The purpose of the study was to compare cytotoxicity two Quillaja saponaria bark saponin (QBS) mixtures against lung cell lines: normal MRC-5 fibroblast line and tumor A-549 epithelial cells lungs’ alveoli. study, performed both at a macro-scale in dedicated microfluidic device, showed that QBS more toxic abundant cholesterol (MRC-5). mixture with higher fraction found be cytotoxic towards line...
objective: verotoxin is a member of shiga toxin family. this family contains ab protein toxins with an enzymatic (a) and a binding (b) compartment. cells that have receptor (gb3) are sensitive to cytotoxic effects of toxin. it has been shown that various tumor cells have gb3 receptor and are selectively sensitive to apoptotic effect of verotoxin. studies on tumor cell lines and laboratory anima...
objective: today, special attention is paid to the use of zirconium dioxide nanoparticle (nano-zro2), a neutral bioceramic metal, particularly for drug and gene delivery in medicine. however, there are some reports implying that use of nano-zro2 is associated with cytotoxic effects like inhibiting the cell proliferation, dna damage and apoptosis. in the present study, we examined whether nano-z...
WQ-3034 is a newly synthesized acidic fluoroquinolone. We assessed its in vitro activity against Mycobacterium tuberculosis and M. avium complex using levofloxacin (LVFX), ciprofloxacin (CPFX), sparfloxacin (SPFX), and KRM-1648 (KRM) as reference drugs. The MICs of these agents were determined by the agar dilution method with 7H11 medium. The MICs at which 50 and 90% of the test strains were in...
objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...
background: erythropoietin (epo) is a glycoprotein hormone function to regulate the production of red blood cells. deficiency of epo is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. availability of recombinant epo has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. glycosylation of e...
The non-receptor tyrosine kinase ABL drives myeloid progenitor expansion in human chronic myeloid leukemia. ABL inhibition by the tyrosine kinase inhibitor nilotinib is a first-line treatment for this disease. Recently, ABL has also been implicated in the transforming properties of solid tumors, including triple negative (TN) breast cancer. TN breast cancers are highly metastatic and several ce...
BACKGROUND Human DNA topoisomerase I (topo 1) is an essential nuclear enzyme involved in vital cellular processes and the sole target of antitumor drugs of the camptothecin (CPT) family. The CPT derivative topotecan (Tpt, Hycamtin) is currently used in clinic, its effectiveness varying considerably for different types of cancer. The purpose of this study was to compare time- and dose-dependent ...
the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...
