Proprotein convertase subtilisin/kexin Type 9 is required for Ahnak-mediated metastasis of melanoma into lung epithelial cells

Previously we demonstrated that Ahnak mediates transforming growth factor-β (TGFβ)-induced epithelial-mesenchymal transition (EMT) during tumor metastasis. It is well-known that circulating tumor cells (CTCs) invade the vasculature of adjacent target tissues before working to adapt to the host environments. Currently, the molecular mechanism by which infiltrated tumor cells interact with host cells to survive within target tissue environments is...
