| Open AccessSOXC are critical regulators of adult bone mass
Angelozzi et al. uncover key mechanisms involved in physiological and pathological bone mass remodeling by showing that SOXC transcription factors regulate the bone formation and resorption balance via critical roles in LepR+ mesenchymal stem cells.

| Open AccessRegulation of bone homeostasis by MERTK and TYRO3
The TAM family of receptor tyrosine kinases exerts pleiotropic functions in health and disease. Here, the authors show that TAM receptors control osteoblastic bone formation and identified MERTK as a novel target for bone anabolic therapy and mitigation of bone metastasis including its associated osteolytic bone disease

| Open AccessControl of osteocyte dendrite formation by Sp7 and its target gene osteocrin
The molecular circuitry that drives dendrite formation during osteocytogenesis remains poorly understood. Here the authors show that deletion of Sp7, a gene linked to rare and common skeletal disease, in mature osteoblasts and osteocytes causes severe defects in osteocyte dendrites.

| Open AccessA functional motif of long noncoding RNA Nron against osteoporosis
LncRNAs are implicated in the pathogenesis of a number of diseases. Here, the authors show that the lncRNA Nron suppresses bone resorption, and show that delivery of a functional motif of Nron increases bone mass in mouse models of osteoporosis.

| Open AccessInhibition of osteoblastic Smurf1 promotes bone formation in mouse models of distinctive age-related osteoporosis
BMP promotes bone formation but its efficacy is limited in some patients. Here, the authors show that osteoporosis patients with a poor response to BMP have increased expression of Smurf1, which targets BMP effectors for degradation, and demonstrate that its chemical inhibition enhances BMP-mediated bone formation in mice.
