Single-molecule tracker illuminates workings of cancer-related proteins
Researchers at the Broad Institute have developed a new imaging technique to track cancer-related proteins in real-time. This method utilizes stable nanoparticle probes to observe the dynamics of receptor interactions within living cells. The findings could enhance drug screening and provide insights into cancer mechanisms.
- ▪The research team created a powerful single-molecule imaging method to study protein interactions.
- ▪They used long-lasting nanoparticle probes to track EGFR and related receptors in living human cells.
- ▪The study revealed how mutations in EGFR can lead to more stable dimers, contributing to cancer growth.
