Furthermore, very similar uptake and internalization of [68Ga]Ga-PSMA-11 and [177Lu]Lu-PSMA-617 were demonstrated by PC3-PIP cells (Umbricht et al. 2017), this finding was also used in the reasoning by Lückerath et al. (2018) to transfer the tumor uptake measured by means of [68Ga]Ga-PSMA-11 on [177Lu]Lu-PSMA-617. The gene discussed is FOLH1; the disease is neoplasm.
