In a new study Yingxian Li and her colleagues show that the microRNA miR-214 targets ATF4 in osteoblasts to negatively regulate their activity. Manipulating miR-214 levels experimentally showed that its elevated expression is sufficient to induce bone loss in mice and that its therapeutic inhibition reduces bone loss in two mouse models.
