Pathway links inflammation, angiogenesis and breast cancer
... In the Cell paper, researchers show IKK does its damage
working in the cytosol of the cell, the internal fluid outside of the nucleus. Together, the two kinases previously were known to free the oncoprotein nuclear factor kappa B (NF"B) from the cytosol, allowing it to move to the nucleus and activate gen...
