Salk Scientists Identify Factors That Trigger ALT-Ernative Cancer Cell Growth

Highly diverse cancers share one trait: the capacity for endless cell division. Unregulated growth is due in large part to the fact that tumor cells can rebuild protective ends of their chromosomes, which are made of repeated DNA sequences and proteins. Normally, cell division halts once these structures, called telomeres, wear down. But cancer cells keep on going by deploying one of two strategies to reconstruct telomeres.
