7、. Sulindac combined with vitamin C significantly increases PUMA levels, but shows no effect onBim, Bcl-2 and Mcl-1 levels2. Sulindac (MK-231) (500 M) in combination with celecoxib blocks transforming growthfactor (TGF)-1-induced epithelial-mesenchymal transition, migration and invasion in A549 cells
