The three-dimensional molecular models of DNA triple helices and triple-stranded brain-like structure were built up by molecular architecture, and their structural features and energy decomposition were examined. The results showed: (i) The base trip

We have measured the abilities of extracts of tissues from human breast tumors to demethylate adducts of O6-meG in exogenous DNA by transfer of the methyl group to an acceptor protein. The results have shown that all 21 specimens examined (including

Extracts of peripheral lymphocytes from six individuals with chronic lymphocytic leukemia (CLL) were assayed for the ability to remove O6-methylguanine (O6MeGua) from exogenous DNA. The O6MeGua-removing activity in CLL lymphocytes, predominantly B ce

The biological effects of DNA adducts depend on their nature, and on their half-lives relative to the rates of DNA replication and transcription. Their half-lives are determined by the rates of spontaneous decay, such as depurination, and the rates o
