A periosteal Bmp2 signaling center couples bone length to bone width during development and must be reactivated by clinical bone anabolic therapies to reduce fracture risk and accelerate fracture repair.
An unbiased transcriptional profiling screen reveals the secreted matrix metalloproteinase MMP-1 is a transcriptional target of the ensheathing glial receptor Draper following acute axon injury in adult Drosophila.
Dark exposure lowers the MMP9 activation threshold, and subsequent light stimulation to an amblyopic eye is sufficient to induce proteolysis at thalamo-cortical synapses in deprived mouse visual cortex.
Macrophage production of MT1-MMP upon MI contributes to adverse cardiac remodeling and worsened function by promoting EndMT via TGFB, suggesting MT1-MMP inhibition as a therapeutic option for patients with MI.
Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.
The IGF2 mRNA binding protein-2/IMP2, overexpressed in many common cancers, drives cancer cell proliferation by increasing the abundance of IGF2 and the oncogene HMGA1, which controls a network of effectors that enhance IGF2 action.
