Molecular pathways involved in cell death after chemically induced DNA damage.

Abstract

DNA damage is at the center of the genesis, progression and treatment of cancer. We review here the molecular mechanisms of the DNA damage inducing small molecules most commonly used in cancer therapy. Cell cycle control and DNA repair mechanisms are known to be activated after DNA damage. Here, we revise recent discoveries related to the cell cycle control and DNA repair processes and how these findings are being utilized for the more efficient, powerful and selective therapies for cancer treatment.
