Breast Cancer Cells Interact With Non-Cancerous Tissue To Drive Metastasis

In addition to mutations, created by the tissues surrounding tumors () play a major role in cancer progression.

In this issue of the Journal of Clinical Investigation, researchers led by Gregg Semenza at examined the interactions between breast cancer cells and the stroma to identify underlying pro-metastatic molecular mechanisms.

They found that both breast cancer cells and the stroma secrete proteins that influence the behavior of each cell type. Additionally, Semenza and colleagues found that a group of proteins known as HIFs were required for stroma-driven metastases, suggesting that drugs which inhibit this class of proteins may be useful in preventing .
