The cancer gene RhoC is directly connected to breast cancer stem cell metastasis, according to a new University of Michigan Comprehensive Cancer Center study published in PLoS One. Scientists previously determined that the gene promoted metastasis for multiple cancer types. But it turns out that the gene increases as breast cancer progresses. And the higher the levels, the worse patient survival rates, researchers say. But having made the connection, researchers believe that targeting RhoC could manage the cancer stem cell proliferation and help treat the disease in a more targeted fashion. Release
