Mitotic cell death by chromosome fragmentation.
Cell death plays a key role for both cancer progression and treatment. In this report, we characterize chromosome fragmentation, a new type of cell death that takes place during metaphase where condensed chromosomes are progressively degraded. It occurs spontaneously without any treatment in instances such as inherited status of genomic instability, or it can be induced by treatment with chemot...
متن کاملBiological Dose Assessment by Chemical Induction of Premature Chromosome Condensation
Dose assessment of radiation victims is a key element in medical management of radiation accidents. At high radiation doses (> 6 Gy), dicentric assay lose its efficiency and premature chromosome condensation (PCC) assay was proposed to overcome the restrictions of dicentric assay. It was shown that PCC ring is more suitable and simpler than dicentric for biodosimetry in high radiation doses. In...
متن کاملConstruction of a dose – response curve by induction of premature chromosome condensation for biological dosimetry
Premature Chromosome Condensation (PCC) appears to have a possible utility for biological dosimetry purposes. The PCC technique may be adapted for cases of suspicion of overexposure where sampling is performed at least one day after an accident. For this purpose, human blood samples were exposed in vitro to 60Co up to 10 Gy and the PCC technique was performed immediately after irradiation. Anal...
متن کاملDomain during Mitotic Chromosome Condensation
The NH 2 -terminal domain (N-tail) of histone H3 has been implicated in chromatin compaction and its phosphorylation at Ser10 is tightly correlated with mitotic chromosome condensation. We have developed one mAb that specifically recognizes histone H3 N-tails phosphorylated at Ser10 (H3P Ab) and another that recognizes phosphorylated and unphosphorylated H3 N-tails equally well (H3 Ab). Immunoc...
متن کاملInduction of premature chromosome condensation (PCC) by calyculin A for biodosimetry
Background: Premature chromosome condensation (PCC) is a method for interphase chromosome analysis in biodosimetry. This study was performed to verify the usefulness of PCC induced by calyculin A in human peripheral blood lymphocytes (pbl) for biological dosimetry and possible construction of dose-response curve. Materials and Methods: Peripheral blood was obtained from a healthy donor and expo...
