1. Phosphorylation of Twist1 in human breast cancer cell lines and tumors.
Phosphorylation of Twist1 in human breast cancer cell lines and tumors. A, Twist1 mRNA was analyzed in 9 human breast cancer cell lines categorized by different HER2 level (on the basis of the published data). Met, metastatic; non-Met, nonmetastatic. B, immunoblot analysis of Twist1 phosphorylation in breast cancer cell lines with distinct metastatic potential and known genetic background. C, 4T1 cells, 4T1 tumors, and invasive human breast tumors including IDC/ILC types were stained for phospho-Twist1, Akt-pS473, and prometastatic marker TNC. Scale bars, 20 μm and 50 μm, respectively. D, pathologic statistics of 1,532 invasive human breast tumors that have phospho-Twist1. Cells with > 30% stained were considered positive.
