Mitochondrial trifunctional protein (TP), an enzyme of beta-oxidation, is a multienzyme complex composed of four molecules of the alpha-subunit (HADHA) containing the enoyl-CoA hydratase and 3-hydroxyacyl-CoA dehydrogenase domains and four molecules of the beta-subunit (HADHB) containing the 3-ketoacyl-CoA thiolase domain. An inborn error of this enzyme(More)
We report 3 patients who experienced nonconvulsive status epilepticus following generalized convulsions during antidepressant treatment. All showed prolonged confusion with some psychiatric symptoms, and their electroencephalograms (EEGs) showed either bilateral synchronous multiple spike wave discharges or continuous diffuse sharp and slow waves. When(More)
Identification of regulatory elements within the genome is crucial for understanding the mechanisms that govern cell type-specific gene expression. We generated genome-wide maps of open chromatin sites in 3T3-L1 adipocytes (on day 0 and day 8 of differentiation) and NIH-3T3 fibroblasts using formaldehyde-assisted isolation of regulatory elements coupled(More)
In order to clarify the expression of cytochrome P450 and glutathione S-transferase in human esophagus, 41 samples of human esophagus with squamous-cell carcinoma were investigated by immunoblot analysis and enzyme assays. Cytochrome P450 1A2/1 was clearly expressed in microsomes, and the amount in samples with tumorous tissue was significantly greater than(More)
BACKGROUND Inhibitors of the epidermal growth factor (EGFR) signaling pathway have a major role in the treatment of KRAS wild-type colorectal cancer patients. The EGFR pathway has been shown to be activated in gastric cancer (GC). However, published data on KRAS and BRAF mutation status is limited in GC and has not been compared between GC from different(More)
BACKGROUND X-chromosome-linked inhibitor of apoptosis (XIAP) is one of the anti-apoptotic proteins leading to chemoresistance in several cancers. The aim of this study is to evaluate the impact of XIAP expression upon ovarian clear cell carcinoma (CCC) that has a platinum-resistant phenotype. METHODS Tissue microarrays made from 90 CCC patients were(More)
BACKGROUND High-temperature-required protein A2 (HtrA2), a protein relating with apoptosis in a caspases-dependent and non-dependent manner, has been reported to be associated with chemosensitivity in several human cancers. METHODS Tissue microarrays made from 142 patients with high-grade serous ovarian adenocarcinoma were evaluated to assess whether(More)
