    IGF1R plays a complex role in breast cancer, influencing both tumor aggressiveness and cell adhesion dynamics.

  • 2

    IGF-1 stimulation enhances adhesion in MDA-MB-231 TNBC cells, while IGF1R knockdown also increases adhesion.

  • 3

    Inhibition of IGF1R signaling reduces adhesion to endothelial cells, highlighting its role in metastasis.

  • 4

    The study suggests that surface-bound IGF1R inhibits β1 integrin function, affecting cancer cell adhesion.

  • 5

    Both IGF-1 stimulation and IGF1R knockdown lead to increased adhesion through β1 integrin dependency.
