Renal Delivery of Adenovirus and Antisense Oligonucleotides in Rats by Retrograde Renal Vein Injection

Renal gene therapy may offer new strategies to treat diseases of native and transplanted kidneys. Several experimental techniques have been developed using viral, nonviral, and cellular vectors, although the effectiveness of such techniques varies widely depending upon the vector used, type of injection, species, and experimental model of renal disease. Here, we describe an optimized technique for renal delivery of DNA in rodents by retrograde renal vein injection as it is currently applied in our laboratory for adenovirus and nonviral vectors. This is an effective gene transfer method with lasting effect on gene expression in the kidney that modulates renal disease in rodents without any apparent harmful effect, thus having a potential therapeutic value for future clinical applications.
