Pharmacological CK2 inhibitor CX-4945 inhibits clonogenic survival and sphere formation by HNSCC. CK2 inhibitor CX4945 inhibits clonogenic survival (A) and sphere formation (B) of UM-SCC-1 and UM-SCC-46 lines in a dose dependent manner between 0.5 to 5 μM in 3 replicate experiments. *Students t test, P < .05. C. Photomicrographs showing CX-4945 inhibition of colony formation in UM-SCC-46. D. Photomicrographs showing CX-4945 inhibition of tumor sphere formation in UM-SCC-1 and -46.
