Relationship between nuclear expression of p-c-Jun, TCF4 and β-Catenin and the pT and pN stages in adenocarcinomas (n = 35). a) p-c-Jun expression was significantly negatively correlated with the pT stage progression (T1-2, n = 11; T3-4, n = 24). b) No significant correlation was observed between p-c-Jun, TCF4 and β-Catenin expression, and the pN stage (N0, n = 20; N1-3, n = 15). Horizontal lines, median; boxes, 25% to 75% range; brackets, 10% to 90% range; circles, points outside the 10% to 90% range. *p < 0.05 by Mann-Whitney U test.
