CK2 activity in squamous cell carcinoma of the head and neck versus normal mucosa
CK2 activity was measured in subcellular fractions of 20 SCCHN tumors (â—¯) and in six specimens of normal upper aerodigestive tract mucosa (â–¡): CK2 activity in SCCHN subcellular fractions was significantly elevated in both nuclear (20.3 versus 3.7; p < 0.0005) and cytosolic (5.9 versus 0.6; p < 0.0034) compartments relative to normal mucosa. (A) CK2 activity in soluble nuclear proteins. (B) CK2 activity in cytosol.
