Regulation of gene expressions in vivo by anti-VEGF therapy


ABSTRACT: U87-EV human glioblastoma xenograft tumours is therapeutically treated by bevacizumab, a humanized anti-human VEGF mAb, when tumour is established in BALB/c SCID mice. At the end point, collect tumour samples and extracted total RNA for microarray to investigate the gene profile changes compared to control. These include the genes from human tumour cells and mouse host stroma cells. 3 control samples versus 3-bevacizumab treated samples

Limited clinical benefits derived from anti-VEGF therapy have driven the identification of new targets involved in tumor angiogenesis. Here, we report an integrative meta-analysis to define the transcriptional program underlying angiogenesis in human cancer. This approach identified ELTD1, an orphan G-protein-coupled receptor whose expression is induced by VEGF/bFGF and repressed by DLL4 signaling. Extensive analysis of multiple cancer types demonstrates significant upregulation of ELTD1 in tumo  ...[more]
