The same pattern was seen in TIA of lung carcinoma tumors, where there was a degradation of the overall ECM, although less prominent (83.4 ± 8.1% for laminin, 58.3 ± 8.1% for collagen IV and 80.7 ± 16% for collagen I)—except for fibronectin, which was overexpressed (117.8 ± 25.3%). This evidence concerns the gene FN1 and lung carcinoma.
