While our analysis of alterations in breast cancer samples confirms that mRNA upregulation or gene amplification of Mena frequently occurs in all types of invasive breast cancer (Fig. 1B), Kaplan-Meier Plot analysis of a set of 3455 patients for relapse-free survival (Fig. 1A) did not suggest any correlation between Mena expression levels and patient survival. This evidence concerns the gene ENAH and breast cancer.
