Identification of an inhibitory mechanism of luteolin on the insulin-like growth factor-1 ligand-receptor interaction

Using single-molecule force measurement and fluorescence imaging, we have demonstrated that luteolin has an inhibitory effect on IGF-1 ligand-receptor binding, the initial step in IGF-1 signaling. This inhibition mechanism, which was confirmed by flow cytometry and molecular docking, could play a role in cancer therapy.
