Understanding SEMA7A's Role in Breast Changes After Pregnancy and Cancer Development

SEMA7A in postpartum mammary gland development and cellular transformation

NIH-funded research University of Colorado Denver · NIH-11128675

What this research studies

Pregnancy offers some protection against breast cancer, but there's a temporary increase in risk right after birth, especially for women over 30 at their first pregnancy. Breast cancers diagnosed within 5-10 years of childbirth, known as postpartum breast cancers (PPBC), are often more aggressive and likely to spread. This project aims to understand why PPBCs are more aggressive by looking at a specific protein, SEMA7A, which is found at high levels in these tumors. By learning more about SEMA7A's role in the breast after pregnancy, we hope to find new ways to understand and potentially treat these aggressive cancers.

Who could benefit from this research

Good fit: This foundational research focuses on understanding the biology of postpartum breast cancer, which affects women who have given birth, particularly those diagnosed within 5-10 years of childbirth.

Not a fit: Patients whose breast cancer is not related to postpartum changes or SEMA7A expression may not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new insights into why postpartum breast cancers are aggressive and help identify new targets for treatment.

How similar studies have performed: Preliminary data from this team suggest SEMA7A is present in mammary cells during postpartum changes and in aggressive tumors, indicating a promising area for further investigation.
