And we verified that the expression of MMP1 in NSCLC tissues was significantly higher than that in normal tissues, via the datasets GSE7670 (P = 8.01E-10, Fold Change = 21.925) and GSE10072 (P = 1.12E-15, Fold Change = 7.277) in Oncomine (Fig. 3c and d). Here, MMP1 is linked to non-small cell lung carcinoma.
