The greatly increased risk of cancer and cancer mortality with aging may be due in part to the buildup in the body of a key cancer-promoting molecule, according to new preclinical research from scientists at Weill Cornell Medicine.
Three proteins bind to chemical marks on molecular messages in cells, targeting the messages for degradation, according to researchers at Weill Cornell Medicine. The results overturn some prevailing models of how cells use chemical tags to control their genes' expression and may offer new targets for treating leukemia, which can arise when the chemical tags go awry.
