AIMS Whether gemcitabine based chemoradiotherapy (GEM-based CRT) is superior to 5-fluorouracil based chemoradiotherapy (5-FU-based CRT) for locally advanced pancreatic cancer (LAPC) remains uncertain. The aim of the present study was to evaluate the effect of GEM-based CRT compared with 5-FU-based CRT. METHODS Electronic database including Medline, Embase, Cochrane controlled trials register,...

A series of observations have indicated that tau, one of the major microtubule-associated proteins, is involved in neuronal cell morphogenesis and axonal maintenance. Tau is also the major component of paired helical filaments found in brains affected by Alzheimer's disease. To explore an as yet unidentified role of tau in vivo, approximately 11,000 mRNAs were profiled from tau-deficient mouse ...

PURPOSE Radiation and chemotherapy are the most common course of treatment for B-cell lymphoma. Doxorubicin (DOX), gemcitabine (GEM), and vincristine (VCR) are the commonly used antilymphoma chemotherapeutic drugs. The aim of this study is to construct a novel drug delivery system for the combination delivery of the three drugs on lymphoma. MATERIALS AND METHODS DOX-GEM prodrug was synthesize...

Histone deacetylase inhibitors (HDACis) have been developed as a new type of drug for cancer treatment. In this study, we examine the augmentation efficacy of depsipeptide (FK228) in combination with gemcitabine (GEM) or docetaxel (DOC) in vitro and in vivo against hormone refractory prostate cancer (HRPC). The anti-proliferative effects, cell cycle distribution and apoptotic status were assess...

The BRCA/Fanconi anemia (FA) pathway plays a key role in the repair of DNA double strand breaks. We focused on this pathway to clarify chemoresistance mechanisms in biliary tract cancer (BTC). We also investigated changes in the CD24(+)/44(+) population that may be involved in chemoresistance, as this population likely includes cancer stem cells. We used three BTC cell lines to establish gemcit...

Oxidative stress induction is a common effector pathway for commonly used chemotherapeutic agents like gemcitabine (GEM) in hepatocellular carcinoma (HCC) patients. However, GEM alone or in combination with oxiplatin hardly renders any survival benefits to HCC patients. Mitochondrial uncoupling protein 2 (UCP2) is known to suppress mitochondrial reactive oxygen species (ROS) generation, thus mi...

The prognosis of pancreatic cancer remains poor, and the standard first-line chemotherapy with gemcitabine (GEM) has a response rate of less than 20%. Since expression of deoxycytidine kinase (dCK) seems important for improvement of GEM sensitivity, overexpression of dCK was investigated using pancreatic cancer cell lines (Panc-1, MIAPaCa-2 and BxPC-3). dCK gene was introduced into the cell lin...

The main theoretical aspects of gravitoelectromagnetism (“GEM”) are presented. Two basic approaches to this subject are described and the role of the gravitational Larmor theorem is emphasized. Some of the consequences of GEM are briefly mentioned.
