  • Title: [The vascular endothelial growth factor (VEGF): a model of gene regulation and a marker of tumour aggressiveness. An obvious therapeutic target?].
    Author: Grépin R, Pagès G.

    Abstract:
    VEGF represents a model of gene expression regulation. RAS/RAF/MEK/ERK and PI3 Kinase pathways, activated in response to growth factors stimulation or by oncogenes, contribute to its expression by activating transcription factors or inactivating proteins implicated in degradation of its mRNA. These factors (Sp1/Sp3, HIF-1 and TTP) constitute molecular markers of tumor aggressiveness. VEGF is overexpressed in solid or hematologic tumors. Thus, numerous compounds regulating angiogenesis by targeting VEGF have been developed. However, their effects are not as spectacular as expected. The existence of anti-angiogenic isoforms of VEGF could be a cause of their less potent activity. These different points are discussed in this review article.
