“An increase of the intracellular reactive oxygen species (ROS) concentration leads to the development of oxidative stress and, thus, to the damage of cell components. The cause-and-effect relations between these processes have not been fully established yet.\n\nThe ability of photo excited supramolecular composites containing fullerenes C-60 immobilized at LEE011 mw nanosilica particles to generate reactive oxygen species (ROS) in cells of two types (rat thymocytes, and transformed cells of ascite Erlich carcinoma, EAC, and leucosis L1210) is demonstrated.\n\nThe damaging effect of photo

excited C-60-composites are shown, which appeared to be selective and manifested in transformed cells, but not in thymocytes. It has been shown that after the irradiation of aqueous solutions or cell suspensions in the presence of fullerene C-60, the generation of reactive oxygen species is observed. It has been shown that the influence of photo excited fullerene C-60 on metabolic processes depends on the composition Of C-60-containing complex and on the type of the cells. The damaging effects of photo excited fullerene C-60-containing composites were demonstrated to be selective. The

data presented suggest that the application JNK-IN-8 mouse of fullerene C-60-containing composites for the selective activation of ROS-dependent death program in certain types of tumor cells is very promising.”
“OBJECTIVE\n\nTo determine whether the cumulative effects

of five prostate cancer risk alleles (three single-nucleotide polymorphisms [SNPs] on chromosome 8Q24 and two SNPs on chromosome 17a) could help to identify possibly ‘insignificant’ disease.\n\nMATERIALS AND METHODS\n\nWe genotyped 629 men of European ancestry who underwent radical prostatectomy KU-57788 datasheet at our institution between 2002 and 2007. Possibly ‘insignificant’ CaP was defined using the Ohori criteria (organ-confined, tumour volume < 0.5 mL, Gleason pattern < 4). Statistical analysis was used to compare patients with ‘insignificant’ and all other ‘significant’ cancer based upon genotype. Carrier status for the 5 SNPs were compared between patients with ‘insignificant’ disease and a separate population of 801 controls without CaP.\n\nRESULTS\n\nOverall, 38 (6.0%) patients with CaP met the Ohori criteria for ‘insignificant’ disease. Men with ‘significant’ cancer had a greater frequency of any of the five risk alleles than either patients with ‘insignificant’ disease or controls. None of the individual alleles genotyped on chromosomes 8 or 17 distinguished between ‘significant’ and ‘insignificant’ CaP. However, carriers of two or more risk alleles were more likely to have ‘significant’ disease.\n\nCONCLUSIONS\n\nAlthough no single risk allele distinguished ‘insignificant’ CaP, ‘insignificant’ disease was nearly three times as likely among carriers of < one risk allele.
