Fig 6. DNA-PKcs ps2056 is present in human medullary thyroid cancer and correlates with RET signaling.
Immunohistochemistry analysis of tissue microarrays containing normal and MTC samples for phospho-s2056 (ps2056) and phospho-RET (pRET). Each tissue sample was given a score of 0 (no signal), 1 (weak), 2 (moderate), 3 (high) for ps2056 levels. Images represent a score of 3. *chi test p ≤ 0.01 for normal vs tumor ps2056, ** p ≤ 0.01 for normal vs. tumor +ps2056 +RET.
