Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...

Researchers engineered RNA micelles carrying gemcitabine, survivin-targeting siRNA and a tumor-binding ligand. In mice with ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

Researchers identified miR-149-5p as overexpressed in progressive bronchial premalignant lesions. The microRNA suppresses ...

(Boston)—Throughout a person’s lifetime, the cells lining the respiratory tract are exposed to inhaled pollutants, including cigarette smoke. These exposures can cause molecular changes that disrupt ...

Throughout a person's lifetime, the cells lining the respiratory tract are exposed to inhaled pollutants, including cigarette smoke. These exposures can cause molecular changes that disrupt normal ...

A new study in mice hints at the potential to use tiny particles made with RNA molecules to deliver chemotherapy drugs and other therapies directly to tumors, killing cancer cells without generating ...

Men tend to lose the Y chromosome from some of their cells as they age — a process once thought to be harmless because the Y carries relatively few genes beyond those involved in male determination.
