A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

Previous studies have largely focused on how ionizing radiation affects DNA organization, showing that damage can reorganize chromatin structure and impact DNA repair efficiency. However ...

The team’s model predicted that approximately 103,000 cancers per year – around 5 percent of the 2 million new cancer ...

This takes place inside the circular structure of the scanner ... prolonged or repeated exposure to ionizing radiation can cause DNA damage that may increase the risk of uncontrolled cell growth ...

Nuclear waste is one of the deadliest materials on earth, containing radioactive materials that emit ionising radiation which can cause severe damage to living tissues and DNA and increase the ...

And there is shown the potential to be used prophylactically as a means to prevent radiation damage rather ... to toxic doses of ionizing radiation. Radiation disrupts the DNA, destroys rapidly ...

Abstract: Ionizing radiation induces clusters of DNA damages - oxidized bases ... that low doses of low and high linear energy transfer (LET) radiation induce such damage clusters in human cells. In ...

Abstract: To determine the patterns of gene expression responsible for the radiosensitivity of glioblastoma cells, we analyzed transcriptional changes after ionizing radiation in ... of major pathways ...
