Atypical cadherin Celsr3, a regulator of planar cell polarity, is critical for the development of the axonal blueprint. We previously showed that expression of Celsr3 is necessary to establish forebrain connections such as the anterior commissure and thalamocortical and corticospinal tracts. The requirement for Celsr3 during hippocampal wiring and its(More)
Brachial plexus injury (BPI) and experimental spinal root avulsion result in loss of motor function in the affected segments. After root avulsion, significant motoneuron function is restored by re-implantation of the avulsed root. How much this functional recovery depends on corticospinal inputs is not known. Here, we studied that question using Celsr3|Emx1(More)
Two differently timed extracellular and intracellular enzymatic and mRNA peaks of tissue-type plasrninogen activator (t-PA) were induced following ionizing radiation. The first peak appeared within 10 min following \-irradiation but rapidly declined. The appearance of early t-PA mRNA transcripts and enzymatic activity were not prevented by actinomycin D(More)
To ensure equal chromosome segregation and the stability of the genome during cell division, Separase is strictly regulated primarily by Securin binding and inhibitory phosphorylation. By generating a mouse model that contained a mutation to the inhibitory phosphosite of Separase, we demonstrated that mice of both sexes are infertile. We showed that(More)
Celsr3 and Fzd3 regulate the development of reciprocal thalamocortical projections independently of their expression in cortical or thalamic neurons. To understand this cell non autonomous mechanism further, we tested whether Celsr3 and Fzd3 could act via Isl1-positive guidepost cells. Isl1-positive cells appear in the forebrain at embryonic day (E)(More)
