Runx3/Pebp2alphaC null mouse gastric mucosa exhibits hyperplasias due to stimulated proliferation and suppressed apoptosis in epithelial cells, and the cells are resistant to growth-inhibitory and apoptosis-inducing action of TGF-beta, indicating that Runx3 is a major growth regulator of gastric epithelial cells. Between 45% and 60% of human gastric cancer(More)
Magnetic nanoparticles for applications in separation and purification processes must satisfy several basic requirements. They should be superparamagnetic, i.e. possess low coercivity (H c) and low retentivity (M r), to enable re-dispersion after magnetic capture. In this study, the synthesis of SiO 2 coated γ-Fe 2 O 3 nanocomposite particles has been(More)
Leucine-rich repeat-containing 3B (LRRC3B) is an evolutionarily highly conserved leucine-rich repeat-containing protein, but its biological significance is unknown. Using restriction landmark genomic scanning and pyrosequencing, we found that the promoter region of LRRC3B was aberrantly methylated in gastric cancer. Gastric cancer cell lines displayed(More)
The mitotic spindle checkpoint plays a crucial role in regulating accurate chromosome segregation and preventing the adaptation of multiploid progeny cells. Recent reports have indicated that the induction of p53 by mitotic checkpoint activation is essential for protecting cells from abnormal chromosome ploidization caused by mitotic failure. However,(More)
STAT4, which plays a pivotal role in Th1 immune responses, enhances IFN-gamma transcription in response to the interaction of IL-12 with the IL-12R. Mice deficient in STAT4 lack IL-12-induced IFN-gamma production and Th1 differentiation and display a predominantly Th2 phenotype. Although these findings indicate that STAT4 expression levels are important for(More)
MAD2 is localized to kinetochores of unaligned chromosomes, where it inactivates the anaphase-promoting complex/cyclosome, thus contributing to the production of a diffusible anaphase inhibitory signal. Disruption of MAD2 expression leads to defects in the mitotic checkpoint, chromosome missegregation, and tumorigenesis. However, the mechanism by which(More)
Here, we demonstrate that electroporation-enhanced immunization with a rationally designed HPV DNA vaccine (GX-188E), preferentially targeting HPV antigens to dendritic cells, elicits a significant E6/E7-specific IFN-γ-producing T-cell response in all nine cervical intraepithelial neoplasia 3 (CIN3) patients. Importantly, eight out of nine patients exhibit(More)
