title: Genetic manipulation of the kidney.
abstract: Successful gene transfer into specific renal structures allows for evaluation of in vivo effects of certain molecules on the structure and function of the kidney. It would also be useful for therapeutic intervention in renal diseases by introducing "beneficial" genes into the affected sites. Towards achieving these goals, several gene transfer approaches have been developed using retrovirus, adenovirus and liposome. By introducing these gene transfer vectors via particular access routes, it is feasible to selectively manipulate the function of certain renal structures. Through the renal circulation, exogenous genes can be targeted to the vasculature and glomerulus, and possibly to the proximal tubules. Using a retrograde approach via the urinary tract, access to the collecting ducts can be gained. Implantation of genetically modified cells under the capsule of the kidney allows for diffusion of transgene products into the interstitium. Transplantation of embryonic metanephric tissues also provides a biological window for genetic manipulation. Furthermore, utilisation of fertilised eggs or embryonic stem cells would enable the creation of "transgenic kidneys" or "gene knockout kidneys". This article summarises the current experience with gene transfer to the kidney and addresses the potential strategies in vivo.
