Hypoxia-inducible factor 1 (HIF-1) plays essential roles in tumor angiogenesis and growth by regulating the transcription of several key genes in response to hypoxic stress and growth factors. HIF-1 is a heterodimeric transcriptional activator consisting of inducible alpha and constitutive beta subunits. In oxygenated cells, proteins containing the prolyl(More)
Fourteen cases of inflammatory fibroid polyp of the stomach were studied in terms of immunohistochemistry and ultrastructure. They occurred as polypoid lesions in the antrum, except for two found in the body of the stomach. Out of the 14 cases, two were found to be multiple and the remainder solitary. In all but one lesion, the mucosal layer was involved(More)
Although metastatic colorectal cancer (mCRC) is commonly treated with 5-fluorouracil (5-FU)/leucovorin/oxaliplatin (FOLFOX), their response to FOLFOX varies, and no biomarkers predictive of treatment outcome have been validated. Organic anion transporter 2 (OAT2) and organic cation transporter 2 (OCT2) are critical determinants in uptake of 5-FU and(More)
The role of transcription factor E3 (TFE3), a bHLH transcription factor, in immunology and cancer has been well characterized. Recently, we reported that TFE3 activates hepatic IRS-2 and hexokinase, participates in insulin signaling, and ameliorates diabetes. However, the effects of TFE3 in other organs are poorly understood. Herein, we examined the effects(More)
Transcription factor E3 (TFE3) belongs to a basic helix-loop-helix family, and is involved in the biology of osteoclasts, melanocytes and their malignancies. We previously reported the metabolic effects of TFE3 on insulin in the liver and skeletal muscles in animal models. In the present study, we explored a novel role for TFE3 in a skeletal muscle cell(More)
Organic anion-transporting polypeptide 1A2 (OATP1A2) and organic cation transporter 6 (OCT6) are involved in the uptake of taxanes and anthracyclines, respectively. The aim of this study was to evaluate expression levels of OATP1A2 and OCT6 as a predictor of response to neoadjuvant chemotherapy (NAC) in breast cancer. A total of 124 patients who received(More)
Mitochondrial dysfunction in muscles leads to a wide range of metabolic and age-related disorders. Recently, it has been reported that a natural polyphenol, resveratrol, affects mitochondrial biogenesis. This study aimed to identify other natural polyphenolic compounds that regulate mitochondrial biogenesis in muscles. For this purpose, we used the C2C12(More)
Caffeine enhances endurance performance; however, its effect on accumulated lactate remains unclear. Conversely, taurine, which also enhances endurance performance, decreases accumulated lactate. In this study, the effect of combination of caffeine and taurine on endurance performance was assessed. Mice ran on a treadmill, and the accumulated lactate was(More)
