Figure 2. Radiations enhance STAT3 activation mainly by S727 phosphorylation.
(A) Western blot analysis of STAT3 phosphorylation status 24 h after treatment at increasing doses of radiations in GSC-2 and GSC-11. (B) Quantification of experiment presented in (A). Histogram represents the mean ± standard error of the mean of 6 independent experiments (*p < 0.05; **p < 0.01; Mann-Whitney test).
