Abstract

Renal excretion in experimental hypertensive rats implanted with encapsulated human atrial natriuretic peptide (hANP)-producing cells is circadian periodic. Chinese hamster ovary (CHO) cells transfected with the plasmid hANP-cDNA were encapsulated in biocompatible polycaprolactone capsules for intraperitoneal implantation into two-kidney, one-clip (2K1C) hypertensive rats. During a 12:12 light-dark cycle, as compared to control CHO cells, the implantation of encapsulated hANP-producing CHO cells was associated with an increase in the net excretion of water, sodium and potassium, and with a reversal of the advanced circadian phases related to renovascular hypertension in 2K1C rats. The increase in blood pressure postimplantation was delayed, and increases in renal blood flow, glomerular filtration rate, sodium output, urinary excretion and urinary cyclic GMP concentrations were also found. Implantation of encapsulated hANP-producing cells affects circadian rhythms in kidney excretion functions of 2K1C rats, and may be useful for the treatment of cardiovascular disease.
