MMP2 and non-small cell lung carcinoma: Pearson correlation coefficient analysis revealed that mRNA levels of S100A16 were positively correlated with MMP2 (r=0.32) and N-cadherin (r=0.30) respectively (Figure 3A, 3B), and negatively correlated with E-cadherin (r=-0.43) (Figure 3C) in NSCLC tissues.
