Název v původním jazyce
Subcellular Localization of Proteins Responding to Mitoxantrone-Induced DNA Damage in Leukaemic Cells
Popis výsledku v původním jazyce
The aim of the present study was to investigate the subcellular localization of proteins participating in the double-strand break response pathway - p53, Mdm2, p21 and Chk2. MOLT-4 cells were pre-treated with mitoxantrone in concentrations 1 nmo1/1 and 5nmo1/1. The trypan blue technique was used to determine cell viability and proliferation. Western blotting was used to evaluate changes in p53, Mdm2 and Chk2 protein expression and sandwich ELISA was used to evaluate changes in the p21 protein amount. After 1 nmo1/1 mitoxantrone cells did not die, but their ability to proliferate was decreased. The p53 protein was activated and phosphorylated at serines 15 and 392 and accumulated in the nucleus after 24 and 48 h. The Mdm2 protein was present in the cytoplasm with its maximal level after 8 and 16 h. The p21 protein was detected in the nucleus after 24 and 48 h. Increased levels of phosphorylated Chk2 at threonine 68 were observed in the cytoplasmic fraction after 24 and 48 h of mitoxant
