| Research Abstract |
VEGF-targeted therapies have become an important treatment for a number of human malignancies. The VEGF inhibitors are actually effective in several types of cancers, however, the benefits are transiently, and the vast majority of patients who initially respond to the therapies will develop resistance.
I elucidate that one of mechanisms for the acquired resistance is the direct effect(s) of VEGF inhibitors on tumor cells expressing VEGF receptors. Treatment with bevacizumab and 5-FU induced two novel non-coding (nc)RNAs. These ncRNAs silenced p53 expression and inhibited p53 function. As the results, these ncRNAs induced malignant phenotypes in colon cancer cells, including over-activation of HIF1, angiogenic switching, resistance of apoptosis, aberrant cell cycle regulation, cancer stem-like phenotype, and resistance to bevacizumab. I revealed expression profiles of these ncRNAs in colon cancer patients; these ncRNA was overexpressed in patients treated with bevacizumab.
