Myelination is a complex process requiring coordination of directional motility and an increase in glial cell size to generate a multilamellar myelin sheath. Regulation of actin dynamics during myelination is poorly understood. However, it is known that myelin thickness is related to the abundance of neuregulin-1 (NRG1) expressed on the axon surface.

The Neurofibromatosis type 2 tumor suppressor, schwannomin (Sch) is a plasma membrane-cytoskeleton linking protein that regulates receptor signaling and actin dynamics. We examined Sch's role in specifying morphological changes needed for Schwann cell (SC) function in vitro. Isolated Sch-GFP-expressing SCs extended bipolar processes 82% longer than those(More)
Metastasis accounts for most deaths from breast cancer, driving the need for new therapeutics that can impede disease progression. Rationally designed peptides that take advantage of cancer-specific differences in cellular physiology are an emerging technology that offer promise as a treatment for metastatic breast cancer. We developed CT20p, a hydrophobic(More)
The NF2 gene encodes a tumor suppressor protein known as merlin or schwannomin whose loss of function causes Neurofibromatosis Type 2 (NF2). NF2 is characterized by the development of benign tumors, predominantly schwannomas, in the peripheral nervous system. Merlin links plasma membrane receptors with the actin cytoskeleton and its targeting to the plasma(More)
