Effect of curcumin on EMT in A549R cells. A549R cells were treated with 0, 1, 2, 5, 10, or 20 μM curcumin for 48 h. (A) CCK-8 assays were used to detect cell viability. (B) Western blotting was used to analyze epithelial and mesenchymal marker expression levels in A549R cells. (C) sE-cad secretion was detected by ELISA. (D) A549R cells were exposed to 0, 1, 2, 5, 10, or 20 μM curcumin for 48 h, and cell morphology changes were observed with an optical microscope. The data are presented as the mean ± SD of 3 independent experiments. *p < 0.05.
