In mammals, motile cilia cover many organs, such as fallopian tubes, respiratory tracts and brain ventricles. The development and function of these organs critically depend on efficient directional fluid flow ensured by the alignment of ciliary beating. To identify the mechanisms involved in this process, we analysed motile cilia of mouse brain ventricles,(More)
We characterized the interactions between plasminogen and neurons and investigated the associated effects on extracellular matrix proteolysis, cell morphology, adhesion, signaling and survival. Upon binding of plasminogen to neurons, the plasmin formed by constitutively expressed tissue plasminogen activator (tPA) degrades extracellular matrix proteins,(More)
Focal adhesion kinase (FAK) regulates numerous cellular functions and is critical for processes ranging from embryo development to cancer progression. Although autophosphorylation on Tyr-397 appears required for FAK functions in vitro, its role in vivo has not been established. We addressed this question using a mutant mouse (fakDelta) deleted of exon 15,(More)
BACKGROUND Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase critical for processes ranging from embryo development to cancer progression. Although isoforms with specific molecular and functional properties have been characterized in rodents and chicken, the organization of FAK gene throughout phylogeny and its potential to generate multiple(More)
Polyglutamine diseases are nine dominantly inherited neurodegenerative pathologies caused by the expansion of a polyglutamine domain in a protein responsible for the disease. This expansion leads to protein aggregation, inclusion formation and toxicity. Despite numerous studies focusing on the subject, whether soluble polyglutamine proteins are responsible(More)
