Current Research

  • Seeking to improve outcomes in breast cancer by identifying aberrant cell processes that lead to tumor formation and progression.

  • Laboratory studies are conducted to test strategies to kill cancer stem cells by targeting a critical mediator of inflammation.

  • These studies could lead to new treatments for metastatic, basal-like/triple negative breast cancer.

Triple negative breast cancer (TNBC) is a subgroup of breast cancers that can be broken into other subgroups based on molecular characteristics. Some TNBC are more aggressive than others. Basal-like triple negative breast cancer is a particularly aggressive disease with a likelihood of spreading to other tissues – a process called metastasis. Drs. Gradishar and Cyrns have identified a protein that is driving part of this aggressive behavior. They are conducting laboratory studies to understand how it promotes metastasis for the development of new targeted therapies for patients with TNBC.

Full Research Summary

Basal-like tumors, which include those classified as triple negative, are clinically aggressive and lack targeted therapies. 

Drs. Gradishar and Cryns and their colleagues have shown that a cell stress protein called alphaβ-crystallin contributes to the aggressive behavior of basal-like/triple negative tumors and regulates breast cancer metastasis to organs such as the brain. 

Recently, the team showed that alphaβ-crystallin promotes survival of breast cancer stem cells (BCSC), specialized cells that are suspected to driver metastasis, suggesting that alphaβ-crystallin may be a target for stopping metastasis. It does this by increasing expression of a molecule called IL-6, a molecule involved in inflammatory response. 

During the next year, the team will continue to examine the role of the alphaβ-crystallin/IL-6 network on BCSCs and metastasis and determine whether alphaβ-crystallin expression correlates with other markers of BCSCs. These studies could lead to new treatments for metastatic basal-like/triple negative breast cancer.
