Red blood cells have a tiny but effective protector -- microRNA

Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress. The study illustrates how microRNA fine-tunes gene activity.
