In our previously published studies [24], [26], [27], [33] we showed that WAVE3 is highly expressed in the aggressive MDA-MB-231 BC cells, and that WAVE3 activity is required for the invasion of these cells both in vitro as well as in in vivo mouse models for breast cancer tumor progression and metastasis [24], [26], [27], [33]. Here, WASF3 is linked to breast cancer.
