WebbInhibition by nitric oxide of the repair protein, O6-methylguanine-DNA-methyltransferase Nitric oxide (NO) has been shown to be involved in a number of physiological processes. WebbCytoxicity of alkylating chemotherapeutic drugs is affected by the cellular content of the enzyme O6-methylguanine-DNA methyl transferase (MGMT). Since high levels of the enzyme confer the efficient repair of DNA alkylation, the chemotherapeutic potential of alkylating chemicals can be maintained either increasing drug dosage or reducing the … motorcycles for sale on craigslist in nc

Webb2 juni 2015 · Treatment of the cells with TMZ, BCNU or MEL in combination with O6‑benzylguanine, an MGMT inhibitor, was demonstrated to sensitize the two cell lines to these agents. However, the extent of sensitization was not found to be correlated with the expression levels of MGMT transcripts.
