FOLH1 and neoplasm: The survival of PC-3 flu cells was, however, affected at radioligandconcentrations of 1 MBq/mL and higher, with a tendency of a more pronounced effectfrom 161Tb-PSMA-617 (p > 0.05) (Fig. 1c/d).The viability and survival of PC-3 PIP tumor cells exposed to161Tb-DPTA and 177Lu-DTPAwere not affected, and showed only a marginal reduction at higher radioligandconcentration, which was equal for both radionuclide complexes (p > 0.05) (Fig. 1e/f).
