Fei-Liu-Ping ointment decreases NF-κB expression, N-Cadherin, and MMP9 expression and increases expression of E-Cadherin in vivo . Effect of FLP on the expression of NF-κB, E-cadherin, N-cadherin and MMP9. (A) Tumor tissue was collected from Lewis Lung xenograft was subjected to immunohistochemical analysis and stained for NF-κB, E-cadherin, N-cadherin, and MMP9 antibody, respectively. Data is shown as representative photomicrographs from each group (n = 10) at original magnification × 100. (B) Tumor tissue was collected from 10 mice per group, lysed and protein extracts were analyzed by Western blot for analysis for NF-κB, E-cadherin and MMP9. A representative blot is shown. Data analyzed using densitometry.
