Curcumin inhibits the metastasis of K1 papillary thyroid cancer cells via modulating E-cadherin and matrix metalloproteinase-9 expression
The anti-metastatic effect of curcumin on papillary thyroid cancer K1 cells and its underlying mechanisms were investigated. Curcumin at 12.5, 25 and 50 mu M promoted mesenchymal-epithelial transition and decreased the migration rate of K1 cells by 24-87 %. Its mechanism may involve the up-regulation of E-cadherin expression levels and down-regulation of the activity and expression of matrix metalloproteinase-9.
