Repulsive guidance molecule a (RGMa), which binds to its receptor neogenin, has been well determined as a repulsive axon guidance molecule. However, whether RGMa affects the growth of hippocampal mossy fibers, the axons of dentate granule cells, has been unknown. In the present study, we found that the primary neurons in the hippocampus express both RGMa(More)
Matrix metalloproteinase-13 (MMP-13) plays a critical role in parathyroid hormone (PTH)-induced bone resorption. PTH acts via protein kinase A (PKA) to phosphorylate and stimulate the transactivation of Runx2 for MMP-13 promoter activation. We show here that PTH stimulated Runx2 phosphorylation in rat osteoblastic cells. Runx2 was phosphorylated on serine(More)
