Fig. 3From: Stage-dependent angiopoietin-Tie2 and nitric oxide signaling of erythrocytes in response to surgical trauma in head and neck cancerComparisons of Tie2 phosphorylation levels in the erythrocyte membrane before and after surgery in cancer patients. a A representative gel was shown. b Intensity ratio of Tie2 receptor protein tyrosine phosphorylation relative to total Tie2 receptor protein. Tie2 tyrosine phosphorylation level was significantly downregulated after surgery in cancer patients. n = 10, **p < 0.01Back to article page
