NIH-funded research R01 grant

Investigating resistance to anti-estrogen therapy in aggressive breast cancer.

Official title: WNT pathway-driven anti-estrogen therapy resistance in breast cancer

Funded at Thomas Jefferson University · NIH-11083025 · Data updated 2026-11-12

This study is looking at a tough type of breast cancer called lumino-basal breast cancer, especially in women under 50, to find out why some treatments that block estrogen don’t work well, with the hope of discovering better ways to help those affected.

Who could benefit from this research

Could help

Ideal candidates for this research are young women under 50 diagnosed with estrogen receptor-positive lumino-basal breast cancer.

Less likely to help

Patients with other types of breast cancer or those who are not estrogen receptor-positive may not benefit from this research.

What this research studies

This research focuses on a specific type of aggressive breast cancer known as lumino-basal breast cancer (LBBC), which is characterized by a mix of estrogen receptor-positive and negative cells. The study aims to understand how these cancers resist anti-estrogen therapies, particularly in younger women under 50. By examining the role of certain hormones and signaling pathways, the research seeks to identify mechanisms that contribute to therapy resistance. Patients may benefit from insights that could lead to more effective treatment strategies tailored to this aggressive cancer subtype.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options for patients with therapy-resistant breast cancer.

How similar studies have gone: Previous research has shown promising results in understanding therapy resistance in breast cancer, but this specific approach targeting LBBC is relatively novel.
