Abstract

Angiogenesis is fundamental for tumour growth and metastasis. Anti-angiogenic therapy has recently been added to the panel of cancer therapeutics. In pre-clinical models and patients, however, benefits from angiogenesis inhibitors, mainly targeting the VEGF pathway, have generally been short-term. Although several mechanisms have been postulated, mechanisms of resistance to anti-angiogenic drugs remain largely unknown. Anti-angiogenic therapies by hitting the vasculature increase hypoxia and cut nutrients availability in tumors. Understanding the complex effects of hypoxia on tumour cells is indeed necessary to unravel how tumours react and adapt to angiogenesis blockade, with the final aim to improve the therapeutic response. In this pro...
