Drug Strategy Makes Cancer Genes Get Lost in Translation

... machinery that does the translating, making it a challenge to determine where to begin, he added. In contrast, strong mRNAs have only short 5' untranslated regions that allow for easier protein formation. The successful translation of weak mRNAs therefore depends more heavily on other protein factors, ...
