Invasive cancer cells marked by distinctive mutations

What does it take to be a leader – of cancer cells?

Adam Marcus and colleagues at Winship Cancer Institute are back, with an analysis of mutations that drive metastatic behavior among groups of lung cancer cells. The findings were published on the cover of Journal of Cell Science, and suggest pharmacological strategies to intervene against or prevent metastasis. Dr. Marcus is a faculty member in the BCDB and CB Programs.

Marcus and former Cancer Biology graduate student Jessica Konen previously developed a technique for selectively labeling “leader” or “follower” lung cancer cells in culture, using lasers that turn a fluorescent protein from green to red. The leaders are more adventurous and invasive, but the followers support the leaders and help them survive.

The new research harnesses their technique to track the mutations that are specific to leader or follower cells. It was a collaboration with the lab of Paula Vertino, formerly at Winship and now at University of Rochester. Cancer Biology graduate students Elizabeth Zoeller and Brian Pedro led the work, with sophisticated genomics from former GMB graduate student Ben Barwick.
