In Cancer Metastasis, DGK-Alpha Helps Cancer Cells Gain Traction And Mobilize
Posted from MedWorm: Biology 2 days ago
Biology : Biology News
Metastasizing cancer cells often express integrins that provide better traction. A new study in The Journal of Cell Biology reveals how a lipid-converting enzyme helps the cells mobilize these integrins. Adhesive integrin proteins continually cycle to and from the cell surface. Invasive cancer cells... (original story)
