New Insights Into Molecular Mechanisms Of Fludarabine, Alina D. Bulgar

ETD Archive

Nucleotide analogs (e.g. fludarabine) are antimetabolites used in the treatment of a wide variety of hematological malignancies and solid tumors. Upon being metabolized to their active triphosphate form, these agents are incorporated into DNA. Among other molecular targets, their incorporation may lead to activation of base excision repair (BER) pathway. The molecular mechanism of BER recognition and repair of the incorporated fludarabine has not yet been elucidated. The main focus of this research was to study the involvement of BER pathway in the response to fludarabine induced DNA damage. Also, the possibility of enhancing antineoplastic activity of fludarabine by inhibition …
