Of these, 18 (75%) were invasive ductal carcinomas and 16 (88.9%) exhibit a positive signal (Fig. 2C, D and supplementary table 7a) for CTGF while 5 (83.3%) of the 6 analyzed normal breast tissues were negative for CTGF (Fig. 2C, D and supplementary table 7a). Here, CCN2 is linked to invasive ductal breast carcinoma.
