PURPOSE Rho GDP dissociation inhibitor 2 (RhoGDI2) has been identified as a regulator of Rho family GTPase. However, there is currently no direct evidence suggesting whether RhoGDI2 activates or inhibits Rho family GTPase in vivo (and which type), and the role of RhoGDI2 in tumor remains controversial. Here, we assessed the effects of RhoGDI2 expression on(More)
Several studies examining the association between G72/G30 polymorphisms and schizophrenia in cohorts of various ethnic origins have recently been reported. The aim of the current study was to examine the genetic influence of the G72/G30 polymorphisms in the Korean population. Nine G72/G30 single-nucleotide polymorphisms (SNPs) were genotyped in 388 patients(More)
This study examined the association of the reticulon 4 receptor (RTN4R) gene with schizophrenia and smooth pursuit eye movement (SPEM) abnormality in a Korean population. Although we failed to provide convincing evidence that RTN4R is associated with schizophrenia development and SPEM impairment, our findings may be useful for further genetic studies.
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)
Inorganic pyrophosphatase (PPase) catalyzes the hydrolysis of pyrophosphate to form orthophosphate. Pyrophosphate can substitute for ATP under certain circumstances. We previously conducted a proteomic analysis to investigate tumor-specific protein expression in gastric cancer, and PPase was identified as a potential gastric tumor-specific marker; it was(More)
Schizophrenia is a multifactorial disorder characterized by the contribution of multiple susceptibility genes that may act in conjunction with epigenetic processes and environmental factors. The catechol-O-methyltransferase (COMT) gene, which is located in the 22q11 microdeletion, has been considered as a candidate gene for schizophrenia because of its(More)
BACKGROUND Invertebrates express regulatory receptors, transporters, and channels responsive to established drugs of abuse, many of which mediate their effects through catecholamine pathways. We hypothesized that invertebrate neural systems may serve as models by which to evaluate the interactive pharmacological effects of these agents. MATERIAL AND(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)
