Figure 4. The protein expressions of S100A16, MMP2, N-cadherin and E-cadherin between adjacent tissues and NSCLC tissues (n = 92 for each). (A) Western blot was used to determine the protein expression. GAPDH was used as the loading control. The expressions were normalized to adjacent (B–E). Violin plot was used to show the data. *p < 0.05, **p < 0.01, ***p < 0.001 from unpaired t-test with Welch’s correction.
