BACKGROUND Neuroendocrine (NE) cells are present in both normal prostate and prostate cancer. In addition, NE differentiation can be induced by various factors, such as IL-6, in vitro and in vivo. However, the mechanism of this differentiation and the role of NE cells in prostate cancer are not well understood. In this study, we evaluated the gene(More)
BACKGROUND Beta-actin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) have been frequently considered as constitutive house keeping genes for RT-PCR and used to normalize changes in specific gene expressions. However, these expressions have been shown to be affected by the sample type and experimental conditions. We investigated which housekeeping gene(More)
PURPOSE Pancreatic cancer still has one of the worst prognoses in gastrointestinal cancers with a 5-year survival rate of 5%, making it necessary to find markers or gene sets that would further classify patients into different risk categories and thus allow more individually adapted multimodality treatment regimens. In this study, we investigated the(More)
The aim of the present study was to examine the efficacy of tumor-targeting Salmonella typhimurium A1-R treatment following anti-vascular endothelial growth factor (VEGF) therapy on VEGF-positive human pancreatic cancer. A pancreatic cancer patient-derived orthotopic xenograft (PDOX) that was VEGF-positive and an orthotopic VEGF-positive human pancreatic(More)
Gemcitabine has been one of the most commonly used agents for pancreatic adenocarcinoma chemotherapy, but the determinants of the sensitivity of and resistance to this agent are not yet fully understood. In this study with pancreatic carcinoma and biliary tract carcinoma cell lines, we examined the gene expression levels of nucleotide transporters and(More)
PURPOSE We studied the risk factors for postoperative mortality between patients who underwent emergency or elective living-donor liver transplantation (LDLT). METHODS Forty-seven patients underwent LDLT in our institute, 16 for emergencies and 31 as elective procedures. The emergency LDLT status was applied to cases in which the time period between(More)
A patient-derived nude-mouse model of soft-tissue sarcoma has been established and treated in the following groups: (1) untreated controls; (2) gemcitabine (GEM) (80 mg/kg, ip, weekly, 3 weeks); (3) Pazopanib (100 mg/kg, orally, daily, 3 weeks) and (4) Salmonella typhimurium A1-R (5 × 10(7) CFU/body, ip, weekly, 3 weeks). The sarcoma was resistant to GEM (p(More)
Glycoprotein nonmetastatic B (GPNMB) is a potential oncogene that is particularly expressed in melanoma and breast cancer (BC). To clarify its clinical significance in BC, we measured serum GPNMB in vivo and investigated its cross talk with human epidermal growth factor 2 (HER2). GPNMB was expressed in four of six breast cell lines (SK-BR-3, BT-474,(More)
HYPOTHESIS Chronic inflammation of esophageal mucosa secondary to refluxed gastric juice increases gene expression of interleukin 8 (IL-8). Antireflux surgery can reduce this overexpression. DESIGN Prospective analysis of archival paraffin-embedded tissue. SETTING Academic tertiary medical center. PATIENTS AND METHODS One hundred eight patients with(More)
5-fluorouracil (5-FU) and oxaliplatin play important roles in chemotherapy for patients with colorectal cancer. The expression levels of thymidylate synthase (TS) and excision repair cross-complementing factor 1 (ERCC1) have been reported to be prognostic markers for patients with 5-FU/oxaliplatin chemotherapy. The aim of this study was to clarify the(More)
