Scientists Use Nanoparticles to Shut Down Mechanism that Drives Cancer Growth

July 7, 2015 9:50 am | by UCLA | News | Comments

When scientists develop cancer therapies, they target the features that make the disease deadly: tumor growth, metastasis, recurrence and drug resistance. In epithelial cancers — cancers of the breast, ovaries, prostate, skin and bladder, which begin in the organs’ lining — these processes are controlled by a genetic program called epithelial–mesenchymal transition.
