Expression of integrin α3 and COX2 in human IDC (AMC sample set). (A) Immunostaining was performed and analyzed as in Figure 1. Images show representative scoring intensities (range of 0-3) for anti-α3 or anti-COX2 of adjacent regions from the same tumor, as indicated. Scale bar, 25 μM. (B) Table depicts co-distribution of like scores for α3 and COX2 among the 68 IDC samples, as in Figure 1. Spearman’s rank correlation coefficient (rs = 0.59 and p < 0.0001) indicates a significant correlation between α3 and COX2 expression (see Table 2).
