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
