Colon cancer researchers target stem cells, discover viable new therapeutic path
Date:12/1/2013

xt, the team used an existing small-molecule inhibitor to successfully block BMI-1, thus demonstrating the clinical relevance of this approach.

Lead author Dr. Antonija Kreso writes: "Inhibiting a recognized regulator of self-renewal is an effective approach to control tumor growth, providing strong evidence for the clinical relevance of self-renewal as a biological process for therapeutic targeting."

Dr. Dick explains: "When we blocked the BMI-1 pathway, the stem cells were unable to self-renew, which resulted in long-term and irreversible impairment of tumour growth. In other words, the cancer was permanently shut down."

Surgeon-scientist Dr. Catherine O'Brien, senior co-author of the study says: "The clinical potential of this research is exciting because it maps a viable way to develop targeted treatment for colon cancer patients. It is already known that about 65% have the BMI-1 biomarker. With the target identified, and a proven way to tackle it, this knowledge could readily translate into first-in-human trials to provide more personalized cancer medicine."
