Evaluating in Vivo PARP-1 Expression With 18F-FluorThanatrace Positron Emission Tomography (PET/CT) in Prostate Cancer

Fluorine-18 labeled FluorThanatrace \[18F\]FTT can be synthesized with high specific activity so the quantity of mass injected with the radiopharmaceutical is \< 10 μg.

Poly(ADP-ribose) polymerase (PARP) is a family of enzymes involved in base excision repair (the repair of DNA single-strand breaks) and alternative end joining (repair of DNA double-strand breaks). The molecular basis of PARP1 inhibitor function may depend on the dual roles of PARP1 as a modulator of gene transcription in addition to DNA damage repair 3.
