As shown in Figure 4 A&B, western blots were performed to examine the expression level of c-Met in these 27 pair samples, c-Met expression was significantly higher in NSCLC tissues compared with NATs (paired T-test, P<0.001, t = 6.352), while miR-449a was down-regulated in the same panel of NSCLC tissues as detected in Result 1(Figure 4C). Here, MET is linked to non-small cell lung carcinoma.
