<p>PTX3 expression in breast cancer cells is associated with stem-like features and epithelial-mesenchymal transition. <bold>(A)</bold> Tumorsphere formation of MCF-7 and MDA-MB-231 cells. MCF-7 and MDA-MB-231 cells were treated with siPTX3 or rhPTX3 for 14 days, and tumor spheres expansion were analyzed at 40x magnification under a microscope (bar = 50&#xb5;m; magnification, 400x). <bold>(B)</bold> PTX3 promotes cell migration and invasion in breast cancer. MCF-7 and MDA-MB-231 cells were treated with either siPTX3 or rhPTX3. The migration and invasion abilities of the cells were examined by migration and invasion assay (Transwell assay). <bold>(C, D)</bold> Effect of PTX3 on stem-like features and epithelial-mesenchymal transition markers. siPTX3 or rhPTX3-treated MDA-MB-231 and MCF-7 cells were lysed and subjected to 12% SDS-PAGE and analyzed by western blotting with antibodies against PTX3, Oct4, Sox2, E-cadherin, N-cadherin, and Snail. GAPDH was used as an internal control. The data was statistically significant at *P &lt; 0.05 as compared to control. Data are represented as mean &#xb1; SEM of three independent experiments.</p>
