Breast cancer cells grow, spread and resist treatment by reading signals from inside and outside the cell. Most breast cancers depend on the estrogen receptor, a protein that drives growth in response to the hormone estrogen.

Grants

What they work on

  1. Determine how the Hippo pathway, through the LATS1/2 kinases, controls transcription of ESR1, the main estrogen receptor gene, in breast cells and what ESR1 contributes to Hippo biology in breast tissue.
  2. Test whether blocking LATS1/2 both slows ER+ breast cancer growth by lowering ESR1 and makes cancer cells more visible to the immune system, improving immunotherapy.
  3. Define how a stiff extracellular matrix activates the LYN kinase so that TWIST1, a protein that switches on cell-migration genes, enters the nucleus and drives epithelial-mesenchymal transition (EMT).
  4. Uncover how soft matrix keeps TWIST1 out of the nucleus and blocks EMT, revealing the other half of the stiffness-sensing switch in breast cancer cells.
  5. Test whether the TWIST1 mechanotransduction pathway drives metastasis in living animals and whether it predicts progression in human breast cancer.

More about the research

Drugs that block this receptor work at first, but tumors often become resistant. Tumors that spread to distant organs (metastasis) are also hard to treat. The projects here ask how two kinds of signals control breast cancer: a growth-control pathway that switches the estrogen receptor gene on, and the physical stiffness of the tissue around a tumor.

Why it matters

Patients with estrogen receptor–positive breast cancer often stop responding to hormone therapy, and metastasis drives most cancer deaths. This work could supply a basis for treating ER+ breast cancer with drugs that block the LATS1/2 kinases, possibly alongside immunotherapy. It could also reveal new targets in the stiffness-sensing LYN–TWIST1 pathway for drugs that slow tumor spread.
