Increasing DNA repair methyltransferase levels via bone marrow stem cell transduction rescues mice from the toxic effects of 1,3-bis(2-chloroethyl)-1-nitrosourea, a chemotherapeutic alkylating agent.

Abstract excerpt

The chloroethylnitrosourea (CNU) alkylating agents are commonly used for cancer chemotherapy, but their usefulness is limited by severe bone marrow toxicity that causes the cumulative depletion of all hematopoietic lineages (pancytopenia). Bone marrow CNU sensitivity is probably due to the inefficient repair of CNU-induced DNA damage; relative to other tissues, bone marrow cells express extremely low levels of...
