AIM:To generate an adenoviral vector specifically targeting the EphA2 receptor(EphA2R) highly expressed on pancreatic cancer cells in ***:YSA,a small peptide ligand that binds the EphA2R with high affinity,was inserted into the HI loop of the adenovirus serotype 5 fiber *** further increase the specificity of this vector,binding sites for native adenoviral receptors,the coxsackie and adenovirus receptor(CAR) and integrin,were ablated from the viral *** ablated retargeted adenoviral vector was produced on 293T *** c targeting of this novel adenoviral vector to pancreatic cancer was investigated on established human pancreatic cancer cell *** demonstrating specifi c in vitro targeting,in vivo targeting to subcutaneous growing human pancreatic cancer was tested by intravenous and intraperitoneal administration of the ablated adenoviral ***:Ablation of native cellular binding sites reduced adenoviral transduction at least *** of the YSA peptide in the HI loop restored adenoviral transduction of EphA2R-expressing cells but not of cells lacking this ***-mediated transduction was inhibited by addition of synthetic YSA *** transduction specificity of the ablated retargeted vector towards human pancreatic cancer cells was enhanced almost 10-fold in *** a subsequent in vivo study in a nude(nu/nu) mouse model however,no increased adenoviral targeting to subcutaneously growing human pancreas cancer nodules was seen upon injection into the tail vein,nor upon injection into the ***:Targeting the EphA2 receptor increases specificity of adenoviral transduction of human pancreatic cancer cells in vitro but fails to enhance pancreatic cancer transduction in vivo.
