This study investigated the anticancer effects of N-farnesyloxy-norcantharimide (NOC15), a newly synthesized norcantharidin (NCTD) analogue, on human leukemic Jurkat T cells and the signaling pathway underlying its effects. We found that the half maximal inhibitory concentration (IC50) of NOC15 on Jurkat T cells is 1.4 μmol/l, which is 11.14-fold (=15.6÷1.4) smaller than the 15.6 μmol/l of NCTD...

Mean plasma hypoxanthine (Hyp) concentrations determined by high-pressure liquid chromatography were 0.56 MM (range, 0.2 to 1.9 MM)in 16 normal subjects, 0.68 MM(range, 0.1 to 1.1 MM)in 10 untreated acute leukemic subjects, and 0.89 MM(range, 0.3 to 2.6 MM)in 14 solid tumor patients. Despite large differences in Hyp concentration between patients, every 4-hr sampling, indicated that diurnal var...

background: acute myeloid leukemia (aml) is an immunophenotypically heterogeneous malignant disease, in which cd34 positivity is associated with poor prognosis. osteopontin (opn) plays different roles in physiologic and pathologic conditions like: survival, metastasis and cell protection from cytotoxic and apoptotic stimuli. due to anti-apoptotic effect of opn in normal and malignant cells, sil...

BACKGROUND Endoplasmic reticulum (ER) calcium storage and release play important roles in B lymphocyte maturation, survival, antigen-dependent cell activation and immunoglobulin synthesis. Calcium is accumulated in the endoplasmic reticulum (ER) by Sarco/Endoplasmic Reticulum Calcium ATPases (SERCA enzymes). Because lymphocyte function is critically dependent on SERCA activity, it is important ...

By Jo WRIGHT GOODMAN AND GEORGE S. HoixSoN T HE QUESTION of stem cells in peripheral blood is as old as histology itself, for the description of the hemocytoblast is equivalant in most accounts to that of the large lymphocyte or lymphoblast. Despite the fact that large lymphocytes and, at least in some species, occasional lymphoblasts are found normally in the peripheral circulation, the presen...

Zero gravity causes several changes in metabolic and functional aspects of the human body and experiments in space flight have demonstrated alterations in cancer growth and progression. This study reports the genome wide expression profiling of a colorectal cancer cell line-DLD-1, and a lymphoblast leukemic cell line-MOLT-4, under simulated microgravity in an effort to understand central proces...
