Cover Story: Growth hormone (GH) is significant in contributing to the resistance to chemotherapy. We identified that GH-treated melanoma cells release exosomes carrying elevated protein levels of ABC transporters (ABCC1 and ABCB1), N-cadherin, and MMP2. When these exosomes are administered to recipient melanoma cells, they decrease drug retention and enhance cell migration. Blocking GH action with the GH receptor antagonist pegvisomant attenuates these GH-induced exosomal protein levels, improving chemotherapy treatment and decreasing cell migration in recipient cells. These findings highlight the role of GH in inducing exosome-mediated drug resistance and cell migration. Inhibiting GH action reverses these effects, restoring drug sensitivity and reducing cell migration.
