TIMP1 and non-small cell lung carcinoma: In NSCLC, KDM1A expression was more significantly negatively correlated with TIMP3 expression (r = −0.2048, P < 0.0001), than with the other TIMPs: TIMP2 (r = −0.0791, P = 0.0506) (Figure 3B), TIMP1 (r = −0.1285, P = 0.0034), and TIMP4 (r = −0.11, P = 0.0724) (TIMP1 and TIMP4 are not shown).
