PDGFRB and lung adenocarcinoma: We have previously shown that SLURP-1 inhibits migration of lung adenocarcinoma A549 cells via interaction with α7-nAChR/EGFR/PDGFR complexes, while the anti-migration activity of Oncotag in A549 cells depends solely on interaction with α7-nAChR (Bychkov et al., 2021).
