EVL and MIM/MTSS1 regulate actin cytoskeletal remodeling to promote dendritic filopodia in neurons.

Dendritic spines are the postsynaptic compartment of a neuronal synapse and are critical for synaptic connectivity and plasticity. A developmental precursor to dendritic spines, dendritic filopodia (DF), facilitate synapse formation by sampling the environment for suitable axon partners during neurodevelopment and learning. Despite the significance of the actin cytoskeleton in driving these dynamic protrusions, the actin elongation factors involved are not well characterized.

Optimized in vitro three-dimensional invasion assay for quantifying a wide range of cancer cell invasive behavior.

We describe a three-dimensional (3D) in vitro assay for quantifying cancer cell invasion into a 3D microenvironment with defined biochemical and biophysical properties. Researchers can quantify invasion dynamics (e.g.
