In addition, these measurements, particularly if they reflect long-term exposure to carcinogens could re

Two major pathways for the repair of alkylation damage have been identified. The removal of O.-methylguanine (O.-meG) adducts proceeds . the transfer of the alkyl group to a cysteine residu

We therefore initiated a study of the O. methylguanine DNA methyltransferase (MT) activity in normal controls and in patients with HD, ANLL . or t-ANLL. As part of

Some of them are repaired by alkyl DNA transferase while others are repaired by DNA glycosylases which generate as products the free alkylated base and an apurinic site (AP-site). This is a secondary lesion which is harmful to the cell and is actively repaired. Alkylation

Alan A. D. Peatfield,Christine Morrists. Misreplication or misrepair of DNA adducts can lead to mutations, which in turn can act as the genetic precursors of cancer and other genetic diseases. A problem in contemporary cancer biology has been to discern the mechanisms by which DNA adducts lead to mutations. This problem is complicated

Although repair has been studied extensively in procaryotic and eucaryotic cells—including human cells in culture—there are important differences between repair by human skin cells in culture and huma
