Current and emerging molecular targets in glioma.

Gliomas are the most common and lethal neurological cancers Despite research efforts the prognosis for patients with malignant gliomas remains poor Advances in the understanding of cellular and molecular alterations in gliomas have led to the emergence of experimental molecularly targeted therapies This article summarizes recent progress in the development of targeted therapies for glioma focusing on emerging molecular targets including neuropeptide and neurotrophin pathways glutamate receptors epigenetic mechanisms and glioma stem cell targets Recent clinical trials of small molecules and antibodies targeted at growth factor pathways and intracellular signaling cascades are also discussed
