There are a couple of papers reporting the safety of different NaA nanozeolite nanomolecules including NaA-silane-PEG or its prostate-specific membrane antigen (PSMA) targeting match—NaA-silane-PEG-D2B—in normal prostate cell lines (RWPE-1, HPrEC) and in prostate cancer cell lines (LNCaP C4-2, DU-145) [56,102]. The gene discussed is FOLH1; the disease is Familial prostate cancer.
