FLP rescues E-cadherin and inhibits N-cadherin expression in vitro . Effects of FLP treatment on E-cadherin and N-cadherin expression by immunofluorescence under inflammatory conditions. Photomicrographs of A549 cells stained with (A) E-cadherin, (B) N-cadherin, respectively counterstained with DAPI after pre-treatment with NRS (Vehicle control) or FLP. Representative pictures at original magnification × 400 were shown. All experiments were repeated 3 times.
