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.
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.
The membrane type I-matrix metalloproteinase is essential for the release of collagen fibrils from plasma membrane fibripositors, which is required for the transition from embryonic to postnatal tendon development.
Certain types of 3D chromatin loops are easy to predict from existing or easily obtainable 2D information, which benefits gene expression studies in tissues/cells/organisms without extensive pre-existing 3D information.
Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.
