VEGF-R1 as a Potential Molecular Target for Anticancer Therapy

Abstract

The possibility of using VEGF-R1 receptor for targeted therapy in oncology was investigated. Using the approach to measuring the protein content in intact nuclei of cells, which was developed by us, we showed the presence of this receptor in the nuclei of tumor, but not normal cells. A direct correlation between the level of VEGF-R1 expression in the nucleus and the degree of malignancy of tumor cells, indicating the prognostic value of this parameter, was found. The mechanisms of the functioning of this receptor and the pathways of inhibiting its activity are discussed, and the validity of the selection of VEGF-R1 as a molecular target for anticancer therapy is conformed.
