McGill study links an immune-cell enzyme to early breast-cancer progression
Published by BriefDash · · Toronto
McGill researchers used mice, human breast tissue and laboratory-grown tumour models to investigate progression of ductal carcinoma in situ. Their October 20 report identifies an enzyme released by neutrophils that weakens a protective cell barrier. Blocking the cells or enzyme kept the barrier intact in the experimental models. The release does not announce a clinical diagnostic test.
Why it matters
The findings suggest a possible future marker of progression that requires further research.
