Destroying bad seeds
Scientists have found a microRNA that blocks the development of breast-cancer stem cells
Cancer stem cells are thought to be the 'bad seeds' of cancer. They are the only cells capable of giving rise to new
tumours and are resistant to chemotherapy. Destroying cancer stem cells could potentially block cancer development.
Erwei Song at Sun Yat-sen University in Guangzhou, Judy Lieberman at Harvard Medical School and co-workers1 showed that
breast-cancer stem cells could be blocked from self-renewal and differentiation through the interference of let-7
microRNAs.
