VEGFA and pancreatic ductal adenocarcinoma: In in vitro and in an in vivo subcutaneous mouse model of pancreatic ductal adenocarcinoma, they carried out a nanoscale intracellular drug delivery systems capable of multidrug delivery (verteporfin plus anti-VEGF monoclonal antibody bevacizumab) in a nano-photoactivatable liposome to enhance the efficacy photodynamic therapy combined with suppression of VEGF-mediated signalling pathways [80].
