The cytotoxicity of several antitumor drugs is enhanced by hyperthermia (HT). Using mouse Sarcoma-180 (S-180) tumors, the authors examined the effects of 5-fluorouracil (5-FU) and a combined oral preparation of 1-(2-tetrahydrofuryl)-5-fluorouracil (FT) and uracil in a molar ratio of 1:4 (UFT), in
The use of hyperthermia for the treatment of tumors has been tested in vitro and in vivo experiments as well as clinically for a long time. Combination of hyperthermia with chemotherapy was reported to result in overadditive cytostatic effects. In a clinically adapted, controlled animal experiment,
Herpes simplex virus (HSV) encodes a uracil DNA glycosylase (UNG; UL2), which has been shown to be dispensable for normal replication of HSV-1 in cultured cells (J. Mullaney, H.W. Moss, and D.J. McGeoch, J. Gen. Virol. 70:449-454, 1989). In adult neurons, UNG activity is undetectable (F. Focher, P.
The Yellow Fever (YF) vaccine, an attenuated yellow fever 17D (YF-17D) live vaccine, is one of the most effective and safest vaccines in the world and is regarded as one of the best candidates for viral expression vector. We here first reported in China the construction and characterization of the
A 60-year-old female patient with gastric cancer and lymph node and liver metastases was treated with a combination of tegafur and uracil (UFT) (375 mg/m2/day) and mitomycin C (MMC) (5 mg/m2 once weekly). On day 15, when diarrhea appeared, chemotherapy was stopped immediately. On day 21, the WBC
We report a case of renal cell carcinoma in a 76-year-old man with pulmonary metastasis and tumor thrombus in inferior vena cava. The patient responded to the combination therapy with a small amount of HLBI (human lymphoblastoid interferon-alpha) and UFT (1:4 mixture of tegafur and uracil). HLBI was
Although UFT 300 mg/m2/day and leucovorin 90 mg/day administered orally in divided doses administered every 8 hours for 28 days repeated every 35 days could be administered safely to patients with advanced hepatomas and good performance status, this combination and schedule has limited activity in
The effectiveness of 5-fluorouracil (5-FU), FT-207 and FT-207 + uracil in combination with two repetitions of 43 degrees C hyperthermia in the treatment of the Meth-A-Fibrosarcoma and Sarcoma-180 was examined in vivo in BALB/c mice. The antitumor effect was evaluated in terms of inhibition of tumor
Recently, analysis of tumor antigens using micro-arrays has revealed upregulation of cancer-testis antigens RNF43 and TOMM34 and vascular endothelial growth factor receptors VEGFR1 and VEGFR2 in colorectal cancer. A phase I clinical trial of peptide vaccine therapy together with oral anticancer
Rigid amphipathic fusion inhibitors (RAFIs) are a family of nucleoside derivatives that inhibit the infectivity of several enveloped viruses by interacting with virion envelope lipids and inhibiting fusion between viral and cellular membranes. Here we tested the antiviral activity of two RAFIs,
Eight different compounds, all nucleoside analogues, could presently be considered as potential drug candidates for the treatment of Ebola virus (EBOV) and/or other hemorrhagic fever virus (HFV) infections. They can be considered as either (i) adenine analogues (3-deazaneplanocin A, galidesivir,
Magnetic hyperthermia, or the heating of tissues using magnetic materials, is a promising approach for treating cancer. We found that human mesenchymal stem cells (MSCs) isolated from various tissues and MSCs expressing the yeast cytosine deaminase∷uracil phosphoribosyl transferase suicide fusion
The patient was a 55-year-old man who complained of lower abdominal pain and fever, and was admitted to an emergency clinic. His diagnosis was rectal perforation combined with intraperitoneal abscess. Because his condition was in the preseptic state, an emergency operation was performed for
TG4023 is a modified vaccinia virus Ankara (MVA) containing the yeast-originated transgene FCU1, expressing cytosine deaminase and uracil phosphoribosyltransferase enzymes that transform the prodrug flucytosine (5-FC) into cytotoxic 5-fluorouracil (5-FU) and 5-fluorouridine-5′-monophosphate,
A clinical and pharmacokinetic investigation of prolonged administration of high-dose uridine was performed in seven patients with advanced-stage cancer. Uridine administration was examined as a continuous infusion at 1 and 2.5 g/m2/hr (two patients) and as a series of intermittent infusions during
