Sikora Lab

The overall goal of the Sikora Laboratory is to understand mechanisms of response and resistance to steroid hormones and anti-estrogen therapies in breast cancer. Projects in the laboratory revolve around two major efforts toward this goal: a) understanding the unique biology and estrogen receptor (ER) signaling of invasive lobular carcinoma (ILC, an understudied breast cancer subtype), and b) understanding the role of hormone receptor signaling in the development of anti-estrogen therapy resistance.

 

Current projects in these areas include:

  • Elucidating the signaling network driven by ER and the Wnt ligand WNT4 in ILC
  • Characterizing mechanisms controlling the unique ER transcriptome in ILC
  • Identifying novel therapeutic strategies targeting ILC cells
  • Characterizing hormone receptor signaling in breast cancer during anti-estrogen therapy
  • Developing new models to study the emergence of anti-estrogen therapy resistance
