The aim of the study was an evaluation of changes in protein level and activity of SOD isoenzymes, and the participation of AP-1 and NF-κB in subsequent stages of colorectal cancer development. Studies were conducted on 65 colorectal cancers. Controls were unchanged colon regions. Activity of SOD isoenzymes, lipid peroxidation level (TBARS), and protein level of SOD1, SOD2, AP-1 and NF-κB were determined...
Looking for a mechanism of induction of chromosomal aberrations by thiram we checked its ability to damage bacterial DNA. Evaluation of the mutagenic effect of thiram was by: (i) the Salmonella!mammalian microsome Ames test with S. typhimurium TA102 strain, (ii) E. coli PQ37 strain to reveal an induction of the SOS response, (iii) test with E. coli BH20 fpg- and BH190 fpg-uvrA- mutants to check possible...
