Abstract

Ets-1 transcription factor overexpression in breast cancers is associated with invasive features and is associated with a poor prognosis. Beyond its role in driving carcinoma cell invasion, in this study, we wished to determine whether Ets-1 overexpression in cancer cells promotes angiogenesis by creating a paracrine pro-invasive environment for endothelial cells as well. To address this question, we set up different co-culture models of cancer cells with endothelial cells. Conditioned media from cancer cells induced endothelial cell proliferation, migration and morphogenesis in matrix models. Of note, co-culture assays in three-dimensional matrix models also revealed the reciprocal induction of cancer cell morphogenesis by endothelial cells, in support of an angiocrine action on tumor cells. Ets-1 emerged as a key regulator of the angiogenic potential of breast cancer cells, favoring their ability to induce, in a paracrine manner, the morphogenesis of endothelial cells and also to physically interact with the latter. Nevertheless, Ets-1 overexpression in cancer cells also restrained their chemoattractive potential for endothelial cells both in Boyden chambers and in ex vivo 3D co-cultures. Finally, Ets-1 modulation in breast cancer cells qualitatively altered the angiogenic pattern of experimental in vivo tumors, with a balance between vessel recruitment and intratumoral small capillaries sprouting. Taken together, our data highlight a critical and intriguing role for Ets-1 in the angiogenic potential of breast cancer cells, and reveal another facet of Ets-1 oncogenic activities.
