Accumulating evidence has identified a mechanism potentially responsible for the inactivation of tumor suppressor genes, namely transcriptional silencing by aberrant methylation of CpG islands. A previous study has shown the loss of RUNX3 expression, due to aberrant methylation of its CpG island, in gastric cancer cell lines, suggesting that RUNX3 is a(More)
In order to investigate proteins involved in early phase of conidia germination, proteomic analysis was performed using two-dimensional gel electrophoresis (2D-GE) in conjunction with MALDI-TOF mass spectrometry (MS). The expression levels of 241 proteins varied quantitatively with statistical significance (P<0.05) at the early phase of the germination(More)
The 4th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup was held in Vancouver, Canada, in June 2010. Representatives of 23 cooperative research groups studying gynecologic cancers gathered to establish international consensus on issues critical to the conduct of large randomized trials. Group C, 1 of the 3 discussion groups,(More)
Tardive dyskinesia (TD) is usually regarded as one of the most serious side-effects of the long-term usage of neuroleptics due to its high prevalence and potentially irreversible nature. Previously, several genetic polymorphisms were investigated for an association with TD in various ethnic populations. Among them, the Ser9Gly variant in the MscI(More)
Rho GDP dissociation inhibitor 2 (RhoGDI2) expression correlates with tumor growth, metastasis, and chemoresistance in gastric cancer. Here, we show that RhoGDI2 functions in the epithelial-mesenchymal transition (EMT), which is responsible for invasiveness during tumor progression. This tumorigenic activity is associated with repression of E-cadherin by(More)
BACKGROUND AND OBJECTIVES The incidence of thyroid gland involvement in laryngopharyngeal cancer ranges from 0 to 23%. Therefore, ipsilateral hemithyroidectomy and isthmusectomy are routinely performed with total laryngectomy in many clinics. Hemithyroidectomy causes hypothyroidism in 63% of patients, and if combined with radiotherapy, the incidence(More)
Gastric cancer is one of the most common cancers worldwide. The purpose of this study was to find out potential markers for gastric cancer. Tumor and normal tissues from 152 gastric cancer cases were analyzed by two-dimensional gel electrophoresis (2-DE). The images of silver stained gels were analyzed and statistical analysis of spot intensities revealed(More)
Rho GDP dissociation inhibitor (RhoGDI)2 has been identified as a regulator of Rho family GTPase. Recently, we suggested that RhoGDI2 could promote tumor growth and malignant progression in gastric cancer. In this study, we demonstrate that RhoGDI2 contributes to another important feature of aggressive cancers, i.e., resistance to chemotherapeutic agents(More)
Japanese common squid Todarodes pacificus collected from the East Sea/Sea of Japan were analyzed for cadmium, zinc and copper to elucidate the specific accumulation of heavy metals in various organs of squid of varying size and sex. There was no relationship between the size and sex of squid and the concentrations of heavy metals in various organs. Amongst(More)
Rho GDP dissociation inhibitor 2 (RhoGDI2) expression is correlated with tumor growth, metastasis and chemoresistance in gastric cancer. However, the mechanisms by which RhoGDI2 promotes tumor cell survival and metastasis remain unclear. In this study, we clearly demonstrate that RhoGDI2 upregulates VEGF-C expression and RhoGDI2 expression is positively(More)
