For instance, in the 22RV1 tumor-bearing mice, we demonstrated that at the 0.1 × and 1 × dose levels, the SMG-R can be blocked by approximately 40% and at a statistically significant level without affecting the uptake of [18F]DCFPyL at the PSMA-positive tumor (Fig. 3e, f). Here, FOLH1 is linked to neoplasm.
