Abstract:
The invention provides methods for enhancing efficiency of prodrugs by specifically engineered enzymes with enhanced activity towards nucleoside analogs used in cancer chemotherapy, and delivering the enzymes to specific target cells in a patient. The invention also provides modified deoxycytidine kinase (dCK) mutants with such enhanced activity. Furthermore, the invention provides antibody-conjugated enzymes that can be specifically delivered to leukemic blast cells in vivo or ex vivo.

Abstract:
Embodiments of the invention include a PET/SPECT reporter gene system that uses enhanced non-immunogenic versions of a human mitochondrial thymidine kinase 2 expressed in cytoplasm to preferentially trap novel PET/SPECT radiolabeled L and D-enantiomer analogs of the natural substrate thymidine. Such highly sensitive, non-immunogenic reporter genes function in combination with a set of novel, radiolabeled probes in whole body molecular imaging applications using positron emission tomography (PET) or single photon emission computed tomography (SPECT).
Abstract:
The invention relates to a composition comprising: a stably integrating delivery vector; a modified mammalian thymidylate kinase (tmpk) wherein the modified mammalian tmpk increases phosphorylation of a prodrug relative to phosphorylation of the prodrug by wild-type human tmpk. The invention also relates to use of these compositions in methods of treatment of diseaseuuius such as graft versus host disease and cancer.
