Cell, Tumor, and Stem Cell Biology Loss of Collapsin Response Mediator Protein1, as Detected by iTRAQ Analysis, Promotes Invasion of Human Gliomas Expressing Mutant EGFRvIII
Glioblastoma multiforme (GBM) is the most common and lethal primary human brain tumor. GBMs are characterized by a variety of genetic alterations, among which oncogenic mutations of epidermal growth factor receptor (EGFRvIII) is most common. GBMs harboring EGFRvIII have increased proliferation and invasive characteristics versus those expressing wildtype (wt) EGFR. To identify the molecular bas...
متن کاملLentiviral Mediated Expression of Soluble Neuropilin 1 Inhibits Semaphorin 3A-mediated Collapse Activity in Vitro
Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...
متن کاملBrain tumor stem cells: view from cell proliferation.
A small population of TSCs, which form neurospheres and possess the capacity for self-renewal, has been recently identified in adult and pediatric brain tumors. They differentiate into phenotypically diverse populations, including neuronal, astrocytic, and oligodendroglial cells in vitro and recapitulate original tumors in vivo. The understanding of brain TSCs has been greatly advanced by the k...
متن کاملThe Chemorepulsive Protein Semaphorin 3A and Perineuronal Net-Mediated Plasticity
During postnatal development, closure of critical periods coincides with the appearance of extracellular matrix structures, called perineuronal nets (PNN), around various neuronal populations throughout the brain. The absence or presence of PNN strongly correlates with neuronal plasticity. It is not clear how PNN regulate plasticity. The repulsive axon guidance proteins Semaphorin (Sema) 3A and...
متن کاملSemaphorin-3A is expressed by tumor cells and alters T-cell signal transduction and function.
An important aspect of tumor progression is the ability of cancer cells to escape detection and clearance by the immune system. Recent studies suggest that several tumors express soluble factors interfering with the immune response. Here, we show that semaphorin-3A (Sema-3A), a secreted member of the semaphorin family involved in axonal guidance, organogenesis, and angiogenesis, is highly expre...
