Arsenic trioxide (As2O3; ATO, TRISENOX®) is used to treat patients with refractory or relapsed acute promyelocytic leukaemia while its application for treatment of solid cancers like glioblastoma is still under evaluation. In the present study, we investigated the interaction of arsenic trioxide with metallothionein (MT) isoforms as a possible (protective(More)
The accumulation of cadmium, its affinity for metallothioneins (MTs), and its relation to copper, zinc, and selenium were investigated in the experimental mudpuppy Necturus maculosus and the common toad Bufo bufo captured in nature. Specimens of N. maculosus were exposed to waterborne Cd (85 μg/L) for up to 40 days. Exposure resulted in tissue-dependent(More)
Various biomarkers were used to assess selenium (Se) status during 3 months of basic military training in a group of recruits. Samples of whole blood and plasma or serum were taken from a group of conscripts three times: at the beginning (n = 15), in the middle immediately after a severely stressful physical activity (n = 15) and at the end of military(More)
The action of mercuric chloride and methyl mercuric chloride on the membrane lateral domain organization of bovine, equine, and canine erythrocytes was studied. Electron paramagnetic resonance (EPR) spectra of spin-labeled erythrocytes were analyzed with respect to their lateral domain structure. Continuous alteration of the membrane domain populations(More)
Arsenic trioxide (As(III) in solution) has been shown to be the most active single agent in combating acute promyelocytic leukemia (APL). It is metabolized and excreted via urine as monomethylarsonic acid (MMA), dimethylarsinic acid (DMA) and As(V), along with excess As(III). In our study eight APL patients were treated (intravenously) with 0.15 mg(More)
The difference in arsenic concentration and speciation between benthic (Pteromylaeus bovinus, Myliobatis aquila) and pelagic rays (Pteroplatytrygon violacea) from the northern Adriatic Sea (Gulf of Trieste) in relation to their size (age) was investigated. High arsenic concentrations were found in both groups with tendency of more efficient arsenic(More)
The ability of As2O3 to induce apoptosis in various malignant cell lines has made it a potential treatment agent for several malignancies. In this study the chemical stability of As2O3 (As(III)) in cell-free growth media with various compositions was studied (MEM with different amount of amino acids and DMEM). Special attention was given to evaluate the(More)
This work presents an analytical chemist’s view on the sometimes unconscious use of arsenic trioxide in (bio)medical research. Arsenic trioxide is a frequently used chemical in cancer treatment research and its action to various malignant cells has been extensively studied and published. Unfortunately some research articles show trivial errors with regards(More)
The binding of mercury (Hg) to metallothioneins (MTs) and the relation between Hg and selenium in supernatants of hepatopancreas and gill tissues of the common mussel Mytilus galloprovincialis (Lamarck, 1819) was investigated. The mussels were exposed to different Hg concentrations in laboratory conditions: 2.5 microgHg/L, 4 d exposure (short term) and 60(More)
