Scientists Identify Critical Gene Factor in Heart Development

...oRNA miR-1-1 could not fully compensate for loss of miR-1-2. The team found that loss of miR-1-2 affected many functions in the heart, including heart morphogenesis and control of the number of cells in the heart. For example, half of the mice developed holes in the pumping chambers of the heart, which is the most...
