We have previously shown that the HER2-specific affibody molecule (ZHER2∶342)2 inhibits proliferation of SKBR-3 cells. Here, we continue to investigate its biological effects in vitro by studying receptor dimerization and clonogenic survival following irradiation. We found that (ZHER2∶342)2 sensitizes the HER2-overexpressing cell line SKBR-3 to ionizing radiation. The survival after exposure to (ZHER2∶342)2 and 8 Gy (S8Gy 0.006) was decreased by a factor four compared to the untreated (S8Gy 0.023). The low HER2-expressing cell line MCF-7 was more radiosensitive than SKBR-3 but did not respond to (ZHER2∶342)2. Treatment by (ZHER2∶342)2 strongly increased the levels of dimerized and phosphorylated HER2 even after 5 minutes of stimulation. The monomeric ZHER2∶342 does not seem to be able to induce receptor phosphorylation and dimerization or sensitize cells to irradiation.
