NFYA and breast cancer: We sorted CD44low/CD24high (HMLE-Epi cells) and CD44high/CD24low (HMLE-Mes cells) cells from HMLE cells and examined the EMT status and NFYA expression. Similar to the results of breast cancer cell lines, NFYAv1 expression correlated with vimentin, whereas NFYAv2 correlated with E-cadherin (Supplementary Fig. 1b, c).
