DNA Damage and Polyploidization
2010A growing body of evidence indicates that polyploidization triggers chromosomal instability and contributes to tumorigenesis. DNA damage is increasingly being recognized for its roles in promoting polyploidization. Although elegant mechanisms known as the DNA damage checkpoints are responsible for halting the cell cycle after DNA damage, agents that ...

DNA strand breaks are potentially mutagenic and must, therefore, be recognized and repaired. Recent work has identified DNA polymerase epsilon, Ku, and proteins such as DNA-PKcs, Mec1 and Tel1 as key players in DNA damage recognition pathways. Studies on these and other factors have provided important insights into the mechanisms of DNA repair and how ...

Carotenoids are among the best known antioxidant phytochemicals, and are widely believed to contribute to the health-promoting properties of fruits and vegetables. Investigations of the effects of carotenoids have been carried out at different levels: in cultured cells, in experimental animals, and in humans.

Sperm DNA damage and its relation with leukocyte DNA damage
Reproductive Toxicology, 2010DNA fragmentation in human sperm has been related to endogenous and exogenous factors. Exogenous factors can also affect leukocyte DNA integrity. This study evaluated the relation between sperm DNA damage and leukocyte DNA integrity, as a predictor of exogenous factors.

DNA damage, repair and chromosomal damage
International Journal of Radiation Biology, 1997An important question in radiobiology is the relationship between primary DNA damage and chromosomal aberrations. What determines the chromosomal aberration frequency, especially in radiosensitive cells? Much evidence points to the double-strand break (dsb) as the critical lesion, however there is controversy over whether it is the initial induction ...

Some of the background to radiation chemical studies of DNA damage is presented, followed by a review of measurements of such damage and its repair in mammalian cells. While most effort has been placed on the measurement of radiation-induced strand breaks (because assays can be used in the biologically relevant dose range), the radiation-altered bases ...

Abstract DNA-damaging agents have represented the first effective treatment for the blood cancer multiple myeloma, and after 65 years since their introduction to the clinic, they remain one of the mainstay therapies for this disease. Myeloma is a cancer of plasma cells.
