Molecular mechanisms involved in angiogenesis and potential target of antiangiogenesis in human glioblastomas

Glioblastoma multiforme (GBM) is the most devastating and common primary malignant brain tumor in adults. Angiogenesis as a hallmark in glioblastoma has attracted more and more attention of the research community. Over the past years, several systematic studies have provided vital results in this field discovering alterations in unanticipated number of genes and other regulatory factors and the associated signaling pathways. Recent discoveries about such genes and signaling pathway associated with angiogenesis in GBM provide a picture of the genomic routes in angiogenesis and antiangiogenesis pathways and may lay the foundation for improved antiangiogenesis therapy and clinical care. In this review, we discuss several such recent progresses in the genes associated with GBM angiogenesis/antiangiogenesis pathways and explore the potential new targets for GBM treatment
