Integration into the host genome is a random unpredictable event, hence depending on the site of insertion, cellular function may be disturbed due to genetic disruption, concerns for insertional mutagenesis causing activation of oncogenes have protodol been observed.
Recently, there has been a rapid expansion in the use of adenoviral vectors for in vitro and in vivo gene delivery [ 9 ]. Virus-receptor interaction in an adenovirus system. Schematic illustration of generating recombinant adenoviruses depicting basic principle of three independent steps of 1 subcloning GOI into a shuttle vector which transfers the GOI into the pAd plasmid containing the adenoviral backbone 2 during homologous recombination in bacterial system, and 3 packaging recombinant adviral DNA containing GOI in cells complementing E1 in trans.
