MMP9 and non-small cell lung carcinoma: Figure 8 demonstrates that PAM treatment downregulated the protein expression levels of RAS, ERK, p-ERK, N-cadherin, vimentin, matrix metalloproteinase-2 (MMP-2), and matrix metalloproteinase-9 (MMP-9) in NSCLC cells while upregulating the protein expression level of E-cadherin.
