Aberrant DNA damage response and DNA repair pathway in high glucose conditions.

In high glucose conditions, defective DNA damage responses most likely contribute to the higher mutation rate in renal epithelial cells, in addition to oxidative DNA damage. The DNA damage and repair are normal enzyme dependent mechanisms requiring euglycemic environments. Aberrant DNA damage response and repair in cells grown in high glucose conditions underscore the importance of maintaining good glycemic control in patients with diabetes mellitus and cancer.
