Neonates suffer high morbidity and mortality in infection, presumably because of the lack of a fully developed adaptive and innate immune system. Evidence of poor innate responses in neonates has been shown by using a model that sensitizes the host to Toll-like receptor (TLR)-mediated inflammation with d-galactosamine (d-GalN). However, we show that(More)
Thioredoxin (Trx) is a cellular redox enzyme that plays multiple roles in regulating cell growth and apoptosis. Jun activation domain-binding protein 1 (Jab1) was originally identified as a coactivator of activator protein 1 (AP-1) transcription and was also shown to promote degradation of the cyclin-dependent kinase inhibitor, p27Kip1. Recently, Jab1(More)
Collagen triple helix repeat-containing 1 (CTHRC1) is known to be aberrantly upregulated in most human solid tumors, although the functional roles of CTHRC1 in colorectal cancer remain unclear. In this study, we investigated the occurrence of CTHRC1 upregulation and its role in vivo and in vitro. The expression profile and clinical importance of CTHRC1 were(More)
Neuraminidase is a proven target in anti-viral drug development. It also appears to be important for infection by certain pathogenic bacteria and has been implicated in biofilm formation. Based on activity-guided fractionation, the acetone extract of Amorpha fruticosa roots gave four flavanones 1-4 and three rotenoids 5-7 which were identified as amoradicin(More)
Toll-like receptors (TLRs) recognize conserved microbial structures called pathogen-associated molecular patterns. Signaling from TLRs leads to upregulation of co-stimulatory molecules for better priming of T cells and secretion of inflammatory cytokines by innate immune cells. Lymphocyte-deficient hosts often die of acute infection, presumably owing to(More)
Based on a previous finding that endothelial cell-specific molecule-1 (ESM-1) is a potential serum marker for colorectal cancer (CRC), the aim of this study was to clarify the clinicopathological significance of ESM-1 expression in CRC, and to explore the correlation between ESM-1 and HIF-1α in the tumorigenesis of(More)
We searched for genes with expressions specific to human monocyte-derived dendritic cells (DCs) using differential display reverse transcription-polymerase chain reaction, and found that N-myc downstream regulated gene 2 (NDRG2), a member of a new family of differentiation-related genes, was expressed in DCs. While DCs derived from CD34(+) progenitor cells(More)
The efficacy of cisplatin in cancer chemotherapy is limited by the development of resistance. To elucidate the molecular basis of resistance to cisplatin, we compared cisplatin-induced apoptotic responses of the parental human bladder cancer cell line, T24 and its resistant subclone, T24R2. In T24 cells, cisplatin induce apoptosis and the activation of(More)
We reported previously that N-myc downstream-regulated gene 2 (NDRG2), a member of a new family of differentiation-related genes, is expressed specifically in dendritic cells (DC) differentiated from monocytes, CD34(+) progenitor cells, and the myelomonocytic leukemic cell line. In this study, we demonstrate that NDRG2 protein expression is detected, not(More)
DNA gyrase, which catalyzes topological transformation of DNA, plays an essential role in replication and transcription in prokaryotes. Virus-induced gene silencing of NbGyrA or NbGyrB, which putatively encode DNA gyrase subunits A and B, respectively, resulted in leaf yellowing phenotypes in Nicotiana benthamiana. NbGyrA and NbGyrB complemented the gyrA(More)
