Metastatic tumor antigen 1 (MTA1) is known to play a role in angiogenic processes as a stabilizer of hypoxia-inducible factor 1-alpha (HIF1-alpha). In this study, we examined whether overexpression of MTA1 affects the recurrence of hepatocellular carcinoma (HCC) after surgical resection and the survival of the patients. A total of 506 HCC patients who(More)
The incidence of amyloid plaques, composed mainly of beta-amyloid peptides (Abeta), does not correlate well with the severity of neurodegeneration in patients with Alzheimer's disease (AD). The effects of Abeta(42) on neurons or neural stem cells (NSCs) in terms of the aggregated form remain controversial. We prepared three forms of oligomeric, fibrillar,(More)
Tyrosinase is a key enzyme for melanin biosynthesis, and hyperpigmentation disorders are associated with abnormal accumulation of melanin pigments, which can be improved by treatment with depigmenting agents. In the present study, piperlonguminine from Piper longum was discovered to inhibit melanin production in melanoma B16 cells stimulated with(More)
Electroporation is widely used to achieve gene transfection. A common problem in electroporation is that it has a lower viability than any other transfection method. In this study, we developed a novel electroporation device using a capillary tip and a pipette that was effective on a wide range of mammalian cells, including cell lines, primary cells, and(More)
Inflammation and thrombogenesis have been suggested as possible causes for cardiovascular events in patients suffering from metabolic syndrome (MS). The primary objective of this study was to determine the relationship between red blood cell (RBC) or white blood cell (WBC) subtypes and MS. The secondary objective was to reveal any gender differences(More)
BACKGROUNDS/AIMS In the treatment of chronic hepatitis B (CHB) with lamivudine, adequate duration of the therapy remains to be determined. In this prospective study, the authors intended to investigate whether long-term additional administration of lamivudine might enhance the durability of lamivudine-induced HBeAg seroconversion. METHODS Eighty-five CHB(More)
Glycyrrhizin is the major active component extracted from licorice (Glycyrrhiza glabra) roots, one of the most widely used herbal preparations for the treatment of liver disorders. This study evaluated the potential beneficial effect of glycyrrhizin in a mouse model of carbon tetrachloride (CCl(4))-induced liver injury. The mice were treated(More)
Focal cortical dysplasia type II (FCDII) is a sporadic developmental malformation of the cerebral cortex characterized by dysmorphic neurons, dyslamination and medically refractory epilepsy. It has been hypothesized that FCD is caused by somatic mutations in affected regions. Here, we used deep whole-exome sequencing (read depth, 412-668×) validated by(More)
BACKGROUND Sorafenib currently sets the new standard for advanced hepatocellular carcinoma (HCC). It has been suggested that Asian patients with HCC have increased susceptibility to hand-foot skin reaction (HFSR) related to sorafenib therapy. The authors investigated the association between sorafenib-induced HFSR and genetic polymorphisms in Korean patients(More)
Alzheimer's disease (AD) is characterized by the accumulation of amyloid plaques and neurofibrillary tangles accompanied by cognitive dysfunction. The aim of the present study was to elucidate preventive and therapeutic potential of stem cells for AD. Among stem cells, autologous human adipose-derived stem cells (hASCs) elicit no immune rejection responses,(More)
