Targeting tumors may help stop spread of breast, other cancers
(Medical Xpress) -- Cancer that has spread from the site of an original tumor to other places in the body is often viewed as a death sentence. But if there are just a few of those secondary tumors, called metastases, some ...

DGK-alpha helps cancer cells gain traction and mobilize
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.

Cell senescence does not stop tumor growth
Since cancer cells grow indefinitely, it is commonly believed that senescence could act as a barrier against tumor growth and potentially be used as a way to treat cancer. A collaboration between a cancer biologist from the ...
