The report from Hou et al [22], showed that expression of EGFR, MMP9 and TGFβ-1 were all upregulated in human lung cancer samples, including LCL (large cell lung cancer), ADC (adenocarcinoma) and SCC (squamous cell carcinoma), compared to adjacent normal tissues (N) (Figure 8D–8F). Here, MMP9 is linked to lung carcinoma.
