Through its various targets, MMP1 promotes not only tumor invasion but also breast cancer colonization to bone by mechanisms that include the release of membrane - bound EGF - like growth factors from tumor cells, leading to activation of EGF receptor signaling and suppression of OPG expression in osteoblasts, which in turn promotes the differentiation and activation of osteoclasts required for bone destruction and enhanced tumor growth in the bone microenvironment (32).

Finally, in collaboration with physicists from the Institute Curie, we are also investigating if, in addition to cellular and biochemical tumor microenvironment, mechanical pressure imposed by stroma can stimulate invasion of cancer cells.
