The study by Greve and colleagues, in this issue of Cancer Research, provides new molecular insights into the intriguing clinical activity DNA hypomethylating agents (HMA) patients with acute myeloid leukemia (AML) monosomal karyotypes. Patients AML adverse karyotypes are known to benefit from HMAs, but not cytarabine, a cytidine analog without HMA activity, specific mechanisms remain poorly un...
Tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide, NSC 286193), a selective inhibitor of the activity of IMP dehydrogenase (EC 1.1.1.205), the rate-limiting enzyme of de novo GTP biosynthesis, provided in end stage leukemic patients a rapid decrease of IMP dehydrogenase activity and GTP concentration in the blast cells and a subsequent decline in blast cell count. Sixteen consecutive pat...
BACKGROUND Recent studies show the importance of interactions between CD47 expressed on acute myeloid leukemia (AML) cells and the inhibitory immunoreceptor, signal regulatory protein-alpha (SIRPα) on macrophages. Although AML cells express SIRPα, its function has not been investigated in these cells. In this study we aimed to determine the role of the SIRPα in acute myeloid leukemia. DESIGN ...
Fifty-seven patients with refractory acute leukemia were treated with high-dose cytosine arabinoside to establish the maximum tolerated dose and duration and to determine the antileukemic activity. The maximum tolerated regimen was found to be 3 g/sq m every 12 hr for 6 days. At this dose, nonhematologic toxicity was limited to conjunctivitis in approximately half of the patients, and liver tox...
Currently no therapy of acute lymphoblastic leukemia is conceivable without L-asparaginase drugs, with its antileukemic effect by extracellular asparagine depletion, thus preventing admission to leukemic cell. Besides high antitumor effect, drugs have side and toxic effects, such as hypersensitivity reactions, thrombosis, pancreatitis / pancreatic necrosis, hepatotoxicity. For safety profile im...
Phytochemical studies are seeking new alternatives to prevent or treat cancer, including different types of leukemias. Campomanesia adamantium, commonly known as guavira or guabiroba, exhibits pharmacological properties including antioxidant, antimicrobial, and antiproliferative activities. Considering the anticancer potential of this plant species, the aim of this study was to evaluate the ant...
