Genetic modifiers of carcinogen DNA adducts in target lung and peripheral blood mononuclear cells.

abstract：:Chemotherapeutic agents have been the mainstay of cancer therapy for years. However, their effectiveness has been limited by toxicities they impart on normal cells. Staurosporine (ST) has been shown to arrest normal, but not breast cancer, cells in G1. Therefore, ST may become a chemoprotective agent, arresting normal...
