T-2 mycotoxin, a natural contaminant of cereals and agricultural products, is known to exhibit the severest toxicity and the lowest LD50 value among trichothecenes. Since quercetin has been reported to have strong antioxidant properties, the effect of quercetin and T-2 toxin on rabbit ovarian cell proliferation and apoptosis was assessed. In the ovaries, proliferating cells were analysed immunocytochemically...
Research into potential anticancer agents has shown that 2-methoxyestradiol exerts antiproliferative activity in vitro and in vivo in an estrogen receptor-independent manner. Due to its limited biological accessibility and rapid metabolic degradation, several new analogues have been developed in recent years. This study investigated the in vitro effects of a novel in silicodesigned compound (C16)...
Using the whole-cell patch-clamp technique, we investigated the influence of 8-prenylnaringenin on the activity of the voltage-gated Kv1.3 potassium channels in the human leukemic T lymphocyte cell line Jurkat. 8-prenylnaringenin is a potent plant-derived phytoestrogen that has been found to inhibit cancer cell proliferation. The results show that it inhibited the Kv1.3 channels in a concentration-dependent...
Ciprofloxacin is widely used in antimicrobial therapy. However it also inhibits mitochondrial topoisomerase II and therefore affects cellular energy metabolism. At a concentration exceeding 80 µg/ml ciprofloxacin induces apoptosis, while at 25 µg/ml it inhibits proliferation of Jurkat cells without any symptoms of cell death. The aim of this study was to explain the mechanisms of ciprofloxacin-evoked...
Aim of study was to verify whether pulsating electromagnetic field (PEMF) can affect cancer cells proliferation and death. U937 human lymphoid cell line at densities starting from 1x106 cells/ml to 0.0625x106 cells/ml, were exposed to a pulsating magnetic field 50Hz, 45±5 mT three times for 3 h per each stimulation with 24 h intervals. Proliferation has been studied by counting number of cells stimulated...
