Our recent study demonstrated that higher expression of N-myc downregulated gene 1 (NDRG1) is closely correlated with poor prognosis in gastric cancer patients. In this study, we asked whether NDRG1 has pivotal roles in malignant progression including metastasis of gastric cancer cells. By gene expression microarray analysis expression of NDRG1 showed the(More)
Gene amplification of HER2/ErbB2 occurs in gastric cancer and the therapeutic efficacy of the HER2-targeted antibody, trastuzumab, has recently been improved against HER2-positive advanced stomach cancer. Here, we examined whether Y-box-binding protein-1 (YB-1) could selectively control HER2 gene expression and cellular sensitivity to EGF receptor (EGFR)(More)
We have recently reported that N-myc downstream-regulated gene 1 (NDRG1)/Ca(2+)-associated protein with a molecular mass of 43kDa (Cap43) suppresses angiogenesis and tumor growth of pancreatic cancer through marked decreases in both the expression of CXC chemokines and phosphorylation of a NF-kappaB signaling molecule, inhibitor of kappaB kinase(More)
Situs inversus totalis is a rare anatomic variant of a complete mirror-image transposition of the thoracic and abdominal viscera. The performance of a pancreaticoduodenectomy and distal pancreatectomy in patients with situs inversus totalis is both rare and challenging. We herein present two cases of pancreatic cancer with situs inversus totalis. The(More)
Many studies have reported methods of cell collection involving percutaneous transhepatic cholangiodrainage (PTCD) and fine-needle aspiration cytology for the diagnosis of gallbladder disease. However, few studies have described the use of a transpapillary approach, i.e., endoscopic transpapillary catheterization into the gallbladder (ETCG). In this study,(More)
The expression of N-myc downstream-regulated gene 1 (NDRG1) was significantly correlated with tumor angiogenesis and malignant progression together with poor prognosis in gastric cancer. However, the underlying mechanism for the role of NDRG1 in the malignant progression of gastric cancer remains unknown. Here we examined whether and how NDRG1 could(More)
The patient was a 67-year-old man under follow-up after gastric cancer surgery. An abdominal CT scan performed 1 year earlier had shown an approximately 14-mm hypovascular mass in the pancreatic body; however, he did not consent to treatment and was followed up for 1 year. A blood workup showed that the fasting blood glucose level, which had been within(More)
PURPOSE We examined whether fluorine-18 fluorodeoxyglucose (FDG) uptake is related to the mammalian target of rapamycin (mTOR) signal pathway and its related proteins in pancreatic cancer patients. METHODS We retrospectively studied 53 pancreatic cancer patients who underwent FDG positron emission tomography (PET) or FDG PET/CT, and complete curative(More)
We have experienced three inverted Meckel’s diverticula with ileus that are diagnosed before surgery and treated with laparoscopic surgery. The patients were 22, 26, and 29 years of age. The history of ileus for each patient differed, being the first experience for one patient, the second for another, and the third experience for the remaining patient. None(More)
