Inosine pranobex-BAN injected intraperitoneally at a daily dose of 500 mg/kg for 15 days into young Sprague-Dawley rats, beginning 24 hours after the implantation of Yoshida ascites tumor cells and the injection of cell-free ascites fluid from the same neoplasia, increased the resistance to the
The effects of inosine on oxipurinol-induced inhibition of 5-fluorouracil (FUra) activation were investigated in a transplantable rat tumor and three normal rat tissues in vitro. FUra activation directed toward RNA was assessed in preparations of small intestine and Jensen sarcoma by determining the
To confirm the effect of nutritional supportive therapy on cancer patients, 52 postoperative gastric cancer patients were selected and given 236 ED as nutritional therapy. Body weight and nutritional index before and after operation, complication, duration in hospital were compared in the
Inosine-5'-phosphate (IMP) dehydrogenase, a regulatory enzyme of guanine nucleotide biosynthesis, may play a role in cell proliferation and malignancy. To assess this role we examined IMP dehydrogenase expression in a series of human solid tumor tissues and tumor cell lines in comparison with their
Inosine 5-monophosphate dehydrogenase II, a key enzyme in the de novo synthesis of purine nucleotides, is expressed in prostate tumors and prostate cancer cells. AVN944 is a new, specific, noncompetitive IMPDH inhibitor. In this study, we investigated the effects of IMPDH inhibitor AVN944 on LNCaP,
Benzamide riboside, a recently discovered inhibitor of IMP dehydrogenase (IMPDH) exhibits oncolytic activity. IMPDH is the key enzyme of de novo guanylate biosynthesis and was shown to be linked with proliferation. Therefore, IMPDH is a very good target for antitumor therapy. In order to be active,
Mycophenolic acid (MPA), an inhibitor of IMP-dehydrogenase (IMPDH), is used worldwide in transplantation. Recently, numerous studies showed its importance in cancer treatment. Consequently, MPA entered clinical trials in advanced multiple myeloma patients. Suberoylanilide hydroxamic acid (SAHA), a
The present study was conducted to evaluate dietary inosine 5'-monophosphate (5'-IMP) on growth, immune genes expression and disease resistance against Aeromonas hydrophila in juvenile gibel carp (Carassius auratus gibelio var. CAS Ⅲ) (initial body weight: 7.48 g). Six diets were formulated
Inosine monophosphate dehydrogenase (IMPDH) controls a key metabolic step in the regulation of cell growth and differentiation. This step is the NAD-dependent oxidation of inosine 5' monophosphate (IMP) to xanthosine 5' monophosphate, the rate-limiting step in the synthesis of the guanine
The relationship between the intracellular concentration of various nucleotides as measured by high-performance liquid chromatography analysis, and the differentiation of 2 human colon cancer cell lines was studied. HT-29 cells were induced to undergo both structural and functional enterocytic
The feasibility of "early" thymidine and inosine protection of methotrexate (MTX) toxicity is evaluated in this paper. This approach is based on the proposition that the most vulnerable period for susceptible host cells to MTX toxicity is an interval following a pulse of MTX when the MTX
Carbocyclic inosine is a potent inhibitor for the growth of the promastigote form of Leishmania tropica and Leishmania donovani. In culture, the EC50 values of carbocyclic inosine are 8.3 X 10(-8) and 1.3 X 10(-7) M for the promastigotes of L. tropica and L. donovani, respectively. On the other
To screen cancer for specific autoantibodies, we applied the approach established by Brichory et al., who reported annexins I and II as specific antigens. Solubilized proteins from a cancer cell line (A549) were separated using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), followed
We have developed an isolated perfused tumor model to study the metabolism of solid tumors by nuclear magnetic resonance spectroscopy. Morris hepatomas (7777) were implanted in the inguinal region of Buffalo rats, such that they developed an isolated blood supply. These tumors were perfused with a
