What this research studies

This project will build a high-resolution method that combines tissue imaging with long-read RNA sequencing to capture full-length RNA isoforms in place within breast tissue. Scientists will apply this approach to aging, pre-neoplastic breast tissues to see where and when alternative splicing changes occur in the tissue microenvironment. By comparing patterns across ages and tissue regions, they hope to identify molecular alterations that happen before a tumor forms. The work uses human breast samples and lab methods to link age-related RNA changes to early steps in cancer development.

Who could benefit from this research

Good fit: Ideal candidates would be older adults or people undergoing breast surgery or biopsy who are willing to donate tissue samples for research.

Not a fit: People seeking immediate therapeutic benefit or new treatments are unlikely to benefit directly because this is a laboratory and tissue-based research program rather than a treatment trial.

Why it matters

Potential benefit: If successful, this could reveal early molecular signs of breast cancer risk and point to new targets for prevention or earlier detection.

How similar studies have performed: Spatial transcriptomics has helped map gene expression in cancers, but combining spatial maps with long-read isoform profiling in aging pre‑cancer tissues is novel and largely untested.
