Common cancer protein may be therapeutic target, study finds
A study from Brunel University of London suggests that the Ki-67 protein, commonly used to assess tumor aggressiveness, may also play a role in preventing chromosome errors that lead to cancer. The research indicates that Ki-67 helps maintain the structural integrity of chromosomes during cell division. This discovery opens up potential avenues for new cancer therapies targeting Ki-67.
- ▪Ki-67 is routinely measured by doctors to evaluate tumor aggressiveness.
- ▪The study found that Ki-67 helps maintain genome stability during cell division.
- ▪Removing Ki-67 and other proteins led to chromosome errors, which are linked to cancer.
