[ 18 F]FE-OTS964: a Small Molecule Targeting TOPK for In Vivo PET Imaging in a Glioblastoma Xenograft Model

Purpose Lymphokine-activated killer T cell-originated protein kinase (TOPK) is a fairly new cancer biomarker with great potential for clinical applications. The labeling of a TOPK inhibitor with F-18 can be exploited for positron emission tomography (PET) imaging allowing more accurate patient identification, stratification, and disease monitoring.
