Analysis of chromatin integrity and DNA damage of buffalo spermatozoa
This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...
متن کاملChromatin modulation and the DNA damage response.
The ability to sense and respond appropriately to genetic lesions is vitally important to maintain the integrity of the genome. Emerging evidence indicates that various modulations to chromatin structure are centrally important to many aspects of the DNA damage response (DDR). Here, we discuss recently described roles for specific post-translational covalent modifications to histone proteins, a...

متن کاملChromatin Compaction Protects Genomic DNA from Radiation Damage
Genomic DNA is organized three-dimensionally in the nucleus, and is thought to form compact chromatin domains. Although chromatin compaction is known to be essential for mitosis, whether it confers other advantages, particularly in interphase cells, remains unknown. Here, we report that chromatin compaction protects genomic DNA from radiation damage. Using a newly developed solid-phase system, ...
متن کاملChromatin Remodeling, DNA Damage Repair and Aging
Cells are constantly exposed to a variety of environmental and endogenous conditions causing DNA damage, which is detected and repaired by conserved DNA repair pathways to maintain genomic integrity. Chromatin remodeling is critical in this process, as the organization of eukaryotic DNA into compact chromatin presents a natural barrier to all DNA-related events. Studies on human premature aging...
