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)
Histone modification through acetylation and deacetylation is a key process in transcription, DNA replication, and chromosome segregation. During mitosis, histones are highly acetylated and chromatin is condensed. Here, we investigate the mechanistic involvement of histone deacetylase (HDAC) activity in the regulation of mitotic checkpoint activation.(More)
Despite the extensive studies on the roles of hepatitis B virus (HBV) X protein (HBx) in the development of hepatocellular carcinomas (HCCs), the mechanisms by which HBx contributes to HCC remain controversial. In this study, the effect of HBx on the G(1)-S checkpoint control depending on the status of p53 was compared. Transcription of p21(waf1/cip1) was(More)
Although end-binding protein 1 (EB1) is well known to regulate microtubule dynamics, the role of EB1 in apoptosis of non-small cell lung cancer (NSCLC) is poorly understood. Here, we investigated the molecular mechanism by which EB1 regulates apoptosis in H460, A549, and H1299 cells. Depletion of EB1 in A549 and H1299 cells, which express high levels of(More)
Although viral vectors are commonly used for therapeutic gene delivery, their applications are limited due to their specific cell membrane receptor-mediated infection and host immune response. In the present study, we constructed a non-viral peptide vector and applied it in the treatment of experimentally induced systemic lupus erythematosus-like disease in(More)
Neospora caninum is an important cause of abortion in cattle, and dogs are its only known definitive host. Its seroprevalence among domestic urban and rural dogs and feral raccoon dogs (Nyctereutes procyonoides koreensis) in Korea was studied by indirect fluorescent antibody test (IFAT) and by the neospora agglutination test (NAT), respectively. Antibodies(More)
Cancer stem cells (CSCs) are one of the main reasons behind cancer recurrence due to their resistance to conventional anti-cancer therapies. Thus, many efforts are being devoted to developing CSC-targeted therapies to overcome the resistance of CSCs to conventional anti-cancer therapies and decrease cancer recurrence. Differentiation therapy is one(More)
