Stretches of repeating DNA tied to cancer progression and survival

(University of Washington Health Sciences/UW Medicine) Short, unstable DNA stretches, composed of repeated code, may play a greater role in the development and progression of cancer than once thought. These sites are mutation-prone, a tendency that increases in cancer. Using the Cancer Genome Atlas, researchers employed a new technique to analyze sequences of all genes in nearly 6,000 tumors from 18 different kinds of cancer.
