OBJECTIVES In this study, we demonstrated that TBEV-infected ticks have been distributed in the ROK, combined with our previous results. These results suggest that TBEV may exist in the ROK, and H. longicornis, H. flava, and I. nipponensis may be potential vectors of TBEV. In addition, these results emphasize the need for further epidemiological research of(More)
DJ-1 is linked to an early-onset autosomal recessive Parkinson's disease (PD) characterized primarily by selective loss of dopaminergic (DA) neurons, which results in motor disturbances. However, our understanding on how mutations in DJ-1 are related to PD is unclear. Here, we isolated the DJ-1 orthologue, DJ-1beta, in Drosophila and characterized its(More)
The cerebral deposition of amyloid beta-peptide (Abeta) is a major factor in the etiology of Alzheimer's disease. beta-Secretase (BACE) initiates the generation of Abeta by cleaving the amyloid precursor protein at the beta-site and is therefore a prime target for therapeutic intervention. Here we report a cell-based method suitable for monitoring BACE(More)
We report here a genetic assay suitable for detecting site-specific proteolysis in secretory pathways. The yeast enzyme invertase is linked to the truncated lumenal region of the yeast Golgi membrane protein STE13 via a protease substrate domain in a Saccharomyces cerevisiae strain lacking invertase. When the substrate is cleaved by a specific protease, the(More)
In Drosophila melanogaster, specification of wing vein cells and sensory organ precursor (SOP) cells, which later give rise to a bristle, requires EGFR signaling. Here, we show that Pumilio (Pum), an RNA-binding translational repressor, negatively regulates EGFR signaling in wing vein and bristle development. We observed that loss of Pum function yielded(More)
Identifying cellular substrates repertoire of individual proteases will facilitate our understanding of their physiological and pathological roles. In this article, we employed a yeast-based screening method to isolate CED-3 substrates. This method uses a transcription factor anchored to the plasma membrane by fusion to a library of cellular protein(More)
OBJECTIVES Measurements of stroke volume variation for volume management in mechanically ventilated patients are influenced by various factors, such as tidal volume, respiratory rate, and chest/lung compliance. However, research regarding the effect of positive end-expiratory pressure on stroke volume variation is limited. METHODS Patients were divided(More)
Phellodendri Cortex (PC) is a traditional herbal medicine, widely used in Korea and China. The effects of the methanol extract of Phellodendri Cortex (PC extract) on 1-methyl-4-phenylpyridinium (MPP(+))-induced neuronal apoptosis in PC-12 cells have been investigated. MPP(+)-induced apoptosis in PC-12 cells was accompanied by an increased bax/bcl-2 ratio,(More)
