-grade anaplastic glioma and glioblastoma multiforme (GBM), are manifested by morphological, genetic and phenotypic heterogeneity. Most of the studies hitherto have been performed on bulk glioma cells, with limited understanding on the origin and the relative contribution of particular glioma cell populations to glioma growth(More)
BACKGROUND & AIMS S100A4 has been linked to the fibrosis of several organs due to its role as a fibroblast-specific marker. However, the role of S100A4 itself in the development of fibrosis has not been much investigated. Here, we determined whether S100A4 regulates liver fibrogenesis and examined its mechanism by focusing on the activation of hepatic(More)
BACKGROUND While neurosphere- as well as xenograft tumor-initiating cells have been identified in gliomas, the resemblance between glioma cells and neural stem/progenitor cells as well as the prognostic value of stem/progenitor cell marker expression in glioma are poorly clarified. METHODOLOGY/PRINCIPAL FINDINGS Viable glioma cells were characterized for(More)
Human adenovirus (Ad) serotypes Ad3, Ad7, Ad11, and Ad14, as well as a recently emerged strain of Ad14 (Ad14p1), use the epithelial junction protein desmoglein 2 (DSG2) as a receptor for infection. Unlike Ad interaction with CAR and CD46, structural details for Ad binding to DSG2 are still elusive. Using an approach based on Escherichia coli expression(More)
BACKGROUND A paucity of coxsackie adenovirus receptor (CAR) hampers the adenovirus serotype 5 (Ad5)-based vector-mediated gene transfer into malignant hematopoietic cells. Fiber-retargeted adenoviral vectors with species B tropism can potentially bypass the CAR requirement and facilitate efficient gene transfer into malignant hematopoietic cells. METHODS(More)
Telomerase activity has been suggested to be critically involved in hematopoietic stem cell (HSC) self-renewal. However, it has been unclear whether human HSCs have telomerase activity and how telomerase activity is regulated within the HSC and progenitor pool. Here, we isolated living cord-blood (CB) CD34(+) cells with up-regulated human telomerase reverse(More)
