Induction of an abortive and futile DNA repair process in E. coli by the antitumor DNA bifunctional intercalator, ditercalinium: role in polA in death induction.

abstract：:p73, the p53 homologue, exists as a transactivation-domain-proficient TAp73 or deficient deltaN(DN)p73 form. Expectedly, the oncogenic DNp73 that is capable of inactivating both TAp73 and p53 function, is over-expressed in cancers. However, the role of TAp73, which exhibits tumour-suppressive properties in gain or los...
