Brain disorders comprise a major burden for the society. Recent analyses of the neuropsychiatric disease-related gene polymorphisms as well as genomics and proteomics have identified the components of the extracellular matrix (ECM) and the cell adhesion molecules (CAMs) in the brain as pivotal for those diseases. The ECM/CAMs span the synaptic cleft and regulate the synaptic dynamics. Furthermore, ...

Breast cancer is the most frequently diagnosed cancer in women with ~1.1 million worldwide cases. Despite intense study, in a significant fraction of women, tumor progression and disease relapse is inevitable underscoring a crucial gap in our understanding of these important hallmarks. Currently, little is known about the biochemical networks controlling these processes. The host lab has shown a f ...
